Oven gas generation of plasma gasified coke oven

Abstract

This invention relates to a plasma tails treatment. Hot tails that contains steam and tar vapor from cokery is directly fed into a plasma gasifier to produce synthetic gas, reduced gas and fuel gas. Its procedure is short and easy to operate, has high heat efficiency and little pollution, and needs no catalyst, so as to eliminate toxic operation caused by catalyst decomposition.

Description

technical field

[0001] The method for the plasma gasification of coke oven raw gas in the present invention relates to a kind of coking raw gas that is assisted by plasma to produce H 2 , CO-based synthesis gas, reducing gas, and gas methods, which belong to the category of coal chemical industry and plasma chemical industry. technical background

[0002] The conventional method to deal with raw coke oven gas is: 650℃~850℃ raw coal gas is sprayed with ammonia water in the bridge pipe and gas collecting pipe to cool down to 80℃~85℃, and then cooled to 25℃~35℃ in the initial gas cooling section. A large amount of sensible heat of raw gas and a large amount of latent heat of water vapor and tar vapor are wasted. At the same time, a large amount of cooling water and ammonia are consumed. After benzene washing, desulfurization and other processes, the purified gas obtained can be used as raw material to produce synthesis gas. In each section, coking wastewater is produced, in a...
