This post was last edited by Benbenxuan on 2011-2-24 08:47. Dear everyone~! Does anyone have a handbook of organic properties handy? Please help me find out which group C compound it is that condenses at around 37°C under a pressure of 0.35 MPa~! I’m away from home and don’t have any documents with me. . . . . .
After a preliminary check, it should be around C6
Sorry, I misread it. The pure component that can condense at this pressure and temperature should be C4; components smaller than C4 (as pure components) basically cannot condense.
I would like to ask the colleague on the 3rd floor: which property handbook did you use? I sometimes want to look things up as well, but I don’t have any relevant materials available. Thank you!
Reply to 4# Li Xiaoxiao Pippi: I used ASPEN for the calculations, simulating it with a flash tank. Define a C4 component such that its flash output at 0.35 MPa and 37 degrees Celsius is a pure liquid phase, whereas the flash output of the pure C3 component is a pure gas phase. If it is a mixture, the issue of gas-phase partial pressures comes into play; that is, Dalton’s law of partial pressures and Raoult’s law must be applied. The situation becomes more complex in such cases, and ASPEN can be used for simulation.
Thank you, gujiaming1985 ~! The test results are in. It’s mainly the C4 component~!
