低温甲醇洗探讨？ - the rectisol process is used in order to remove impurities from the synthetic natural gas . the impurities that are removed from the gas in this process include co2, naphtha, and varying sulfur compounds. these impurities are removed through a series of washes and pressure changes. the basic idea behind the removal process is that the solubility of each impurity varies in a methanol wash. the graph to the right, obtained from the lurgi web site, shows the variation in absorption coefficient, α, for each substance. the actual process of absorbing each component and subsequently cleaning methanol is a very complex and energy intensive process. 低温甲醇洗工艺用于脱除合成天然气中的杂质。从合成气中脱除的杂质包括co2，石脑油及各种硫成分。通过一系列的洗涤和压力变化脱除这些杂质。净化工艺的基本思路是在甲醇洗涤液中各杂质的溶解度的差异。右边一张来自鲁奇网站的图表显示了每一种物质的吸收系数，α的变化。实际上，每一种组分的吸收及吸收过后的甲醇净化再生都是非常复杂，能量密集的工艺。 低温甲醇洗工艺用于脱除合成天然气中的杂质，这种说法对，在低温甲醇洗净化的气体要用于甲烷化合成的。查看更多
