I have 10,000 cubic meters of gas at a temperature of 200°C; it is composed of 95% air and 5% N-methylpyrrolidone. Now the temperature is being reduced to 65°C, causing partial condensation. I used the heater function in Aspen to calculate the amount of condensation, but I’m not sure how to determine the amount of N-methylpyrrolidone that condenses
Look directly at the results for the heater
Check in STREAM: the proportion of condensed material in the feed
The simplest approach is to feed the mixture into a vapor-liquid separator at a specific temperature and pressure (which serves both for condensation and separation); the liquid phase resulting from this process contains the amount of material that has been condensed, and the NMP present in this liquid phase is the key component that has been cooled down.
It’s one approach, but I’m not sure if Vapor frac refers to the molar fraction
Vapor frac is the gas fraction; you need to find the molar flow rate of the condensing material in both the inlet STREAM and the condensate STREAM, and then calculate the proportion of the condensed amount
Is it the load? Condensation volume? I don’t understand it
The load allows the results to be seen directly elsewhere
