在煤化工中，低温甲醇洗技术脱除合成气中的酸性气体面临冷量消耗大的问题。在这项工作中，提出了一种室温下从合成气中脱除酸性气体的方法。采用离子液体作为物理溶剂。对离子液体的研究表明，[bmim][Tf2N]是一种合适的离子液体，可以实现H2S和CO2的同时脱除，使过程更加简单。对该工艺进行了建模和模拟，结果表明，该工艺具有良好的性能，CO2和H2S的去除率分别达到97.6%和95.3%。灵敏度分析是研究操作条件对过程性能的影响，为研究人员进行决策提供基础数据。与低温甲醇洗工艺相比，离子液体工艺具有在室温下操作的优点，节省了大量的制冷能耗。同时，离子液体在回收过程中损失率低，能耗低。结果表明，离子液体是一种很好的替代冷甲醇的CO2捕集和H2S脱除的大规模催化剂。
In coal chemical industry, sour gas removal from syngas using Rectisol technology is facing the problem of large cold energy consumption. In this work, a room-temperature process for sour gas removal from syngas is proposed. Ionic liquid is used as physical solvent. The study of ionic liquids shows that [bmim][Tf2N] is a suitable IL that can achieve the simultaneous removal of H2S and CO2that makes the process more simple. The process is modeled and simulated and the results show a good performance which CO2and H2S removal rate reaches 97.6% and 95.3%, respectively. Sensitivity analysis is carried out to study the influence of operating conditions on process performance, it provides the basic data for researchers to make decisions. Compared with the Rectisol process, the ionic liquid process has the advantage of operation at room temperature which saves large amount of energy used for refrigeration. Meanwhile, ionic liquid has low loss ration and low energy consumption in recovery. The comparison shows that ionic liquid is a good alternative to the cold methanol for CO2capture and H2S removal on a large scale.
