Standby dry quenching project for the 1.8 million tons/year coking project of Jiexiu Changsheng Gasification Co., Ltd

Thread Content

Project Name: Backup Dry Quenching Project for the 1.8 million tons/year coking project of Jiexiu Changsheng Gasification Co., Ltd.
Owner: Jiexiu Changsheng Gasification Co., Ltd.
Project Nature: Technical upgrade (no increase in coking capacity)
Total Investment: 120 million yuan
Filing Date: March 20, 2026
Construction Period: Planned from March 2026 to April 2027
Construction Location: Jiexiu Economic and Technological Development Zone, Jiexiu Chemical Circular Economy Industrial Park (Changsheng Company’s Second Plant, Zhanglan Village, Zhanglan Town)

Construction Scale and Scope:
New construction of a 230t/h dry quenching unit along with associated boilers.
Supporting facilities: J201/J202 coke conveyor corridors, air coolers, dust removal systems at transfer stations, and dust removal systems for high-sulfur content in the dry quenching process.
Upgrades: Raising the height of J101/J102 conveyors, boiler feed water pump stations, and adding floors to the electrical rooms for the dry quenching unit; upgrading the circulating water system.
Reuse of existing facilities: Steam turbine power generation station, comprehensive electrical room for the dry quenching unit, and ground-based dust removal systems.

Project Background and Significance:
Leveraging the company’s main 2×65-chamber, 6.78-meter-high coke ovens with an annual production capacity of 1.8 million tons, this project pairs them with the existing 230t/h dry quenching unit, providing one unit in active use and another as a backup. This arrangement enhances the continuity and stability of production； Enhancing waste heat recovery, reducing costs and improving efficiency, as well as minimizing pollution, is in line with the trend of green technological upgrades in the coking industry.
