Method and device for removing steam and hydrogen sulfide generating from slurry stack

TLDR: In this article, a method and a device for removing steam and hydrogen sulfate generating in slurry are provided to prevent early corrosion of peripheral facilities by removing steam, hydrogen sulfates and air generating in a slurry and to improve working environment for workers.

Abstract: PURPOSE: A method and a device for removing steam and hydrogen sulfate generating in slurry are provided to prevent early corrosion of peripheral facilities by removing steam and hydrogen sulfate generating in slurry and to improve working environment for workers. CONSTITUTION: A steam in mixed gas of steam, hydrogen sulfate and air generating in slurry(2) is removed by cooling water(12) flowing in the opposite direction of the flow of the steam in a spray tower(4). The cooling water supplied to the spray tower is cooled by a cooling tower(6) after use. The hydrogen sulfate flows into a hydrogen sulfate removal reactor(12) by a blower and removed by aqueous solution of caustic soda by neutralization. The aqueous solution of caustic soda is preferably maintained in 9.5pH and higher.
