采用传输膜冷凝器（TMC）对单乙醇胺（MEA）、二乙醇胺（DEA）、哌嗪（PZ）和甘氨酸钾（PG）富分流改进型碳捕集工艺中的热汽提气余热进行回收。220 h试验表明，TMC具有良好的余热回收性能稳定性。基于PZ的TMC改进的富分流工艺（即，PZ-case）实现了最高的废热回收性能，其次是PG-case、MEA-case和DEA-case。在废热回收过程中，热通量和水通量之间存在很强的线性关系。考虑了三种情景，以比较4种情况下的CO2捕获成本节约。当TMC面积固定时，即富气分流改造的额外投资相同时，PZ方案获得的CO2捕集成本节约最高（6.40美元/t-CO2），其次是PG方案、MEA方案和DEA方案。当需要600 kJ/kg-CO2的固定废热回收性能来获得相同的收益时，在富分流改造后，PZ-和PG-情况获得了相同的CO2捕获成本节省4.22美元/t-CO2。此外，当再沸器负荷降低潜力为15%时，PG-情况实现了最大的CO2捕集成本节约（$4.56/t-CO2）。
In this study, the waste heat from the hot stripping gas was recovered by adopting the transport membrane condenser (TMC) in the monoethanolamine (MEA)-, diethanolamine (DEA)-, piperazine (PZ)- and potassium glycinate (PG)-based rich-split modified carbon capture processes. A 220-h test showed that TMC can exhibit a good stability on the waste heat recovery performance. The PZ-based TMC-modified rich-split process (i.e., PZ-case) achieved a highest waste heat recovery performance, followed by the PG-case, MEA-case and DEA-case. A strong linear relationship between the heat and water fluxes was observed during the waste heat recovery. Three scenarios were considered for comparing the CO2capture cost savings of 4 cases. When the TMC area was fixed meaning the same additional investment of rich-split modification, PZ-case gained the highest CO2capture cost saving ($6.40/t-CO2), followed by PG-, MEA- and DEA-case. When a fixed waste heat recovery performance of 600 kJ/kg-CO2was required for obtaining the same revenue after rich-split modification, PZ- and PG-case obtained the same CO2capture cost saving of $4.22/t-CO2. Moreover, when the reboiler duty reduction potential was aimed at 15%, PG-case achieved the maximum CO2capture cost saving ($4.56/t-CO2).
