Question

Set-up an input/output structure of the flowsheet showing the flow of all materials into and out of the black - box representing the plant in kmole/h.
Estimate the economic potential of this process in $/year

The design information for cyclohexane process provided is as follows:
Production rate: 80000 ton/year of cyclohexane
Reaction: cyclohexane is produced from benzene and hydrogen by the following reaction:
C6H6 + 3H2 → C6H12
Reaction conditions: Gas phase reaction, nickel catalyst, reactor temperature 160-220 C
Reactor pressure: 32 bar, hydrogen to benzene mole ratio range 3:1
Raw materials: Hydrogen containing 25 mole% methane and pure benzene
There are 330 working day/year. The prices of chemicals are shown in Table Q1
