Despite rising concern with climate change, carbon capture is yet to be implemented widely in the industry due to its size and cost. The rotating packed bed (RPB), a high gravity technology process, has been suggested to intensify the conventional packed bed. In this study, rigorous models of the RPB absorber and stripper for carbon capture are developed and implemented in the commercial simulator of gPROMS. The developed process models are validated with published steady-state experimental data and the entire carbon capture process comprising the RPB absorber, the RPB stripper, and other process units with solvent recycle is simulated. Initial designs of the rotating packed beds are suggested considering the flooding limit and capture rate. Then the steady-state optimal operation conditions minimizing the total energy of the MEA process with the intensified absorber and stripper are found and their behaviors are analyzed.

用于基于MEA的碳捕集的旋转填充床(RPB)吸收器和汽提塔的建模,仿真和优化

尽管人们越来越关注气候变化,但由于碳捕集的规模和成本,其在碳捕集中的应用尚待广泛应用。旋转填料床(RPB)是一种高重力技术工艺,已被建议加强常规填料床。在这项研究中,用于碳捕集的RPB吸收器和汽提塔的严格模型已在gPROMS的商业模拟器中开发和实现。已开发的过程模型已用已发布的稳态实验数据进行了验证,并且模拟了整个碳捕获过程,包括RPB吸收器,RPB汽提塔和其他带有溶剂循环的过程单元。建议对旋转填充床进行初步设计,并考虑进水极限和捕获率。
