What is the purpose of introducing low-pressure nitrogen at the bottom of the fourth section of the carbon dioxide flash tower and the second section of the hydrogen sulfide concentration tower? Answer: It serves a gas-lifting function ； Introducing low-pressure nitrogen reduces the vapor pressure of CO2, increasing the driving force for the separation process and enabling CO2 in methanol to be separated at as low a temperature as possible.
Reducing the partial pressure of carbon dioxide in the gas phase causes carbon dioxide to be desorbed
It serves to perform a gas lift function； Introducing low-pressure nitrogen reduces the vapor pressure of CO2, increasing the driving force for the separation process and enabling CO2 in methanol to be separated at as low a temperature as possible.
