What are the common methods used to remove organic amines from methanol in coal chemical industry methanol production projects?
Thread Content
In coal-to-oil methanol projects, methanol contains a small amount of organic amines; what methods are generally used to remove them?
Organic amines are purified by absorption before the synthesis tower, while distillation is used in the distillation section

A resin specifically designed for removing organic amines can be used; the resin model is Amberlyst 15 Wet. Methanol produced domestically is mainly made from coal, so it contains less organic amine. Abroad, natural gas-based streams are more common, as are organic amines; these also constitute an important factor affecting the quality of AA-grade methanol. Therefore, purification is generally carried out after distillation using resins of specific types.
Currently, Romhus resin is being used everywhere; it seems that there is still room for domestic resins to compete in this market. Thank you!
