在该付款人中，对二氧化碳去除和液化系统进行了建模，该系统将二氧化碳从传统发电厂的烟气中分离出来。该系统基于胺化学吸收汽提系统，然后是液化装置，用于处理去除的二氧化碳以进行运输和储存。介绍了主要参数对吸收塔和汽提塔的影响。该模型的主要约束条件是捕获效率为 90%，并且使用胺含量按重量计最大为 30% 的水溶液。本研究的目标是在将其集成到化石燃料发电厂时，以最低的能量需求去除二氧化碳。将模拟结果与可行性研究和现有电厂的实验和文献数据进行比较。连接去除系统的发电厂是一座 320 MW 蒸汽发电厂，配有蒸汽再热器和 8 个给水加热器。考虑了两种不同的化石燃料：煤炭和天然气。还研究了在发电厂整合二氧化碳去除系统所需的改造效果，估算了去除和液化系统的资本成本，并计算了其对发电成本的影响。 (C) 1999 Elsevier Science Ltd. 保留所有权利。
In this payer, a carbon dioxide removal and liquefaction system, which separates carbon dioxide from the flue gases of conventional power plants, was modelled. The system is based on an amine chemical absorption stripping system, followed by a liquefaction unit to treat the removed CO2 for transportation and storage. The effect of the main parameters on the absorption and stripping columns is presented. The main constraints set for the model are a capture efficiency of 90% and the use of an aqueous solution with a maximum 30% amine content by weight. The goal of this study is to remove the CO2 with minimum energy requirements for the process when it is integrated in a fossil fuel fired power plant. Results of the simulation are compared to experimental and literature data from feasibility studies and existing plants.The power plant to which the removal system is connected is a 320 MW steam power plant with steam reheat and 8 feedwater heaters. Two different fossil fuels were considered: coal and natural gas. The effect of the modifications necessary to integrate the CO2 removal system in the power plant is also studied,The capital cost of the removal and liquefaction system is estimated, and its influence on the cost of generated electricity is calculated.
