コークス炉石炭ガス脱硫再生塔排ガス処理プロセス及びシステム

Japanese Patent JP7174163

B2

Disclosed are a process and a system for treating a tail gas from a desulfurization regeneration tower (1) for coke oven coal gas. After an enriched desulfurization liquid in the desulfurization regeneration tower (1) is oxidized and regenerated, a large amount of oxidizing gas escapes from a gas phase outlet at the top of the tower and enters a gas-liquid separator (8); with a mist-capturing layer (10) being provided at the top of the gas-liquid separator (8), mist droplets captured by the mist-capturing layer (10) are discharged from a liquid phase outlet at the bottom of the gas-liquid separator (8), pressurized by means of a pump (11) and then returned to the desulfurization regeneration tower (1); a separated gas phase, which is a circulating oxidizing gas, escapes from a gas phase outlet at the top of the gas-liquid separator (8) and enters a gas-pressurizing device (9); and the circulating oxidizing gas is first pressurized by the gas-pressurizing device (9) and then mixed with a supplementary oxidizing gas and further mixed with the enriched desulfurization liquid, and then enters the bottom of the desulfurization regeneration tower (1). The oxidizing gas used for the oxidation regeneration of the enriched desulfurization liquid is recycled, so that the system does not realize emission gas generation, thereby finally achieving the aim of no tail gas being emitted from the desulfurization regeneration tower.
