China Drying News reported that “raising the technological level and industrial concentration is the key point for the oil and chemical industry to further improve the circular economy system.†This is an interview with the reporter on the “Twelfth Five-Year†Circular Economy Development Plan just released by the country. Information learned by industry experts. The plan requires that by 2015 the resource output rate should be increased by 15%, and the chemical industry must establish a sound circular economy system. Industry experts said that at present, China's petrochemical industry has achieved certain results in the recycling economy, but there is still a lot of room for development. Li Yongliang, deputy director of the Industrial Development Department of the China Petroleum and Chemical Industry Federation, told reporters that as a resource-intensive oil and chemical industry, significant progress has been made in the development of recycling economy in the past few years, and industries such as sulfuric acid, chlor-alkali, calcium carbide and coking have Established a relatively complete circular economy industrial chain. Xinjiang Tianye Group's chlor-alkali, calcium carbide recycling economy industry, Lubei Chemicals, Kaifeng Group's phosphorus chemical industry chain, as well as Shanghai Chemical Industry Park and other petrochemical parks, are typical representatives of the industry's circular economy. The Deputy Secretary-General of the China Coking Industry Association, Yang Wenyu, told reporters that the unique processing methods of the coking industry have enabled coal, which was originally fuel, to achieve the greatest degree of resource utilization. About 75% of products produced from coal carbonization are coke, about 18% are coal gas, and about 5% are tar and benzene. The coke is used for blast furnace ironmaking or other industrial purposes; the technology for producing methanol from coke oven gas has matured, and the world's first coke oven gas LNG has also been put into production at the end of last year; coal tar deep processing can yield quinoline, carbazole, methyl Dozens of scarce chemical products such as naphthalene meet the needs of industries such as medicine, dyes, and preparations. “In addition, the promotion of CDQ technology and the recovery of flue gas heat have made some companies become centers of heat or electricity supply,†said Yang Wenxuan. The president of China Sulfuric Acid Industry Association, Qi Wei, told reporters that in the sulfuric acid production process, the biggest recycling highlight is energy recycling. At present, more than 80% of large and medium-sized enterprises can recover more than 90% of the heat generated during the sulphuric acid production process. Pyrite 60% of the thermal energy in the acid is recycled. Qi Qi said that there is no solid waste generated during the production of sulfuric acid, and high concentrations of exhaust gas can be recovered through tail gas recovery and acid production. The amount of waste water generated is also small, and wastewater can be used to make ammonium sulfate, recycle water, slag humidification, beneficiation . Experts in the industry have stated that although the recycling economy in some areas of the industry is already in a leading position in the world, there are still many areas for improvement to meet the requirements of the national circular economy development plan. Experts believe that breakthroughs in related technologies and equipment are the key. “The further deep processing and high-efficiency separation technology of coal tar products is still relatively lacking, and the technology of coke oven gas to ethylene glycol and others has yet to be broken through,†said Yang Wenxuan. Qi Hao also said that in order to further increase heat recovery, the Sulfuric Acid Association is working to accelerate the maturation of technologies such as low-temperature heat recovery. The large-scale comprehensive utilization of phosphogypsum looks forward to the improvement of technology. Li Yongliang pointed out: "Equal to the technological breakthrough is equally important to further increase industrial concentration." He believes that the petrochemical industry can only be concentrated, achieve a major cycle, and the industrial chain can be opened in order to finally form a scientific, efficient, and perfect circular economy industrial chain. .
