摘要
为进一步降低化学吸收过程中吸收剂的再生能耗,提出了基于纳米流体吸收剂的可凝气体直接抽提CO2再生工艺,制备了基于SiO2、TiO2、γ-Al2O3纳米颗粒和乙醇胺(MEA)溶液的纳米流体吸收剂,并选定戊烷、己烷和环己烷作为吹扫气,研究了基于纳米流体吸收剂的可凝气体直接抽提CO2再生性能,并对再生速率、循环负荷和再生能耗等参数进行了分析。结果表明:纳米流体吸收剂样品具备良好的稳定性;相比于传统再生方式,戊烷吹扫具有最优的再生效果,可降低超过40%的再生能耗。
To reduce the energy consumption for solvent regeneration in chemisorptions, a nanofluid-based direct non-aqueous gas stripping process was proposed for CO2 capture. Nanofluid solvents were prepared based on SiO2, TiO2 and γ-Al2O3 nanoparticles and monoethanolamine(MEA) solution, with pentane, hexane, and cyclohexane as the carrier gases, to study the CO2 desorption ability in the direct non-aqueous gas stripping process, and to analyze the regeneration rate, cycle load and related energy consumption. Results show that the nanofluid solvents prepared above are relatively stable. Compared with conventional stripping processes, optimum regeneration effects could be obtained with pentane as the carrier gas, when the regeneration energy could be lowered by more than 40%.
