摘要
近年来,环境问题和能源危机日益突出。煤炭储量丰富、价格低廉,但煤炭燃烧后产生的硫化物污染问题十分严重,因此人们开发了各种脱硫工艺。介绍了当今广泛使用的脱硫工艺。煤气脱硫方法主要有干法脱硫和湿法脱硫。同时介绍了T.H法脱硫工艺、F.R法脱硫工艺和P.D.S+栲胶脱硫脱氰技术三种典型的湿法脱硫工艺。
In recent years,the environmental problems and energy crisis have become increasingly prominent.Coal has abundant reserves and relatively low price.However,gas desulfurization is a key process in coal combustion.Various desulfurization processes have been developed.The widely used desulfurization technology was introduced.The main methods of gas desulfurization were dry desulfurization and wet desulfurization.At the same time,three typical wet desulfurization processes,i.e.T.H desulfurization process,F.R desulfurization process and F.D.S+tannin extract desulfurization and decyanation technology,were introduced.
