Many people may be involved in creating and maintaining a flowsheet. For instance, the FCC portion of a refinery wide flowsheet may be recalibrated by the FCC engineer, while another engineer does planning studies with the flowsheet. Do you want everyone to have access to the most updated model and that they work on the same basis? The Petro-SIM database functionality can help.
Petro-SIM’s Database functionality can provide an easy way to maintain flowsheets among multiple users. Petro-SIM can directly connect to a database which has the capability to hold all the stream and unit information. Any single object or combination of them can be exported to and imported from the database.
- Using the Sample file icon on the toolbar open the file Furnace.ksc.
Under the Data menu, click on the Connections. This opens up the Database Connection window. Make sure the SQlite database is selected. The path defined in the screenshot below is for illustration purpose only. In order to share with your colleagues you will need to choose a database on your network to which everyone working on the same flowsheet has access
Click on Connect button. Note the Database Connection drop down menu which allows you to customise your default connections.
- Right click on the furnace, select Database, then Export to Database.
- Type in a desired Collection Name, and click on Save to Database. Remember a detailed description for the object will be very handy, keeping everyone informed about the changes.
- Open a new case. Right click on any part of the PFD. Select Database, then Import Objects from Database. Select Furnace from the object list. The furnace should now appear on the PFD. Note the furnace will contain its configuration data only, you will need to connect it with a feed stream.
- Double-click on the furnace. On the Design tab Connections page change the Firebox Efficiency from 75 to 80. Allow the simulation to run and converge.
- Under the Data menu, click on the Update icon.
- Update the database items by selecting Scan for All Available Updates and My Changes. Select the change that you want transferred and click on Sync.
- Open the file Furnace.ksc again. You will see that the firebox efficiency is still at 75.
Your flowsheets can also be configured to automatically scan for updates to models in the database e.g. when your FCC engineer has updated the FCC calibration, your flowsheet will let you know and ask if you want to update your model. We will show you how to do this in a future tip.
- As before, click the Update option under Data menu. Then select Scan for All Available Updates and My Changes. Finally, when you have selected the desired modification click on Sync. From the data categories select all data and click on OK. Allow the unit to run, and converge. The efficiency should now be 80 as well.
