Dear Sir/Madam
The vent gas (most of nitrogen, cyclohexane, trace water, and trace ammonia) (flow=12674kg/hr, Tin=70C) entering the shell side of exchanger, and
, the vapor (flow=8880kg/hr, Tout=15C, Pout=0.1barg) and liquid (flow=3794kg/hr).
The non condensable gas is N2 (flow=118kg/hr).
Having said that, the heat curve also provided, At 0.1barg, temp=15C, vapor fraction=0.8598, viscosity of vapor=0.0157, viscosity of liquid=1.0553, density of vapor=1.495, density of liquid=781.7
I hope to estimate the non condensible molar fraction of the vent gas, but total molar weight is unknown. I tried to use Pro\II to simulate to get the composition this vent gas, but it seems not work well because the inlet composition is not given.
Could any pro here kindly tell me how to simulate this simple case?
Thank you so much.
