Abstract

This review provides an analysis of modern process technologies for carbon dioxide removal from various gas mixtures (such as natural gas or hydrocarbon conversion gases in ammonia and syngas production facilities), as well as from flue gases generated during the combustion of carbon-containing feedstocks in power plants. The review also discusses various approaches to improve absorption/desorption processes, both in terms of extending the range of practicable amine solvents and the prospects for the implementation of a new equipment type, namely membrane contactors based on hollow fiber membranes or ceramic tubular elements. Finally, the paper describes a process configuration for the decarbonation of rich amine solvents at ≤90°C using 12% monoethanolamine (MEA) solutions to prevent the solvent from thermo-oxidative degradation.

净化混合气体以去除二氧化碳的方法的优化(综述)

摘要

这篇综述对从各种气体混合物(例如氨和合成气生产设施中的天然气或碳氢化合物转化气体)以及含碳原料燃烧过程中产生的烟道气中除去二氧化碳的现代工艺技术进行了分析。发电厂。这篇综述还讨论了各种改善吸收/解吸过程的方法,既包括扩大实用的胺类溶剂的范围,也包括实现新型设备的前景,即基于中空纤维膜或陶瓷管状元件的膜接触器。最后,本文描述了使用12%单乙醇胺(MEA)溶液在≤90°C下对富胺溶剂进行脱碳的工艺配置,以防止溶剂热氧化降解。
