Abstract
本文根据焦化烟道气实际数据,应用流程模拟软件Aspen Plus模拟分析了MEA吸收剂以及MEA和空间位阻胺AMP混合吸收剂捕集烟道气中C02的吸收解吸效果。结果表明,混合胺浓度30wt%(摩尔比MEA:AMP=1:1)吸收剂的吸收效果较好,为了进一步考察该种配比混合胺吸收剂的吸收、解吸特性,对其进行了灵敏度分析,并选取了25wt%MEA为基准吸收剂,对比分析了进料温度、解吸塔再沸器热负荷和解吸塔压力对吸收解吸效果的影响,当吸收剂进料温度40℃时,单一MEA吸收剂吸收C02效率86.8%,混合胺的吸收率89.6%;2种吸收剂达到55%的解吸率,单一MEA吸收剂工艺再沸器热负荷为4500kW,混合胺吸收剂工艺再沸器热负荷为3000kW;当解吸塔压力1.5bar时,单一MEA吸收剂对C02解吸率52.4%,混合胺吸收剂的解吸率55.8%,由对比结果得出混合胺(摩尔比MEA:AMP=1:1)的吸收、解吸效果均优于单一25wt%MEA吸收剂
