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 to effect gas lift ； 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
It serves to perform a stripping function； Introducing low-pressure nitrogen reduces the vapor pressure of CO2, increasing the driving force for the desorption process and enabling CO2 in methanol to be desorbed at as low a temperature as possible.

It serves a stripping function; by introducing low-pressure nitrogen, the vapor pressure of CO2 is reduced, thereby increasing the driving force for the separation process and allowing CO2 to be separated from methanol at as low a temperature as possible.
