Benzene Flowsheet Conditions Workshop
• Objective: Add the process and feed stream conditions to aflowsheet.
– Starting with the flowsheet created in the Benzene FlowsheetDefinition Workshop (saved as BENZENE.BKP), add the process andfeed stream conditions as shown on the next page.
• Questions:1. What is the heat duty of the block “COOL”? _________2. What is the temperature in the second flash block “FL2”? _________
Note: Answers for all of the workshops are located in the very back of
the course notes in Appendix C.
