【Q&A Question 310】November 24, 2017: What are the three key equilibria that need to be understood in the operation of a distillation column? In the operation of a distillation tower, it is necessary to understand material balance, gas-liquid phase balance, and heat balance. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) For management purposes, if you need to view content from a few days ago, please go through the summary post below. 2017 Q&A Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html (Source: Haichuan Chemical Industry Forum)

Material balance, gas-liquid phase balance, and heat balance
The operation of a distillation column requires an understanding of material balance, gas-liquid phase equilibrium, and heat balance. (1) Heat balance: The balance between the heat entering the tower and the heat leaving it. (2) Material balance: The balance between the feed rate to the tower and the product withdrawal rate. (3) Gas-liquid phase equilibrium refers to a state in which gas and liquid phases coexist in a system, with mass transfer occurring between the two phases, resulting in constant temperature and pressure in the system and unchanged compositions of each phase.
