A mixture stream containing 50kmol of sorbitol, 750kmol of water and 6000kmol of hydrogen leaves reactor at 145C and 70barg. 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 50100C and the pressure of 50barg. 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 (b) taking the system as a real system (10 marks) 2. draw a diagram to show the molar faction of hydrogen and sorbitol varying with temperature. (5 marks) Assume that the thermodynamic equilibrium is the only control factor for the separation. State any other assumptions used in your calculation
