Guidelines for Reporting and Assessment

INTRODUCTION

The final year Design Project represents the most challenging and extensivepiece of project work that you have undertaken to date. It makes demands notonly on your individual technical ability but also on your ability to communicateand co-operate with other members of a project team in the efficient productionof a successful design and in its efficient communication to other people outsidethe team through a properly structured project report.

The design project report forms the only tangible result of the design teamsefforts and nowhere else does the level of coordination between team members

become more visible. Even well executed designs can be marred by poor reportpresentation and to help avoid this pitfall the following guidelines have beendrawn up as a basic standard to which you must work. In addition they providea framework which you can use to plan and monitor the progress of your projectteam towards completing the project successfully by the report submissiondeadline.

ASSESSMENT

There are a total of four (4) assessments in the design project, given as follow.

Task 1 Design Basis and Preliminary Flowsheet

Task type: GroupReport hand-in date: 19th November 2012Oral assessment date: 27th November 2012

a. Oral Assessment

It is common for competitive tenders to go through an early stage of assessmentby the client company. This is to allow the client to question the design teams at

an early stage, check they are satisfied with the design basis and provide anyfeedback before committing a relatively large sum of money to undertake a moredetailed design. The oral assessment represents the first meeting with the clientcompany after receiving the initial project brief.

Each group will present the design basis and preliminary flowsheet (in A3 size) toa panel. All group members should be prepared to answer questions from thepanel about any aspect of your design at its current stage, particularly how yourdesign meets the project brief and your own basis of design. Formative feedbackwill be given to each group at this stage.

Weighting: Task 1a comprises 40% of mark in Task 3.

b. Group Report:

The report should contain the following: Basis of design. Maximum 1 page. This is your groups own interpretation

of the project brief, and states what you think are the unique selling pointsof your design. Financial, safety and environmental criteria should also bespecified.

Review of alternative process configurations. Maximum 3 pages of text,plus appended flowsheets if necessary. This is the justification for whyyour flowsheet appears the way it does at this stage, and how it relates toyour design brief. You should state any steps you have taken to confirm orrule out certain process configurations, as well as the basis, information orassumptions that you used to do this.

1 page process flowsheet of A3 size. This should show all of the unitoperations and how they are connected, plus details of all the feed,

product and waste streams. Design temperature and pressure areneeded for all process streams and equipment; while streamflowrates are not needed at this stage. Heating and cooling stagesshould also be shown, but heating and cooling duties are not needed atthis stage.

The Group Report is part of the Interim Report to be submitted at the end of theAutumn semester. Page limit for the group report is 30 pages (with a maximumof 15 pages for the appendices).Weighting: Task 1b comprises 20% of mark in task 3.

Task 2 Individual Designs

Task type: individual

a. Equipment Design

Each student should produce detailed design of one major equipment and oneminor equipment at the preliminary level (see Section V for details). Your designshould allow the potential client to obtain the following information:

Equipment dimensions Details of internals, e.g. catalysts or packing material Materials of construction Operating temperature/pressure, and distribution throughout the

equipment Mechanical design and operating/maintenance considerations

Technical sheet hand-in date (for assessments): 1 April 2013 (complete reportwrite-up is not necessary).Weighting: Task 2a comprises 35% of total module mark (25% for major and10% for minor equipment).


3/21

3

Oral assessment: Each student will present the major equipment design to apanel, and should be prepared to answer questions from the panel about anyaspect of your design. Formative feedback will be given to each student.

Weighting: oral assessment comprises 60% of mark in Task 4.

b. General Aspects

Each student is expected to master some general aspects of the design projects.Hence, each group member may choose to be the Chief Engineer for one of thefollowing sections:

Section VI - Section Energy and Utility Balances Section VII - Environmental Impact and Protection

Section VIII - Process Operation and Safety Section IX - Process Economic Analysis

Technical sheet hand-in date (for assessments): 15 April 2013 (complete reportwrite-up is not necessary).Weighting: Task 2b comprises 15% of total module mark.

Task 3 Final Plant Specification

Task type: Group

Report hand-in date: end of 29 April 2013Weighting: Task 3 comprises 25% of the total module mark, in which 40% iscontributed by Task 1.

The group is to produce an Extended Summary at this stage (Section I) and thefinal report for the entire project. A two (2) page description and justification isneeded for major changes made.

At the end of the project the group must agree the % contribution of eachmember to the group components of the project. We will consider this weightingwhen collating the final marks for the project. This should not be viewed as anopportunity to score more marks by doing more work on group elements of theproject.

