【Q&A Question 208】November 14, 2016: What equilibria need to be understood for the operation of a distillation column? The answer key will be available after responding; scoring is based on answering the key points. Material balance, gas-liquid phase balance, heat balance. 2016 Q&A Summary Post (updated as of November~~~~) Seeking sponsors for the “2016 HaiChuan Top 10 Members Selection Contest” http://bbs.hcbbs.com/thread-1628108-1-1.html (Source: HaiChuan Chemical Forum)
Material balance, heat balance, gas-liquid phase balance
Material balance, vapor-liquid equilibrium, and heat balance.
Three balances: mass balance, energy (heat) balance, and gas-liquid phase balance
Material balance, gas-liquid phase balance, heat balance
Material balance, temperature balance, energy conservation
Material balance, gas-liquid phase balance, heat balance
1 Material balance 2 Vapor-liquid equilibrium 3 Heat balance
①Thermal balance controls the outlet temperature of the furnace, as well as the temperatures at the top of the tower and along various side streams. ? ② The material balance requires stability of the liquid level at the bottom of the tower. ? ③ Pressure balance: ensures stable tower top pressure, a parameter that reflects vapor-liquid equilibrium.
