During the “Eleventh Five-Year Plan†period, the national “Eleventh Five-Year Plan†regards the development of circular economy as a major strategic task, and the 17th CPC National Congress clearly puts forward that the circular economy should form a large scale. On January 1, 2009, the "Circular Economy Promotion Law" was formally implemented to make the development of circular economy into the legal system. The country strongly promotes the development of circular economy and provides an opportunity for the petrochemical industry.
During this period, the petroleum and chemical industries vigorously developed a recycling economy, focusing on the principle of “reduction, reuse, and recycling†and improving the utilization of resources, focusing on resource conservation, comprehensive utilization of resources, and cleaner production. We will adjust the structure, technological progress, and strengthen management measures to significantly reduce resource consumption, reduce waste emissions, and increase labor productivity. In the past five years, the circular economy has gone deep into the oil and chemical industry and has made considerable progress.
The petrochemical industry is a top priority in the circular economy pilot enterprises and parks that have been launched in the country and around the world. For example, Guizhou Hongfu Industrial Co., Ltd. has vigorously carried out technological innovation, actively explored and practiced circular economy, and became an advanced model for the development of circular economy. It has become China's largest phosphate fertilizer production base within a few years. Xinjiang Tianye (Group) Co., Ltd. is in the industry. The layout focuses on the cyclical combination of major industries and the efficient recycling of resources within the industry. Through years of practice, Shandong Lubei Enterprise Group Co., Ltd. has formed ammonium phosphate, sulfuric acid and cement co-production, seawater “one-purpose water use,†and clean power generation. Salt, alkali co-production 3 circular economy industrial chain......
In the past five years, the circular economy of the petrochemical industry has become a common practice and has achieved remarkable results. Many companies in the industry have significantly improved the overall utilization rate of resources through technological innovation, realized the recycling of “three wastes†and turned waste into treasure. The chemical industry park has realized industrial interconnection and coupling through rational industrial layout, and realized the mutual utilization of resources among enterprises. Share development. Li Yongwu, president of the China Petrochemical Federation, recently summarized the achievements of the “Eleventh Five-Year Planâ€, saying that the entire industry is vigorously developing circular economy, and the major pollutants binding indicators have basically been completed, and the goal of reducing energy consumption per unit GDP by 20% can also be basically achieved.
Circular economy is divided into three levels. For the "small loop", the "phosphorus opening phenomenon" is a representative. Guizhou Kaisuo Group actively developed circular economy and built the first domestic production line with independent intellectual property rights and an annual output of 100 million pieces of high-strength water-resistant gypsum standard bricks; a tailings slag brick-making factory was built to obtain waste thorium in underground mining. Make full use of it to reduce the occupation of land by waste residue and reduce environmental pollution. Shaanxi Beiyuan Chemical Industry Group is transforming itself into a recycling economy. With an annual output of 1 million tons of PVC, the project can reduce emissions by 3.6 million tons of carbon dioxide per year and achieve zero emission of “three wastesâ€. Such companies are numerous in the industry.
In the "cycle" and "big cycle" aspects, during the "11th Five-Year Plan" period, the development of the chemical industry park with the concept of resource recycling, enterprise recycling, and industrial recycling is in full swing. In Shanghai, Shanghai Chemical Industry Park has embarked on a world-class circular economy tour. At present, the recycling rate of industrial water in Shanghai Chemical Industry Park is 97%, and the comprehensive utilization rate of industrial solid waste is 89.19%, which is higher than the average level of 80% in the world. The annual emission of sulfur dioxide and chemical oxygen demand is much lower than that in Shanghai. Control level. In addition, Shaanxi Shaanxi North Energy and Chemical Industry Base, Ningbo Chemical Industry Zone, Nanjing Chemical Industry Park, Gansu Hexibao Chemical Circular Economy Industrial Park, Jiangxi Xinghuo Industrial Park, Chongqing Chemical Industry Park, Xinjiang Zhongtai Chemical Fukang Industrial Park, Inner Mongolia Tuoketuo Industrial parks and Mengxi High-tech Industrial Park, etc., the development of circular economy is also swift and violent.
To develop a recycling economy, technological innovation is the key. During the “Eleventh Five-Year Plan†period, the petrochemical industry developed and promoted a large number of new technologies and new processes to save resources and reduce pollution, which provided strong support for the development of circular economy. Among them, there are two major categories of technological achievements are particularly prominent: First, low-quality raw materials and comprehensive utilization of waste technologies, such as residue olefins cracking technology, continuous gasification of pulverized coal to syngas technology, phosphogypsum sulfuric acid cogeneration cement technology , carbonyl synthesis to acetic acid technology; Second, in the production process can significantly reduce emissions, save resources and energy technologies, such as non-calcium roasting red wolfberry sodium production technology, ion-exchange membrane caustic soda technology, wet-process phosphoric acid and purification of pyrogenation phosphoric acid technology. In addition, the rubber industry reclaimed rubber and rubber powder development and utilization, chlor-alkali industry calcium carbide slag cement, calcium carbide slag flue gas desulfurization and Other technologies, but also outstanding scientific and technological achievements of the circular economy.
During the "11th Five-Year Plan" period, the circular economy played an important role in the petrochemical industry, and laid a solid foundation for the "12th Five-Year Plan" industry to adjust the structure, transfer methods, and fully enter the new industrialization track.
During the "Eleventh Five-Year Plan" period, while China's oil and chemical industry continued to grow at a high rate, the traditional mode of extensive development is also brewing a fundamental change. In the past five years, circular economy has taken the forefront for the first time. The resource production rule of “resources-products-waste-recycling resources†has given power to the oil and chemical industry to adjust the structure and transfer methods, achieve sustainable and healthy development, and gradually develop the industry-wide circular economy system. Into good situation. In the past, the dilemma of resource and environment and economic development gradually became “butterfly changeâ€, and “dilemma†was turning into “win-winâ€.
