Abstract

This work introduces a model for electrochemical CO capture and solvent regeneration integrated with an Aspen Plus flowsheet. The model is built in Aspen Custom Modeler and designed to seamlessly integrate with ASPEN Plus software, allowing for comprehensive simulation of the CO capture process using an electrochemical cell to regenerate the solvent. The model includes detailed descriptions of the mass and energy balances in the electrochemical stack compartments, mass transport over the ion exchange membrane, and potential losses through the stack. The validity of the model was assessed against laboratory measurements. The model was exemplified by modeling a CO capture pilot plant for three different flue gases, from cement, magnesite, and gas-fired CHP production. The results of the integrated absorber-electrochemical system reveal key trade-offs among CO capture efficiency, energy consumption, and throughput, highlighting the performance differences across the three case studies.

摘要

这项工作介绍了一种与Aspen Plus流程集成的用于电化学二氧化碳捕集和溶剂再生的模型。该模型是在Aspen Custom Modeler中构建的，旨在与ASPEN Plus软件无缝集成，从而能够使用电化学电池再生溶剂对二氧化碳捕集过程进行全面模拟。该模型包括对电化学堆栈隔室中的质量和能量平衡、离子交换膜上的质量传输以及堆栈中的电位损失的详细描述。该模型的有效性通过与实验室测量结果进行评估。通过对来自水泥、菱镁矿和燃气热电联产生产的三种不同烟道气的二氧化碳捕集中试装置进行建模，对该模型进行了举例说明。集成吸收器-电化学系统的结果揭示了二氧化碳捕集效率、能源消耗和产量之间的关键权衡，突出了三个案例研究中的性能差异。
