Coke oven gas finely-purifying process for multiple combustion engines

Abstract

The invention discloses a coke oven gas finely-purifying process for multiple combustion engines. The coke oven gas finely-purifying process for multiple combustion engines comprises the following steps: a, coarsely removing coke oven gas by using a coarsely removing system; b, pressurizing the coarsely-removed coke oven gas by using a pressurizing system; and c, finely removing the pressurized coke oven gas by using at least two-stages of finely removing systems, wherein the coke oven gas which is finely removed by a former-stage finely removing system is divided into two parts; one part of the coke oven gas is sent into a combustion engine matched with the coke oven gas; the other part of the coke oven gas is sent into a next-stage finely removing system of the at least two-stages of finely removing systems; all the coke oven gas which is finely removed by a last-stage finely removing system is sent into a combustion engine matched with the coke oven gas. In the coke oven gas finely-purifying process for multiple combustion engines, the coke oven gas is coarsely removed and then finely removed by stage, so that the coke oven gas purified by the process has different grades; and the coke oven gas at different grades enters combustion engines matched with the coke oven gas and is combusted, so that requirements of different combustion engines can be met.

Description

technical field [0001] The invention relates to the field of coke oven gas purification treatment, in particular to a coke oven gas purification process. Background technique [0002] As a by-product of coking, coke oven gas is widely used in power generation projects in the metallurgical industry due to its high calorific value. Coke oven gas still contains some impurities (tar, phenol, cyanide, benzene, naphthalene, etc.) after the initial purification of coking oven gas. If the coke oven gas is not purified twice, direct combustion and release will cause pollution to the atmosphere and the environment. form SO 2 At the same time, chemical substances such as benzene and naphthalene are also very harmful to the human body, and tar and the like also seriously pollute the environment. At the same time, the impurities in the coke oven gas will block the burner of the gas turbine, corrode the heating part of the gas turbine, cause the gas turbine to be shut down frequently fo...

AI Technical Summary

Problems solved by technology

In reality, factories often use coke oven gas with the same purification quality for different gas turbines; however, the quality requirements of coke oven gas for different gas turbines are different, which leads to The coke oven gas produced cannot meet the requirements of different gas turbines
