Description

Technical Field

[0002] Methanol, also known as hydroxymethane, wood alcohol, or wood spirits, is an organic compound and the simplest saturated monohydric alcohol, with the chemical formula CH3OH / CH4O. It has a molecular weight of 32.04 and a boiling point of 64.7℃. Methanol is primarily produced through extraction from wood vinegar (a product of wood distillation or cracking). Modern methanol is manufactured directly from carbon monoxide, carbon dioxide, and hydrogen in an industrial process involving catalysis. Methanol is light, highly volatile, colorless, flammable, and has an odor very similar to ethanol (a beverage). Therefore, methanol recovery is necessary in methanol separation processes.

However, the heating temperature of the methanol mixture cannot be precisely controlled, resulting in a large amount of water vapor in the methanol vapor. After liquefaction, this leads to a high water content in the methanol, resulting in low methanol purity and affecting its usability after recovery. Utility Model Content
