Benfield工艺技术进展

Technological Advances in Benfield Process

热钾碱法(Benfield)工艺是合成气脱除CO2最主要和应用最多的方法之一,占有十分重要的地位。在简要叙述工艺发展历程和基本原理的基础上,着重介绍和评述该工艺的3种主要流程,即H ipure工艺、LoHeat工艺和PSB工艺,及近年来所取得的技术进展。

The Benfield process is one of the most important and most used methods for the removal of CO2 from syngas and occupies a dominant place, On the basis of a brief description of the course of its development and its fundamental principle, three main flowsheets of the process are emphatically presented and reviewed, viz. , Hipure, LoHeat and PSB as well as the technological advances made in recent years.
