In methanol synthesis, why is it necessary to relieve pressure and perform purging when the synthesis tower is shut down for an extended period of time? Also, the parking and pressure relief time can be 12 hours or 24 hours – how is this determined?

This is the gasification version; you’d better go and ask in the methanol synthesis section
Prevent gases from reacting within the system, as the by-products generated can have a significant impact on the catalyst’s lifespan
Reply to 1# scg311: If the parking time is too long, CO2 in the methanol synthesis gas will react with copper in the methanol synthesis catalyst to form basic copper carbonate. An excessive amount of this substance can reduce the catalyst’s activity; this issue is addressed in the instructions for foreign methanol synthesis catalysts.
