Selection of property methods for PRO/II hydrocarbon cryogenic separation
Thread Content
This post was last edited by longkui1990 on 2013-1-14 09:00. For the deep-cold separation of hydrocarbons such as methane, ethane, propane, ethylene, propylene, and butylene, what property evaluation method is appropriate when using PRO/II software to simulate distillation columns?
In the software examples, the SRK thermodynamic method is used, while the LK method is employed to calculate enthalpy values.
SRK or PR, as well as their improved versions, are all quite suitable
I think PR would be better; SRK works too, but it’s not as good as PR.
Use the PR or SRK equations; PRSV can also be used
What processes are PR-BM used in?
Hello everyone, I would like to ask: For the formation of crystalline solids in cryogenic conditions, what thermal methods should be used? Which thermodynamic method is used for liquid-solid separation?
