Tail Gas Treatment Skid

(1) 600×104 m3/d tail gas treatment plant for CNPC

performance001

The project is a tail gas treatment unit with a design capacity of 600 ×104 m3/d in CNPC Gaomo purification plant. It is mainly used to treat Claus tail gas of sulfur recovery unit, as well as liquid sulfur pool waste gas of sulfur recovery unit and TEG waste gas of dehydration unit. The design treatment capacity of the unit is matched with sulfur recovery unit and dehydration unit. The plant adopts CANSOLV process approved by Shell company and the tail gas after treatment can reach the SO2 emission standard of 400mg/Nm3 (dry basis, 3vol% SO2).
