Let’s discuss the most commonly used gas purification methods in current production
Thread Content
There are many purification methods, but those that have been tested in production can be discussed to see which ones are more practical
Low-temperature methanol washing is used for cogeneration, while MDEA is used for IGCC – but this isn’t absolute! ! ! ! ! ! !
1. Pressure swing adsorption decarbonization 2. MDEA decarbonization 3. Low-temperature methanol washing for decarbonization and desulfurization, coupled with Claus sulfur recovery 4. “888” tannin desulfurization
