In the first half of this year, the company shut down the calcium carbide production line that has been operating for more than 30 years. In the second half of the year, most of the technological equipments of the acetylene section, the synthesis section and the rectification section of the organic plant were shut down. So far, the company's leading product PVA production front-end process from the production of acetylene by the acetylene-acetylene process to the direct purchase of ethylene production of vinyl acetate, marking the basic elimination of the "three high" process, the company is accelerating the development of environmentally friendly companies change. The company’s employees truly felt the significant improvement in the company’s production environment.
The company's leading product for the production of polyvinyl alcohol has always been a calcium carbide-acetylene feedstock process route. Production of polyvinyl alcohol by the calcium carbide-acetylene method. In the case of only one furnace (with two furnaces), the calcium carbide plant uses more than 2,100 tons of coal per month, and uses more than 3,700 tons of lime per month. Electricity 11.5 million kWh/month, and more calcium carbide slag and calcium carbide slag liquid will be produced during the production process. Due to the strong alkalinity of the calcium carbide waste, there is some carelessness. Slag heap collapse may occur, causing serious environmental safety accidents. Although most of calcium carbide slag liquids have been reused in circulation plants, overflows may occur due to abnormal weather, causing contamination of surrounding farmland and causing disputes. In order to install calcium carbide waste residue "home", the company has invested heavily in nearly two acres of land acquisition, as a calcium carbide waste residue field. In order to prevent environmental pollution and ensure the safety of dams, the company has to invest a lot of manpower, material resources and financial resources each year.
After shutting down some of the process lines for calcium carbide, organic synthesis and distillation, the high-risk raw materials such as coke, lime, calcium carbide, organic chlorine, and coal touch in the calcium carbide plant have all been suspended. Starting from August this year, the company’s electricity consumption has been suspended. The amount of electricity saved was over 13 million kWh/month, which was a drop of more than 75%. The amount of physical coal used for combined heat and power production dropped from 1,300 tons per day to more than 500 tons per day. The company continued to improve the quality of raw coal entering the plant, using good coal and using less coal, and drastically reduced emissions of cinder, boiler fumes, industrial dust, and sulfur dioxide. The three calcium carbide waste dumps that the company hailed as “three mountains†were all cleared before the end of October this year. The hidden dangers of calcium carbide slag and calcium carbide slag liquids have been completely eliminated, and more than 100 acres of available land have been replaced. , to make room for the company's continued development.
In April this year, the company also reformed some of the circulating water systems, making the main production water recycling rate more than 85%. The company's sewage treatment station adopts a highly efficient and practical SBR process with a daily processing capacity of 9,600 tons and a monthly basic operating cost of more than 200,000 yuan. Even if the financial crisis is extremely difficult, the company will maintain the normal operation of the sewage treatment station and ensure that the discharge of production wastewater reaches the national first-class discharge standard.
Since the financial crisis, the company's downstream textile origin and building materials market have been greatly affected. The sales price of the company's leading product, polyvinyl alcohol, dropped from nearly 20,000 yuan per ton to just over 10,000 yuan per ton, a drop of nearly 40%. , and the cost of manufacturing is seriously reversed. On the one hand, the company leads its staff to do everything possible to deal with the financial crisis, ensure that the company does not stop production, the capital is continuously linked, and the employees have positions; on the other hand, through the study and practice of the scientific concept of development, the company constantly optimizes the production model, adjusts the sales strategy, and vigorously develops the tight integration with production. Special activities aiming at reducing consumption and increasing efficiency. Since the beginning of this year, the company’s leading product PVA production costs have fallen month by month. The cost per ton has dropped from the highest value of RMB15,700 to RMB10,400, which has effectively reduced the price per ton of sales after the financial crisis by more than RMB5,000. In the predicament, the comprehensive energy consumption per 10,000 yuan output also fell from 5.6 tons of standard coal in January to 2.01 tons of standard coal in mid-October.
Although the company was awarded the title of “Advanced Unit for Major Pollutant Emission Reduction in Jiangxi Province†and “Advanced Unit for Water Conservation in Jiangxi Provinceâ€, the energy saving and emission reduction work was repeatedly affirmed by the inspection team of the Provincial People's Congress Environment Protection Committee, but the company’s leadership It is recognized that if enterprises are to become truly environmentally-friendly, they must further scientifically adjust their production processes, increase their investment, and achieve both good results and environmental protection.
Jiangxi Chemical Fiber has achieved remarkable results in energy saving and emission reduction
Jiangxi Chemical Fiber Chemicals Co., Ltd. is a large-scale chemical fiber combined production enterprise. Over the years, the “three highs†(high energy consumption, high pollution, and high risk) have restricted the company’s development. Since the study and practice of the scientific concept of development started, the company has focused on energy conservation and emission reduction. It has actively and boldly optimized the production model, improved the process route, and achieved remarkable results.
