At present, China's largest Sino-foreign joint ventures, upstream, midstream, and downstream integrated oil refining and chemical projects, the Fujian Refining and Ethylene Project, have been officially approved by the state. After more than two years of production and operation tests, the project is currently operating safely and stably. The actual output of the main products exceeds the design capacity, and the products are of good quality and have achieved good economic and social benefits. This project is currently the first domestic large-scale petrochemical production base with a tight integration of upstream and downstream industries such as oil refinery, ethylene, aromatics, and IGCC utilities. The project mainly processes Saudi Arabian crude oil and produces high-quality petroleum products. . In accordance with the driving force of the refining and chemical industry, the “synergistic†effect of the Fujian Refining Ethylene Project will drive the industrial chain of over 150 billion yuan, form a 100 billion chemical industrial cluster, and promote post-processing of petrochemicals, resins and plastics in the middle and lower reaches of the Fujian coastal economic belt. , New materials, light industry, textile and other industries have developed rapidly. The project was invested by four shareholders including Sinopec, Fujian Province, ExxonMobil, and Saudi Aramco. The total investment was 38.4 billion yuan. The drive was successful on August 26, 2009. On November 11 of the same year, the Fujian Refined Ethylene Project was officially put into commercial operation. Since the trial production of the project, a total of 178.2 billion yuan in industrial output value has been created.

Sodium tripolyphosphate (STPP) is a white, crystalline salt with the chemical formula Na5P3O10. It is commonly used as a food additive, water softener, and detergent builder. STPP is also used in industrial applications such as metal treatment, oil drilling, and ceramic production.
In food, STPP is used as a preservative, emulsifier, and texturizer. It is added to processed meats, seafood, and canned goods to improve their texture and extend their shelf life. STPP is also used in dairy products to prevent coagulation and improve texture.
In Water Treatment, STPP is used to soften hard water by binding to the calcium and magnesium ions that cause hardness. This helps to prevent scale buildup in pipes and appliances, and improves the effectiveness of soaps and detergents.
In detergent production, STPP is used as a builder, which helps to improve the cleaning power of the detergent by binding to hard water ions and preventing them from interfering with the cleaning process.
Despite its widespread use, STPP has been the subject of some controversy due to its potential environmental impacts. When released into waterways, STPP can contribute to eutrophication, which is the excessive growth of algae and other aquatic plants that can harm aquatic ecosystems. Some countries have placed restrictions on the use of STPP in certain applications to minimize its environmental impact.
