两个吸收/汽提工艺配置，即一个新的热泵蒸馏与分流过程（HPDSFP）和分流过程与塔顶换热器，进行了评估，以最大限度地减少能源消耗的CO2捕获从300 MW的电厂烟气使用30重量%的水单乙醇胺（MEA）。它们的性能进行了比较，与基线MEA过程。采用ProMax3.2程序对所有过程进行了模拟。采用ProMax软件SWEET动力学模型，对MEA-CO2体系吸收/再生过程中的放热可逆化学反应进行了模拟。进行了敏感性分析，以评估关键参数（如溶剂循环速率和贫CO2负荷）对能量需求的影响。在总当量功方面，对HPDSFP、具有塔顶换热器的分流进料工艺和基线工艺进行了比较。在本工作中，HPDSFP，分流工艺和基线工艺的最小总当量功分别为0.37，0.50和0.56 GJ/t CO2。模拟结果表明，新的工艺配置HPDSFP和分流工艺与塔顶换热器导致了大的改善，总当量功分别减少了10.7%和33.9%。
Two absorption/stripping process configurations, namely a new heat pump distillation with split flow process (HPDSFP) and split flow process with an overhead heat exchanger, were evaluated to minimize the energy consumption of CO2capture from a 300 MW power plant flue gas using 30 wt% aqueous monoethanolamine (MEA). Their performances were compared with that of the baseline MEA process. All the processes were simulated using ProMax3.2 program. A rigorous model built onSWEETkinetics of ProMax was used to simulate the exothermic, reversible chemical reactions in MEA-CO2system in the absorption/regeneration process. Sensitivity analyses were performed to evaluate the effects of key parameters (e.g. solvent circulation rate and lean CO2loading) on energy requirement. Comparison of the HPDSFP, the split feed process with an overhead heat exchanger and the baseline process was conducted in terms of total equivalent work. In this work, the minimal total equivalent works of HPDSFP, the split flow process and baseline process were 0.37, 0.50 and 0.56 GJ/t CO2, respectively. The simulation results showed that the new process configuration HPDSFP and split flow process with an overhead heat exchanger resulted in large improvements with reductions of total equivalent work by 10.7% and 33.9%, respectively.
