a reactor at 145 °C and 70 barg. It is then cooled and sent to a flash to be separated into a gas stream
of hydrogen for recycle back to the reactor and an aqueous sorbitol solution stream. The flask is to be
operated at a temperature in the range of 50-100 °C and the pressure of 50 barg. You are asked to
1. calculate the composition of the gas and aqueous sorbitol streams in the temperature range
interested by
(a) taking the system as an ideal system
taking the system as a real system
(b)
(10 marks)/nAssume that the thermodynamic equilibrium is the only control factor for the separation.
State any other assumptions used in your calculation.
