What thermodynamic equation is used for the vapor-liquid equilibrium simulation of silane purification?
Thread Content
The components in this material are SiH4, Si2H6, PH3, AsH3, and NH3. What thermodynamic equations and calculation methods should be used to determine the vapor-liquid equilibrium of this system and to purify SiH4 using a distillation column? Please give me some advice. Thank you!
It seems that really no one has done it; the foreign technologies are kept secret. To develop our own technologies and strengthen our chemical industry, we have to rely on self-development
If there are data from the production process, several common methods can be used for verification.
I used NRTL-RK in similar distillation simulations. However, since the purification of chlorosilanes requires very high purity and involves precision distillation with a high reflux ratio, several physical property-based methods were tried, but with little difference.
