Industrial Application of Rotary Jet Technology in Environmental Protection Treatment of Tank Top Gas in Delayed Coking Units
This article introduces the industrial application of rotary jet technology in the environmental protection treatment of gas at the top of cold coke water tank and cut coke water tank in a delayed coking unit of a petrochemical enterprise.After the application of this technology,hydrogen sulfide was removed from the top gas of the cold coke water tank and the cut coke water tank,solving the problem of foul odor in the top gas of the tank and the problem of hydrogen sulfide corrosion in subsequent VOCs treatment facilities;The removal of coke powder from the top gas of the cold coke water tank and the cut coke water tank has alleviated the problem of easy blockage of subsequent VOCs treatment facilities,ensuring the continuous and stable operation of the entire system.After the top gas of the cold coke water tank and the cut coke water tank is washed and desulfurized by rotary spray,the coke powder removal rate is ≥99％,the total sulfur content in the purification tank top is not more than 10 mg/m3,and the liquid droplet content is not more than 50 mg/m3.
