To increase the popularity of the purified area, a \"One Question per Day\" campaign was launched to foster an active atmosphere for technical exchanges while providing members with certain financial rewards. (Fellow sailors, if you have any good questions, feel free to send them to me; let’s work together on them.) 【Daily Question】 (Fill in the blank) In a low-temperature methanol washing unit, under certain temperature and pressure conditions, when using methanol to remove acidic gases such as CO2 and H2S from cold shift gas, which of these gases is easier to remove, or in other words, which one has a higher solubility in methanol? ( ) Reply with your answer in the comments; participating in the quiz earns you +2 wealth points. If you answer all questions correctly, you’ll receive an additional +3 to +8 wealth points. Those who provide thorough analysis and explanations for the questions (or include detailed calculation processes) will receive extra wealth points as a reward. If your answer is correct and your analysis and explanation are accurate, it will be marked as the best reply (or the best assistance). Feel free to answer the questions. H2S
H2S has a higher solubility in methanol; its solubility in methanol is much greater than that of CO2
In the low-temperature methanol washing unit, under certain temperature and pressure conditions, when using methanol to remove the acidic gases CO2 and H2S from cold shift gas, which one is easier to remove, or in other words, which one has a higher solubility in methanol? (H2S)
The solubility of H2S at -50°C is 6 times that of CO2
