Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of purge gas recovery, in particular to a methanol synthesis purge gas recovery device. Background Art
[0002] Methanol, also known as hydroxymethane, wood alcohol or wood spirit, is an organic compound and the simplest saturated monohydric alcohol with a chemical formula of CH3OH / CH4O. The molecular weight is 32.04 and the boiling point is 64.7°C. Methanol is known as "wood alcohol" and "wood spirit" because its main production method was once extracted from wood vinegar (one of the products of wood distillation or cracking). Modern methanol is made directly from a catalytic industrial process of carbon monoxide, carbon dioxide and hydrogen. Methanol is very light, highly volatile, colorless, flammable, and has a smell very similar to ethanol (drinking wine). But unlike ethanol, methanol is highly toxic and cannot be drunk. It is usually used as a solvent, antifreeze, fuel or denaturant ethanol, and can also be used to produce biodiesel through ester exchange reaction.
[0003] Purge gas is also called exhaust gas, tail gas, etc. It is the name of a material in chemical production. Purge gas is produced during the methanol synthesis process. The main component of the purge gas is hydrogen, with a content of about 70%. It can be used as boiler fuel and needs to be compressed and recovered. The existing recovery device has low recovery efficiency and needs to be improved. Utility Model Content
