论整体煤气化联合循环（IGCC）中煤气净化技术的选择

On the Choice of Gas Clearing Technology in Integrated Coal Gasification Combined Cycles (I. G. C. C).

粗煤气中含有的粉尘、Ｈ２Ｓ、ＣＯＳ、ＮＨ３、ＨＣｌ及气态碱金属等污染物不仅污染环境，而且严重磨损和磨蚀燃气轮机的叶片。从环保和设备的要求出发，必须对进入燃气轮机的煤气净化。作者论述了煤气化联合循环发电（ＩＧＣＣ）中煤气化的要求和各种常温净化技术的主要特点，并针对ＩＧＣＣ示范系统提出了常温净化工艺的选择方案，阐述了煤气高温净化的研究现状和发展方向。

Abstract Not only do pollutants, like dust particles, H2S, COS, NH3, HCl and gaseous state alkaline metals, as contained in coarse coal gas, foul the environment, but they erode and abrade gas turbine buckets in addition. From the point of view of environmental and equipment protection requirements, it is compelling to cleanse the coal gas before it enters the gas turbine. The author discusses the gasification reguirements of coal gas in power generation with integrated coal gasification combined cycles, the main features of various cleaning technologies under ambient temperature conditions, as well as the proper choice ofgas cleaning for an integrated coal gasification combined cycle demonstrationsystem. The paper delineates the status quo and trends of researche on high temperature cleaning methods of coal gas.
