Abstract

At oil refining and petrochemical industry enterprises, one of the main environmental problems is as-sociated with the need to neutralize or dispose of waste alkaline solutions and aqueous process con-densates contaminated with sulfur compounds, which make up sulfur-alkaline wastewater. This paper addresses the issue of reducing alkali consumption and reducing sulfur-alkali wastewater by optimiz-ing the stages of hydrogen sulfide stripping and alkalization during the hydrotreating of catalytic cracking gasoline
