Innovate industrial water management models to conserve regional ecology
Surrounded by mountains and rivers, the air is fresh, the water is clear, green lotus flowers are in the sky, birds are playing, and fish are in flocks... Yanshan Petrochemical Niukouyu Wetland has transformed from an industrial wastewater pool in the past to a Beijing Internet celebrity check-in place.
"Lucid waters and lush mountains are invaluable assets." Yanshan Petrochemical has always adhered to the concept of green and low-carbon development and continued to promote industrial water management.
In 2015, Yanshan Petrochemical vigorously implemented the "Clear Water and Blue Sky" project and completed the sewage treatment standard upgrading project using international advanced treatment technologies. After the renovation, the COD (Chemical Oxygen Demand) index of Yanshan Petrochemical's external drainage was successfully reduced from 60 mg/liter to below 30 mg/liter, and the ammonia nitrogen content increased from 5 mg/liter to below 1.5 mg/liter, reaching the world's most advanced petrochemical sewage discharge control level. In recent years, Yanshan Petrochemical has adopted measures such as source management, process control and terminal purification to reduce the COD index of external drainage to below 20 mg/liter, reaching the international leading level.
In 2017, Yanshan Petrochemical adopted the internationally popular "natural treatment wetland" design concept to introduce purified water that meets the standards into artificial wetlands for advanced treatment and landscape utilization. Niukouyu Reservoir "transformed" into the first "industrial sewage treatment standards discharge + wetland natural ecological restoration system" wetland park.
In August 2018, the Niukouyu Wetland case was promoted at the World Water Week Forum in Stockholm, Sweden. Yanshan Petrochemical was invited to attend the forum and demonstrated to the world the successful experience of Chinese companies in environmental protection management and the beautiful ecology of the Niukouyu Wetland, winning unanimous praise from the participating experts.
In 2019, Yanshan Petrochemical Niukouyu Wetland built a special natural ecological conservation area with an area of 100,000 square meters and is known as the "original ecological paradise for wild birds to inhabit and reproduce."
In June 2023, the second phase of Yanshan Petrochemical Niukouyu Wetland upgrading and reconstruction project will be fully completed.

Actively create "waste-free enterprises" to achieve intrinsic environmental protection
As a pilot A-level demonstration enterprise of Sinopec's "Waste Free Group", Yanshan Petrochemical has always adhered to the bottom-line thinking, followed the principles of reduction, recycling and harmlessness of industrial "three wastes", accelerated the construction of "waste free enterprises", and continued to promote Safe, green and high-quality development of enterprises.
The management of VOCs(Volatile Organic Compounds) is a key factor in testing the environmental protection level of petrochemical enterprises, and the RTO furnace (Regenerative Thermal Incinerator) is the nemesis of VOCs. When VOCs in the industrial exhaust gas of petrochemical enterprises pass through the RTO furnace, they undergo heating degradation and purification of corresponding catalysts, and are transformed into gases that are harmless to the external environment to achieve emission standards. This is an important means for the purification and treatment of industrial exhaust gas of petrochemical enterprises.
On July 5, 2024, the RTO furnace hidden danger management project of Yanshan Petrochemical Organic Chemical Plant completed the construction and entered the joint debugging stage before commissioning. The project mainly includes the construction of a new exhaust gas heat storage device, an RTO furnace, six fans, a gas detection system and supporting transmission pipes and electrical instrument automatic control system, raw material transmission and dust removal and purification system, exhaust gas collection and pressurization transmission system and Related supporting infrastructure for collecting EVA from organic chemical plants The design scale of waste gas and tail gas generated by (ethylene-vinyl acetate copolymer), VAC (vinyl acetate) and VAE (vinyl acetate-ethylene copolymer emulsion) units is 60,000 standard cubic meters per hour. After the completion of the RTO furnace hidden danger management project, Yanshan Petrochemical Organic Chemical Plant's industrial waste gas emission standards will be more reliably guaranteed.
At Yanshan Petrochemical, the configuration of RTO furnaces covers all production units involving VOCs emissions. Not only major production units such as oil refining, ethylene, synthetic resin, synthetic rubber, and organic chemicals are equipped with RTO furnaces, but even circulating water fields and sewage purification systems have also been built to prevent a strand of exhaust gas from being discharged directly into the atmosphere without purification.
In order to strengthen the control of VOCs in the production system, Yanshan Petrochemical has built a complete VOCs grid monitoring system, established a total of 46 VOCs monitoring points, forming a VOCs monitoring network covering the production plant area and surrounding communities. Through the VOCs information management and control platform, you can grasp the VOCs emission status and change trends in the work area, factory boundary and surrounding communities in real time. The measured data are disclosed to the public and subject to government and public supervision. Since 2013, Yanshan Petrochemical has carried out LDAR (Leak Detection and Restoration Project) testing on a regular basis. A third-party organization has carried out all-weather leak testing on the production plant area to promptly discover leakage points in the production system and organize repairs to ensure Yanshan Petrochemical Industrial exhaust emissions are stable and up to standard. Under strong technical support and strict control from all over the company, from 2018 to 2023, Yanshan Petrochemical has achieved environmental protection management performance of reducing VOCs emissions by 10% for six consecutive years.
In recent years, Yanshan Petrochemical has made great efforts in hazardous waste treatment. We will make every effort to promote clean production, successfully complete the task of clean transformation of the power boiler system, achieve cleaner fuel in use in boilers, and effectively reduce the production of general industrial solid waste. Strengthen the internal comprehensive utilization of hazardous solid waste resources such as waste lubricating oil and waste catalysts, which reduces the amount of hazardous waste generated while increasing economic benefits. The implementation of the magnetic separation and comprehensive utilization project of spent catalytic cracking catalysts has reduced the generation of spent catalysts.
On December 8, 2023, the comprehensive utilization project of blue kingfisher resources dedicated to hazardous waste disposal will be fully completed. As a key environmental protection project that is widely concerned by the industry, the blue kingfisher resource comprehensive utilization device can receive and dispose of 48,000 tons of hazardous waste every year, achieving reduction, harmless and resource treatment. Its hazardous waste treatment technology has reached the domestic leading level. Smoke emission indicators are better than the requirements of national standards, landmarks and European and American standards. The completion and commissioning of the project has accelerated the construction process of Yanshan Petrochemical's "waste-free enterprise" and has a demonstration and leading role in promoting the integration of two environmental protection standards in the city and the chemical industry.
"Yanshan Petrochemical has obtained a hazardous waste business license issued by the Beijing City Ecological Environment Bureau. The blue kingfisher resource comprehensive utilization device can not only dispose of hazardous waste generated by Yanshan Petrochemical, but also dispose of hazardous waste generated by other units in Beijing City. It will help improve Beijing City's hazardous waste disposal capabilities and have positive significance for promoting the coordinated development of the economy, society and ecological environment in the capital region." said Wang Qi, manager of the Energy Management and Environmental Protection Department of Yanshan Petrochemical.
