Advancing Environmental Protection Technologies in the Petroleum and Chemical Industry

The Petroleum and Chemical Industry Exchange was successfully concluded on June 23. It focuses on new technologies, products and equipment for environmental protection in the petrochemical industry.

According to the China Petroleum and Chemical Industry Association, at present, many fields in the petroleum and chemical industry still lack effective and applicable advanced technologies for energy saving and emission reduction. In particular, high concentration of organic wastewater containing salt, organic waste gas and hazardous waste treatment technology. Technology backwardness is a major bottleneck in the development of environmental protection. With no breakthrough in advanced and applicable technology, it is impossible to have a major breakthrough in energy conservation and industry development.

At the same time, the petroleum and chemical industries have become the focus of national pollution control. In the State Environmental Protection Administration to determine the national key monitoring enterprises, there are 3,592 sources of waste gas pollution and 3,115 sources of wastewater pollution. Among them, there are 482 waste gas pollution sources and 803 wastewater pollution sources in the petroleum and chemical industry.

Due to the lack of economically rational and reliable environmental technology, some enterprises want to cure pollution, but there is no way to achieve it. For example, in the production of pesticide insecticides, fungicides, herbicides, and other original drug species, the chemical oxygen demand in the discharge of wastewater up to several thousand to tens of thousands of milligrams per liter. Dyestuff and pigment wastewater has a wide variety of pollutants and complex components. The water quality and water quantity vary widely, the concentration is high, the biochemical property is poor, and the treatment is very difficult. Enterprises reflect that they hope there will be more environmental protection technology and products that can solve the actual problem emerge.

According to the China Petroleum and Chemical Industry Association, in order to break through the bottleneck of environmental technology as soon as possible, China's petroleum and chemical industry will increase the research efforts on resource conservation and recycling of key technologies. Priority development of oil refining, ammonia, sulfuric acid, caustic soda, calcium carbide, pesticides, dyes, paints, inorganic salts and other production volumes, the number of enterprises, wide distribution and serious pollution of bulk chemical products clean production technology and waste recycling technology. Organic raw materials, pesticides, dyes, some fine chemicals and other industries emitting organic pollutants containing aromatic hydrocarbons, halogenated alkanes, organic sulfur and phosphorus compounds and other difficult to degrade wastewater reduction technology. Ammonia nitrogen wastewater source reduction technology. Dye and titanium dioxide production dilute waste sulfuric acid thickening technology. Comprehensive utilization technology of chrome slag, phosphogypsum slag, calcium carbide slag, etc.
