1. Calibration Input Data

Calibration input includes process data and specific targets for the calibration run to meet.

1.1 Feed Enter the feed rate, D86, TBP, or D2887 analysis, overall PNA, a full gas chromatographic (GC)

breakdown of the feed by carbon number and type, or a combination of these.

1.3 Yields and properties

Yields and properties, based on a normalized product and straight cuts, are targets calculated by REF-

BAL and copied into the Calibration Input worksheet. The REF-SIM model tries to match these targets

with Calibration Factors when a Calibration case is run. These targets are calculated by REF-BAL:

1. C5+ yield

2. C5+ RON

3. C5+ RVP

4. Hydrogen (weight percent of feed)

5. Naphthenes (volume percent in C5+)

6. Light ends yields (as weight percent of feed)

7. BTX yields (weight percent of feed) if applicable: benzene, toluene, xylenes, C9 aromatics, C5 paraffins, C6 paraffins,C7 paraffins, C8 paraffins and MCP

88

Petrosim

:

1.4 Ecinomics

Pricing can be added to the Calibration Input sheet if desired. Although these values are not used in

calibration, they are available for consistency and for comparison with cases in the other modes.

2. Predict Input Data

Process input information includes:

Feed rate

Feed quality (overall PNA and Distillation or Composition (GC analysis))

Reactor conditions

Separator and recontactor conditions

Catalyst information

Pricing In addition to the process information, you select options in the following categories: 1. Closure option: inlet temperature, C5+ RON or C6+ RON 2. Recycle rate 3. Catalyst activity 4. Pressure calculation 2.1 Operating Conditions

3. Results Worksheets

REF-SIM has Results worksheets corresponding to Calibration, Predict and Optimizer Input worksheets.

3.1 Calibration Results worksheet The Calibration Results worksheet lets you average the Calibration Factors and calculate the standard deviation factors. Select the Calibration cases to include by entering non-blank characters in cells on row 1 to the right of the title, Statistics. The averaged Calibration Factors and standard deviations are displayed in columns BN through BP at the right end of the Calibration Factor section. To use the average Calibration Factors in Predict cases, select the Copy function to copy the factors over to the Predict Input worksheet.

95

Petrosim

:

The Result worksheets for the Predict and Optimize Modes are the same as the Calibration Result worksheet except:

The Predict and Optimizer worksheets do not have the Calibration Factor averaging section

The Predict Result worksheet contains indices and text material used by the Optimizer Input and various dialog boxes

The Optimizer worksheet does not contain output for Calibration Factors because they are the same for all Optimization cases

96

Petrosim

:

3.2 Comparison worksheet The Comparison worksheet compares two cases from the Calibration, Predict, and Optimizer Results worksheets. After you select the worksheet and case, the program calculates both absolute and relative differences between the values in each case. These differences are displayed as Delta and % of 1st in columns G and H.

97

Petrosim

:

3.3 Summary Worksheet

The Summary worksheet displays summary data for a specified Calibration, Predict, or Optimizer Results case so you can quickly review and evaluate the data. This worksheet is formatted to be suitable for printing on one page. Select the case to be displayed using the list box and spinner.

98

Petrosim

:

4. Calibration Case Checklist Before running the model in Calibration Mode, check these items:

1. Check REF-BAL results to make sure model balance closure is within 1% and hydrogen closure is within 0.5%, and copy into Calibration. Remember to add additional process information on the Calibration Input worksheet and static unit configuration data on the Design worksheet.

2. Run the model using the RUN button or choose Run, Calibration Case, from the REF-SIM menu. Turn off Auto Tune for the first run. If it runs successfully, turn on Auto-Tune and run after each new target is added.

3. If the model fails, view the Error Log. The cause of the failure is listed at the bottom of the file. The message should provide enough information for you to correct the problem. After correction run the model again.

4. If the model runs successfully, the results are loaded into the Calibration Result worksheet. Check the Error Log to ensure there are no abnormal warnings.

5. Use the Summary worksheet to check input data quality.

5. Predict Case Checklist To run the model in Predict Mode:

1. Select the Predict Input worksheet. 2. If running a Primed Predict, select a successful Calibration case. 3. Select a catalyst activity option for the Predict case.

Option 0 is specific to cyclic units and computes activity from start of run.

Option 1 is for all types of reformers and uses previous calculated activity.

Option 2 is specific to semi-regen units and integrates activity decay.

Options 3 and 4 are specific to CCR units; they compute catalyst activity for the regenerator that is down or starting up, respectively.

Note: If Option 3 or 4 is selected, the regenerator on or off time must be given. Also, if Option 4 is selected, the catalyst decay rate is required.

4. Select the reactor closure option:

Option 0 closes on specified reactor inlet temperatures. Note: If Option 0 is selected, you can also specify fixed reactor inlet temperatures.

Option 1 closes on specified C5+ RON.

Option 2 closes on specified C6+ RON.

Option 3 closes on specified volume percent aromatics in C5+.

Option 4 closes on methylcyclopentane.

5. Enter the new process target values and change options (such as feed rate, feed components, H2/HC ratio, etc.) If a target or option cell is left blank, the value from the previous case is used.

6. Run the Predict Mode using the Run button on the worksheet or the Run option on the REF-SIM menu.If the model fails, look at the Error Log. The cause of the failure is listed at the bottom of the file. The message should provide enough information for you to correct the problem. Correct the problem and run the model again.If the model runs successfully, the results are loaded into the Predict Result worksheet. Check the Error Log to ensure there are no abnormal warnings.

6a For CCR units provide one of the following estimates

If the catalyst circulation is changed and the octane and feed rate are held constant:

a. What is the change in the catalyst

circulation?

b. How much of the carbon-on-catalyst

change?

Note

To tune the model, it is necessary to know how each reactor affects the system during its cycle.

Theoretically, we want to know how each reactors operation changes over a cycle,

independent of the other reactors. The easiest way to estimate this is by looking at the

difference in operation between the time the reactor is taken off-line for regeneration and then

put back on-line.