Page limit Tasks 2 and 3 should consist not more than 75 pages. As a roughguide, the main report should have a total of 25 pages; while the individualappendices are 50 pages. It is up to each student to decide what to be includedin the main report and appendices.

Task 4 Critical Evaluation

Task type: individual

Report hand-in date: 6 May 2013 (exact date to be announced in the beginningof Spring semester)


4/21

4

Weighting: Task 4 comprises 25% of the total module mark, in which oralassessment of major equipment design (part of Task 2) contributes 60%.

Students in different groups will have designed equipment that is very similar to

each other. Hence, each student will receive copies of the detailed designs of twoother students. Each student will need to produce a critical evaluation of his/herown design plus the designs of two other students.

FULL REPORT STRUCTURE

In industry a report of the type you are to prepare would be accessed by a widevariety of people ranging from engineering specialists (i.e. not only otherchemical engineers) right through to senior managers. Specialists may accessonly data sheets and detailed calculations whilst senior managers may read only

the summary. With this in mind your report should provide easy access toinformation anywhere from the most specific to the most general levels of detail,as necessary. A fairly standard format has evolved in industry to achieve this aimwith relatively minor variation between organisations. Within a singleorganisation however the format is usually quite rigid, to ensure internaluniformity for all such documents, and the following guidelines set out our own

In House report format.

The report must be structured on a sectional basis as follows (with deadline):

SECTION CONTENTS

Each section must begin with a title page listing those who have contributed tothe material it contains. The material itself should be arranged in sub-sections


5/21

5

numbered on a decimal basis (e.g. VIII.3 Emergency Plant Shut-downProcedure). Pages should be numbered within sub-sections, each page carryingits unique number and authors initials in the top right-hand corner (i.e.Section.Sub-section.Page, for example VIII.3.4). Expected content for each of

the main report Sections (I-IX) is as follows:

Title Page: Report title, code number/letter, date of issue, authors, academicand industrial supervisors.

Contents: List section and sub-section headings with page numbers.

Section I. Extended Summary: Comprises three sections:(I.1) Executive Summary (300 words max): a normal summary

commenting on all the main aspects of the project. Most important

will be particular features of the process selected, details of anymajor safety or environmental issues and the results of the processeconomic analysis.

(I.2) Appraisal of Group Design (500 words max): view of the wholedesign group on their work in the main sections including featuressuch as:well executed aspects of the design- difficult aspects of the design and how these were overcome- areas of uncertainty remaining in the design- how the design might be improved.

(I.3.1 onwards) Appraisal of Individual Design (300 words max each):

view by each student of their own work on detailed design includingthose aspects listed for I.2 above.

Section II. Design Basis: A statement of the requirements to be met by theplant itself (capacity, feed/product/utility specifications etc.) and by the designchosen (e.g. low operating or capital cost, plant lifetime, return on capital, designcodes etc.). Design criteria having a major influence on the design must behighlighted. Some of this information (operating/capital cost, return on capital,etc.) will only become certain upon completion of the detailed design and hence,this chapter needs to be updated towards the end of the project.

Section III.Process Background: Information to be included here comprises:Markets for the product and their growthProduction scale and site selectionReview of alternative processes

Give a brief review of global and local markets for the product including the mainuses. The production capacity, based on the product growth rate, and the sitelocation should also be covered within the scope set in your project assignment.

The process route must be justified on a range of considerations including safety,environmental impact, economics (via economic potential evaluation), raw

material supply and sustainability. A concise description is needed for all


6/21

6

alternative processes considered including state-of-the-art technologies (e.g.patented processes).

Section IV.Mass and Energy Balances: This section must comprise:Engineering line diagram (ELD)Process descriptionMass balance

The Engineering Line Diagram (ELD) shows the arrangement of the processequipment within the plant together with the interconnecting pipework carryingthe process streams. Equipment is to be represented using standard symbolsand identified by individual equipment number (as listed in Section VII). Allprocess streams should carry a stream index number corresponding with entriesin the mass balance. All significant temperatures and anchor pressures should

also be shown. It is strongly recommended that ELDs are produced using MSVISIO. A3 sheets may be used as working drawings but A0 should be used formeetings with the industrial adviser and in the final report.

The Process Description should refer to the ELD and provide a conciseexplanation of the processing operations involved.

Ideally auxiliary equipment, such as process instrumentation, control loops andpressure relief devices, should also appear on the ELD but if it becomes toocongested then these items can be shown on a second copy of the ELD (e.g. inplace of temperatures/anchor pressures etc.) labelled for this particular purpose.

