Backup File

Save this property estimation as a backup file (.bkp) that you can

import into a flowsheet simulation that uses thiazole.

1 Select File | Save As

2 In the Save As dialog box, select Aspen Plus Backup Files in

the Save as type field.

3 In the File Name field, enter thiazole.

4 Click Save.

An Aspen Plus dialog box appears warning you that you will not

be able to start new calculations from previous results and suggests

saving the file as an Aspen Plus document file (.apw).

5 Click No since you only need the backup file.

Next, try using your backup file to import thiazole data into

flash.apw.

Run the Flash simulation with methanol, water, and thiazole in

Stream 1. Follow these steps.

1 Open Flash.apw from your working folder and click Yes to

close the thiazole estimation.

2 Click File | Import and select thiazole.bkp and click Open.

Note: You cannot import an Aspen Plus document file (.apw) into

another simulation.

3 An Information dialog box appears. Click OK.

The flowsheet disappears since the thiazole backup file is a

properties estimation. However, the flowsheet data from

Flash.apw is still available.

4 Press F8 to open the Data Browser.

5 In the Data Browser menu tree expand the Setup folder and

click Specifications.

The Setup | Specifications | Global sheet appears.

6 In the Global Settings area, change the run type to Flowsheet.

The flowsheet and stream and block input data from Flash.apw are

now accessible.

7 In the Data Browser menu tree, click Properties | Estimation |

Input and then select Do not estimate any parameters since

the thiazole parameters have already been estimated.

8 In the Data Browser menu tree, click Streams | 1 | Input and

then in the Composition area of the Specifications sheet, type

50 for the mole flow of the component thiazole which is now

listed along with methanol and water.

9 Press F5 to run the simulation with thiazole in Stream 1.
