What are the characteristics of using methanol as an absorbent? Methanol as an absorbent has the following advantages: 1. It possesses strong selective absorption properties. 2. It enables high levels of gas purification. 3. At low temperatures, methanol has low viscosity, which gives it strong absorption capabilities; moreover, its energy consumption and handling costs are low. 4. Methanol can be recycled. 5. It exhibits high thermal and chemical stability. 6. Methanol can be produced in large quantities, ensuring an abundant supply in the market.

The purification efficiency of the low-temperature methanol washing process allows the residual CO2 and H2S in the gas to be reduced to below 20 and 1 ppm respectively. Acidic gases such as CO2 and H2S have high solubility in methanol, which gives methanol a high absorption capacity. In this way, the circulation volume of methanol liquid is relatively small, thereby allowing the low-temperature methanol washing process to reduce power consumption. ) Methanol does not form bubbles, and pure methanol is non-corrosive.
