Where and why are the purge gas emissions from the synthesis system released? Answer: Location: After the methanol separator. Reason: This location has the highest concentration of inert gas in the circulation system; venting here can effectively prevent excessive loss of the unreacted active components CO, CO2, and H2.
A portion of the gas phase from the separator is discharged as vent gas, while another portion is used as recycle gas to maintain an appropriate proportion of inert gases in the syngas.

Location: After the methanol separator. Reason: The gas exiting the separator is the residual gas remaining after the reaction, and most of the methanol has been separated out; thus, this location has the highest concentration of inert gas in the circulation system. Venting at this point can effectively prevent excessive loss of the unreacted components CO, CO2, and H2. It also facilitates the stable operation of the system.
