Jiujiang Petrochemical Co., Ltd. is actively advancing clean production by aligning with the principles of a circular economy. The company has established a comprehensive system for the utilization of "three wastes" (waste gas, waste water, and solid waste), transforming them into valuable resources. This approach not only promotes resource recycling and industrial synergy but also delivers significant economic and environmental benefits.
Leveraging technological innovation, the plant has successfully turned waste into valuable products. For instance, all acid gas is now directed to the sulfur recovery unit, where nearly 8,000 tons of sulfur are produced annually, boosting profits by over 1 million yuan. Additionally, a new wet oxidation device for soda slag and a brick factory with an annual capacity of 22 million blocks have been constructed. These initiatives recover about 500 tons of naphthenic acid from soda residue and utilize over 200,000 tons of fly ash, generating nearly 1 million yuan in output value while reducing pollution and improving efficiency.
This year alone, the company used nearly 100,000 tons of combustible gas to treat 4 million tons of oil refining wastewater, handled 17,000 tons of alkaline slag, recovered 5,400 tons of sulfur oil, 6,300 tons of sulfur, and 417 tons of naphthenic acid, achieving a total comprehensive utilization output value of 20 million yuan. Furthermore, the plant has benefited from tax reduction and exemption policies for resource utilization, successfully applying for the “three wastes†utilization program in Jiangxi Province, which received strong support from local authorities.
The dry gas generated from the refinery is now used as fuel for heating furnaces and power boilers in the refining process. It also contains various petrochemical raw materials, allowing the company to make better use of low-value resources. By adjusting the route of fertilizer raw materials and using synthetic gas from the refinery, the plant saves 3 tons of residual oil per hour, leading to an annual efficiency gain of over 20 million yuan. Through these efforts, Jiujiang Petrochemical continues to demonstrate its commitment to sustainable development and efficient resource management.