To avoid overcrowding on a single ELD some processes may be better shown onseveral (properly numbered) sheets.

The mass balance should contain a componential breakdown and total for eachprocess stream using its stream index number which cross-references with theELD. The temperature and pressure of each stream must also be quoted. Thebasis for the mass balance must be clearly stated. A footnote should also begiven indicating the location of the underlying detailed calculations (presented inAppendix AIV or beyond). Where a process simulation package (Aspen HYSYS,Aspen Plus, DESIGN II for Windows, SuperPro Designer and UniSim Design areavailable in UNMC) has been used, verification against manual/hand calculationsshould also be presented.

An Energy balance is to be presented for the whole plant based on energy flowsfor each equipment item in the ELD. Reference should be made to the underlyingdetailed calculations presented in Appendix AIV or beyond.

Section V. Equipment Design: This section summarises the design ofequipment items appearing in the ELD and must comprise

Equipment ListEquipment Specification sheets

The Equipment List includes all process and auxiliary equipment items on the

ELD (e.g. heat exchangers, pumps, compressors). Each equipment item has anidentification code number, a name and a Lead Engineer responsible for its


7/21

7

design and these should be indentified accordingly (see Attachment A). List theequipment items in service groups (e.g. all heat exchangers grouped togetherwith suffix E, all towers grouped together with suffix T, etc.) and sequence themwithin a group in order of ascending item number. Item numbers normally

increase in moving from feed to product through the ELD.The equipment list is an important document in ensuring no item is overlooked inpreparing the ELD, plot plan or equipment specifications or in compiling capitalcost data.

For every item in the equipment list an equipment specification sheet(sometimes called a data-sheet) must be presented in the same sequence as theequipment list. All equipment specifications must carry the followinginformation:

Item Code NumberItem Name (plus any further details required for clarity)Authors NameReference by page number to supporting calculations

Equipment specifications may be prepared at three alternative levels of detail,according to Attachment B. The information contained must be adequate for thecapital cost of the item to be estimated. As a guide, some specific examples aregiven as Attachments C, D and E and these are referred to below.

First, a thorough chemical engineering design of most of the equipment involved

can be attempted (e.g. reactors, towers, drums, heat exchangers etc) but somemore specialised items (e.g. those involving motor drives such as pumps andcompressors) require thorough design by an equipment vendor. It is then your

job to provide the vendor with adequate information to arrive at a suitable designin the form of a load-sheet (see Attachment C, an example for a compressor).

Secondly, in the majority of cases where a thorough chemical engineeringdesign is possible, you may choose one of two levels of detail:

i) PRELIMINARY - Involves the use of shortcut calculations, rules of thumb, etcto obtain a that is adequate for outline cost estimation and plot planpreparation. For instance, for a heat exchanger, you would choose a typicaloverall heat transfer coefficient for the service to estimate the surface area.In the case of a distillation column, you would use a quick estimatingtechnique based upon vapour-liquid flowrate, to set the column diameterand a typical tray spacing, tray efficiency and an estimated number of idealtrays to set the vessels tan-tan length. This level of design would allow youto complete the front page specification sheet for either item which (seeAttachments D-I for a heat exchanger or E-I for a tower).

ii) DETAILED - In this case you will progress the design with more detail andprecision. For a heat exchanger, instead of choosing a typical heat transfercoefficient, you will calculate a value taking into account flowrates, tube size

and arrangement, baffle spacing etc. For the column, instead of using aquick sizing method, you would develop a rigorous method and include

proper tray design, give detailed consideration to arrangements for handlingfeed entry, reboiler return and the internal liquid and vapour flows, as wellas preliminary design of condenser and reboiler. Obviously this requiressupplementary data-sheets such as Attachments D-II and E-II.

Note: In practice all equipment specifications would be completed at thedetailed level. We accept you may not be able to perform a detailed designfor every item of equipment, due to limited time. Hence, each student isexpected to design in detail one major piece of equipment. In additionto this, each student is expected to design one piece of minor equipmentat the preliminary level. In other words, each student should submit atleast one detailed design of a major piece of equipment and the preliminarydesign for one minor equipment (e.g. pump, compressor, heat exchanger).

Heat exchanger data-sheets (e.g. Attachments E-I and E-II) are suitable for most

services and you may use these as templates. Vessels such as reactors andtowers all tend to be different and in general you will need to provide your ownversions equivalent to Attachments D-I, II etc. Vessel sketches need not bedrawn exactly to scale but should be clearly dimensioned. Whether at

preliminary or detailed level, a vessel sketch must be included in eachequipment specification. The design team should agree and use a set format forload-sheets and other data-sheets where appropriate.

