燃煤锅炉烟道气二氧化碳回收装置设计应用与探讨

Application and Discussion on the Design of Carbon Dioxide Recovery Device from the Coal-fired Boiler Flue Gases

本文重点讲述燃煤锅炉烟道气中二氧化碳的回收利用工艺的选择,一乙醇胺(MEA)法回收烟道气中二氧化碳的基本原理和工艺流程以及回收过程中的难点,通过对回收装置设计与合理选用,克服回收工艺方法中的缺陷,达到能实际应用的目的。

This paper mainly illustrates the recycle technical selection of carbon dioxide recovery device from the coal-fired boiler flue gases. Using the method of monoethanolamine （MEA） to recycle carbon dioxide from flue gases has some difficulties, and the fundamental and technological process have been analyzed. According to the design of recovery device and reasonable selection, the drawbacks in the recycle method have been overcome and eventually achieve the practical application.
