Why is CO2-enriched methanol used as the absorbent in hydrogen sulfide absorption towers? Answer: 1. Based on the selective absorbency of methanol, H2S has a greater solubility in methanol than CO2. 2. Using CO2-enriched methanol as the absorbent for desulfurization prevents a significant temperature rise in the hydrogen sulfide absorption tower due to the large amount of heat generated by the absorption of CO2, which facilitates the absorption of H2S and CoS.

1. The selective absorption property of methanol. 2. It prevents a large temperature rise within the tower due to the release of significant heat when CO2 is absorbed, which facilitates the absorption of H2S and CoS.
1. Based on the selective absorbability of methanol, H2S has a greater solubility in methanol than CO2. 2. Using methanol enriched with CO2 as an absorbent for desulfurization prevents excessive heat generation resulting from the absorption of CO2 in the hydrogen sulfide absorption tower, which could lead to an increase in temperature. ’
1. Based on the selective absorbability of methanol, H2S has a greater solubility in methanol than CO2. 2. Using CO2-enriched methanol as the absorbent for desulfurization prevents a significant temperature rise in the hydrogen sulfide absorption tower, which would occur due to the large amount of heat generated by the absorption of CO2; this facilitates the absorption of H2S and CoS