Section VI.Energy Recovery and Utility Balances:

For energy intensive processes, a heat recovery system may be designed usingprocess integration techniques whereby a heat exchanger network could bedesigned to achieve the maximum energy recovery targets and Grant CompositeCurves may be utilised to decide the level of hot and cold utilities required.

Utilities normally available include steam, cooling water, electricity, fuel (oil orgas), inert gas etc. and their various usages (consistent with the mass balance)must be listed. In more complicated cases, typically the steam balance (withsteam at various conditions), presentation as a line diagram is recommended(again, using MS VISIO) which cross-links to stream numbers in the ELD (seeAttachment F which, whilst incomplete in lacking general instrumentation, servesto illustrate the format required (see also Notes 8 to 10 on Report Presentation).

Section VII. Environmental Impact and Protection: This section shouldsummarise how all forms of discharge from the plant into the environment(arising either continuously or intermittently) will be handled. For continuousreleases (e.g. wastewater, sour gas, sludge), attention should be paid to thesteady discharge rate; whilst for intermittent releases (e.g. arising fromemergency pressure relief, plant shut-down, spent catalyst, etc.) the totalquantity is important. The relative severity of each discharge should beidentified. Systems for handing or treatment should be identified for anydischarge not directly compliant with the Malaysian Environmental Quality Act(EQA) 1974 (USEPA guidelines should be used for toxic chemical emissions). The

scope of some projects may also include design of equipment items for effluentabatement.

Section VIII. Process Operation and Safety: Information to be includedin this section comprises:

Plant safety studyProcedures for normal plant start-up, operation and shut-downProcess control strategyProcedures to handle emergencies

It is of the utmost importance to design a plant that is safe and easy to operate.Make reference throughout to the plant ELD showing strategic valves andpressure relief arrangements (see Section IV). The process control schemeshould be described as part of the normal plant operating strategy.

The plant safety study should be based on the ELD and should include a coarse

scale hazard analysis for the complete plant, a detailed HAZOP study of a plantsub-section (done as a group) and a statement of how you propose to deal withthe hazards identified through equipment design and operating procedures. Filesupporting detail in an appendix (e.g. appropriate material safety data sheets(MSDS), safe procedures for handling and processing hazardous materials etc)Emergency operating procedures should be developed to cope with potentialhazards and failures and cross referencing to process control and the plant safetystudy is likely.

Section IX.Process Economic Analysis: This should include a full analysis ofoperating and capital costs and a discussion of the process economics. Plant item

capital costs will follow from the equipment specifications in Section VII. Refer todetailed calculations in an appendix, including any preliminary capital costestimates completed at an intermediate stage in the design which can also bereferred to).

Appendix AIV onwards: Free use of AIV and subsequent appendices should bemade to present supporting detail. This will mainly comprise detailedcalculations, especially those underlying the equipment designs, and theirpreparation will most likely be undertaken by individual authors. The objective isto allow the procedures and methods chosen and used by the designer to bevalidated both technically and numerically. Try to be concise. For repetitive oriterative calculations you should provide one sample calculation and summariseor tabulate the main outcome. Where computer programs have been used theresults should be summarised (perhaps using tables or graphs) and the programsproperly documented. Operation of a program should be described with referenceto a single code listing and wholesale inclusion of printer output should beavoided. See also Note 10 on presentation.

Note: that in all parts of the report, no credit will be given for theinclusion of marginally relevant material downloaded from the web. Ifno reference as to the original source is cited this will be treated asplagiarism.

PROJECT SCHEDULING AND PROGRESS

An interim report that consists of Sections II to IV (design basis, processbackground, mass and energy balances) should be completed towards the end of

the autumn semester, and must be handed in by 4.30 pm on Monday 19th

December 2012. The final report (Sections V to IX) together with a CD thatcontains an electronic copy of the report, must be handed in by the specifieddeadline (29 April 2013).

Since the Design Project is the single most important piece of work in the wholeundergraduate course, and it resembles the proposal submitted for bidding for aproject in a consultancy company, a penalty of 5% reduction per day(including weekends) is STRICTLY implemented for late submission.Please note that a submission at 4.31 pm on each specified deadline isconsidered as late submission. Students who have submitted late by 5 days

(without a valid Extenuating Circumstances Form) are considered tohave failed the particular task. Furthermore, projects submitted late must besent directly to the project coordinator (Prof Ir Dr Dominic Foo), where anexplanation for late submission is needed.

