discuss: The material selection of low-temperature methanol washing absorption tower trays of various companies is:: Carbon steel or stainless steel? What are the pros and cons of each?

From the aspects of corrosion prevention and service life, it is safer to choose stainless steel.

Considering long-term operation, stainless steel is preferred. Ours is made of stainless steel. Now the internal parts of the distillation tower of the methanol distillation system are made of stainless steel. The corrosiveness of crude methanol is much lower than that of the low-temperature methanol washing medium. I have seen photos of severely corroded methanol-water separation tower trays from other manufacturers (note that the material is carbon steel).
