IntroductionActivated Exchanger Design & Rating (EDR) is a new Activated Analysis tool available within AspenTech’s V8.4

simulators, Aspen Plus® and Aspen HYSYS®. Like Activated Energy Analysis and Activated Economic Evaluation, Activated

EDR helps process engineers quickly evaluate feasible design alternatives and immediately assess the impact on

flowsheet capital and operating expenditures.

Activated EDR provides an easy way to convert simple heat exchanger models to rigorous models, and provides quick

access to rigorous model details. The EDR dashboard uses visual indicators to convey information about heat exchangers’

model status and shows all operational risks, if any, that have been detected in rigorous heat exchanger models.

New Capabilities

• Convert simple heat exchanger models into rigorous designs in one click to obtain a fully rigorous, cost-optimized

geometry that accurately models thermal and hydraulic performance

• Easily track and change the model-type for all heat exchanger equipment in the simulation

• Instantly view operational risks, such as vibration and erosion, right from the flowsheet

Overview of the User Interface

Starting Activated EDR

EDR Activation is turned on and off from the Activated Analysis panel. Open the Analysis Panel by clicking on the

Activated Analysis button on the Home ribbon (Figure 1).

Figure 1. Opening the Activated Analysis panel

Click the heat exchanger icon to turn it on and click the close button to turn it off (Figure 2). Opening and closing the EDR

dashboard does not affect the EDR models in your flowsheet; it will not automatically convert a simple model to rigorous

and vice versa. It will simply reveal more information about the heat exchanger models in your simulation and provide

access to EDR controls.

The EDR Dashboard

The dashboard is the first component displayed when you activate EDR (Figure 3). It contains two pie charts: Model

Status and Operational Risk.

Figure 3: The EDR dashboard

The Model Status Pie Chart

The Model Status Pie Chart shows relatively how many exchanger models in the flowsheet are rigorous EDR and how

many are simple. Rigorous EDR models provide much greater accuracy in modeling the actual operation of heat exchanger

equipment in a process as compared to simple models. The percentage of grey in this chart represents an opportunity to

improve the fidelity of the process model.

Simple models provide a very limited amount of sizing data that is only accurate within a small range of operating points.

Rigorous models provide full heat exchanger geometry, and model heat transfer and hydraulic performance as process

conditions change.

The Operational Risk Pie Chart

The Operational Risk Pie Chart shows the proportion of exchangers in the flowsheet that contain identified risks. Only

rigorous models can predict when an operation risk is present, therefore no operation risk status is given for simple

models. For rigorous models, the yellow section of the pie chart indicates a warning was detected by EDR.

All of the operation risk warnings that are identified by EDR have been classified into categories for Activation. The yellow

categories for each model type are shown below, as well as a sample of the red risks for Shell&Tube exchangers. Red risks

are reserved for the most serious risk types and are extremely rare.

Color Model Status

Grey Simple heat exchanger

Blue Rigorous exchanger

RedRigorous exchanger,

calculation error

Color Operation Risk Level

Grey Simple heat exchanger

Green Rigorous exchanger, no warnings

Yellow Rigorous exchanger, operation warnings detected

Red Rigorous exchanger, serious risks detected

Model Status Flowsheet Components

Model Status highlights circle rigorous exchangers in blue (Figure 5) and simple exchangers in grey (Figure 6). Hover over

a blue highlight to see a setting plan for the EDR design, as well as key geometry and heat transfer information. Hover over

a grey highlight to see information about the simple model and convert the model to rigorous.

Operational Risk Flowsheet Components

Click on the Operational Risk panel of the dashboard to reveal which exchangers contain operational risks detected by

EDR. Hover over the highlight to show which kinds of warnings are present for that exchanger (Figure 7). Click on the

circle at the flyover’s heading to reveal a 2nd level flyover that shows the exact warning found by EDR (Figure 8).

The Activated EDR Summary TableThe Summary table is an organized list of all heat exchangers in your flowsheet. From this table you can access rigorous

exchanger forms, convert models from simple to rigorous and rigorous back to simple, and view operation warnings for all

models in your flowsheet (Figure 9).

All of the columns in this table can be sorted ascending or descending. The last three columns can also be filtered. This

allows you the flexibility to look at all models in a particular flowsheet, sort by model status, look at only heat exchangers

that contain risks, and etc.

Summary Table Organization

Column 1:

Exchanger Name

Displays the title of the unit operation block for that exchanger. If the model is rigorous, this

title will be a link to open the unit operation form and display the EDR model details.

Column 2:

Subflowsheet:Shows the location of the exchanger if it’s located in a subflowsheet or hierarchy block.

Column 3:

Model Status

Contains a toggle button that shows the EDR model type or “Convert” for simple models.

Click on this button to convert the exchanger from simple to rigorous or vice versa.

Column 4:

Operation Risk Status

For rigorous models, an indicator shows the exchanger’s operational risk status. Click the

indicator to view the operation warnings for this heat exchanger. Click on the column

heading to view a summary of all risks.

Converting ModelsThe chart below in Figure 10 shows the possible conversions between simple unit operations and the corresponding

rigorous EDR models in Aspen HYSYS.

Rigorous Model Types Supported in Aspen HYSYS:

Figure 10. Simple to Rigorous Model conversions

Converting a Simple Model to Rigorous EDR

Convert forms for simple models can be accessed from either the Activated EDR Summary Table or the Model Status

Flowsheet Flyovers, shown below in Figure 11.

Figure 11. Accessing Convert forms

Click on the Convert button from either of these locations to begin model conversion. The form shown below in Figure 12

will open.

Convert forms in HYSYS

Heat Exchanger and Air Cooler unit operations allow for autosizing, interactive sizing, and file import to convert to a

rigorous Shell&Tube or AirCooled, respectively.

On the Convert form, complete the following steps in Figure 12:

Special Conversions for PlateFin and FiredHeater Models

To convert these models to rigorous, an EDR file must be imported; rigorous sizing is not supported in simulation. To

import, click on the Convert button then follow the on-screen instructions to import the EDR file and complete

specification in HYSYS.

Converting a Rigorous EDR Model to Simple

You can access the form to convert rigorous models back to simple from the Activated Summary Table. Click on a button

in the 3rd column for an EDR model type (Figure 13).

choose the EDR template

from the browser. If

importing a file, select the

EDR file to import from the

browser.

3. Click the Convert

button to continue.

method from the radio

buttons in the top box.

When you click on this button, instructions for the particular model will appear. Read the steps that will be used to achieve

the conversion.

Then click on the Convert button (Figure 14) to go to the forms where those steps can be completed.