PROJECT SUPERVISION AND ACCESS TO ACADEMIC STAFF

Progress towards successful completion of the design project exercise is theresponsibility of the design team members, as is equitable division of workloadand responsibility for particular plant items.

The role of the supervisor is to provide general guidance on the project and toact as a sounding board for discussion on specific design points. Othermembers of academic staff may also be consulted on specialist areas; however,the project supervisor must be the first port of call on a problem. In any casewhere a group member is not contributing (behaving as a passenger), thesupervisor should be informed.

A Research Assistant (RA) will be made available to provide additional help andguidance during the course of your design project. You will be told which RA isavailable for your group, but be aware that there is limited RA time allocated forassistance and a prior appointment is required for any meetings. Do not go tosee them without first having arranged an appointment.

In the early stages of a project, you will need to have regular meetings with yourdesign project supervisor (ideally once a week) or RA whilst the basic form of theproject is established and you gain confidence at being able to complete thework. However in the later stages (i.e. Spring semester), the intention is thatyou, individually and as a group, become largely independent, with sufficientconfidence to apply the principles you have learnt through the course. Hence, therequirement for frequent contact with the project supervisor should be reducedand you should be able to work, except in extremis, unsupervised.

As part of Teaching Quality Assurance procedures a Record Card will be used todocument meetings and consultations with academic staff or the industrial


11/21

11

adviser. The Record Card does not form part of your assessment. You will beissued with individual record cards at the start of the project and entries will bemade by the project supervisor after each routine meeting, and also by othermembers of academic staff and industrial tutors after consultations. If you fill the

first record card, then a second can be obtained from the project co-ordinator(Prof Ir Dr Dominic Foo). At the end of the project all record cards must be filedin Appendix AII.

NOTES ON REPORT PRESENTATION

A high standard of presentation is expected throughout the report. Sections I toIX form the main report and should provide a complete statement of the design.In general only the outcomes of calculations will be quoted there together withreference being given to the location of underlying calculations in the

Appendices.

The following specific points should be followed.

1. The page limits are to be observed.

2. Writing/text should be on one side of the paper only.

3. All sections shall be presented in typed (word-processor) format.

4. Section and sub-section numbers should be designated at an early stage

to allow correct cross referencing from the very first stages of writing.

5. To make access to the report easier, dividers with labelled tabs should beused between sections and, where appropriate, within sections.

6. Calculations and specifications in the report should be in consistent unitsand a standard basis should be agreed by the project group andsupervisor at the outset.

7. Each section should begin with a title page listing those who havecontributed to the material presented in that particular section of thereport. Every page of the report (main body and appendices) shouldcarry a full unique reference number (Section.Sub-section.Page) in thetop right hand corner together with the initials of the author (Thisinformation is in addition to the particular requirements for equipmentspecifications - see sample sheets).

8. It is strongly recommended that ELDs are produced using MS VISIO.Large diagrams should be on standard sized paper (e.g. A0, A1, A2, A3)folded flat so as to fit tidily into the A4 report file.

9. ELDs and utility balances must carry Date of Issue (and any RevisionDates) in addition to Title, Authors Name etc..


12/21

12

10. Where computer code is presented this should be annotated andaccompanied with an explanatory flow diagram. Results of computer runsshould be summarised (e.g. in graphs or tables). A4 sheets should bepreferred and wholesale inclusion of stream summary results from

simulation is unacceptable.

FINAL CHECKLIST

Apply the following checklist during the final phases of writing up. It is intendedas a means of ensuring that your design report is properly complete and cross-referenced correctly.

1. Does every page show a unique number and its author?2.

Are all the mandatory sections present?

3. Are all plant items uniquely numbered?4. Do all process streams carry an index number?5. Are all the plant items listed in Section VII also costed in Section IX?6. Does every specification in Section VII carry an appropriate item name and

number. Is there adequate cross-referencing to supporting calculations?Does every specification have an identified author(s)?

7. Do plant item and stream numbers on the ELD correspond to the text,especially in Sections IV, VII, VIII and IX?

8. Have all literature sources been listed in Appendix AI?9. Have all literature sources been cited in both the main report and

appendices?

10.Have all documents (including all chapters in MS Word, drawing,simulation and spreadsheet files) being included in the CD for electronicsubmission?

11.Has Section II (Design Basis) been updated to correspond with the designpresented in the final report?

12.ELD of A0 size is included in the final report. All process streams shouldbe labelled with temperature, pressure and main components that arepresent.
