On October 13, the National petroleum and chemical industry carbon peak, carbon neutral development Forum and energy efficiency "Pacesetter", water efficiency "pacesetter" press conference was held in Beijing, at which the "13th Five-Year" energy-saving advanced units and individuals were commended。Henan Energy Yongcheng Park, with Henan Longyu Coal Chemical Co., LTD as the main body, has been selected as the national "13th Five-Year Plan" energy-saving advanced unit list, becoming the "leader" of low-carbon development of chemical industry.。

　　Yongcheng Industrial Park is one of the four major chemical industrial parks of Henan Energy and Chemical Group. It is located in Yongcheng Industrial agglomeration Zone of Henan Province。The park includes Henan Longyu Coal Chemical Co., LTD., Yongcheng Yongjin Co., Ltd. and related supporting facilities, with an annual output of 500,000 tons of methanol, 200,000 tons of dimethyl ether, 400,000 tons of acetic acid and two sets of 200,000 tons of ethylene glycol plants。The 13th Five-Year Plan period，The park adheres to the principle of "development and economy，Giving priority to conservation and emission reduction in energy development，Build three systems for energy use，Take a combination of measures to conserve energy and reduce emissions，Strive to be a "pacesetter" in low-carbon development，Strive to create resource-saving and environment-friendly enterprises，It has made positive contributions to social and economic development and the building of a beautiful China。

　　Build three systems for energy use

　　"In 2020, the comprehensive energy consumption of methanol per unit product is 1364 kg standard coal tons, which is better than the national standard advanced value of 14.8%；乙二醇单位综合能耗为991千克标准煤吨，优于国标先进值5.2%；全年节能12000多吨标准煤。Hou Liutao, chief engineer of the park, said。

　　Behind a series of figures, is the hard work and sweat of Longyu coal chemical workers......

　　Establish and improve the pre-evaluation system of energy utilization。Yongcheng Park took the initiative to check the standards and tables. In June 2019, it passed the certification of quality, environment, occupational health and safety and energy management system, and won the "green pass" in the international market, which prevented energy waste at the source and improved the utilization rate of resources。

　　We will establish and improve a control system for energy use。For the coal chemical industry as the main industry of Yongcheng Park, coal, electricity, steam is the key energy consumption of the working medium。The park has not only formulated Production and Service Control Procedures, Production Process Operation and Key Energy Use Equipment Control Procedures and other relevant procedural documents for constraints based on the actual situation, but also established an energy utilization post responsibility system to ensure the implementation of all work。

　　Establish and improve the energy utilization measurement system。The park has set up an energy control center，Equipped with accurate measuring equipment，We will improve the energy metering ledger and the management ledger of major energy-consuming equipment，And successfully used enterprise OPC data automatic acquisition system, PIMS data integrated control system and intelligent power management and control system，Statistical production process parameters and energy consumption data every day，To provide reliable technical support for the full utilization of energy。

　　Take a combination of measures to conserve energy and reduce emissions

　　Yongcheng Park actively explores new paths of energy conservation and emission reduction, plays a good combination of cost reduction and efficiency, and constantly tightening the "master valve" of leakage.。

　　In terms of production process, the new mode of "interconnection and optimization of operation" is carried out scientifically to realize the interconnection of raw gas, by-product steam and public works among the first and second phase plants, which releases the potential of the plant with minimum comprehensive energy consumption and improves the utilization rate of raw materials。In addition, through specific measures such as coal quality management and process optimization, the park has achieved a long-term boiler operation breakthrough of 373 days, creating an advanced level of domestic counterparts。

　　In terms of water resources utilization, the park adheres to the road of circular economy, low-carbon economy and green economy development. It has invested in the construction of regional sewage treatment plant, which deeply treats and recyles more than 10 million tons of local municipal sewage and waste water from five major coal mines every year。At the same time, it also integrates low-grade heat sources in the park to efficiently recycle heat energy for central heating in Yongcheng City, benefiting local people and demonstrating the responsibility of state-owned enterprises。

　　In terms of electricity conservation, the park has comprehensively optimized the power system, replacing high-power motors with water turbines and steam turbines, replacing traditional motors with variable frequency motors, and supplementing power consumption with solar energy。According to statistics, during the 13th Five-Year Plan period, the total amount of electricity saved annually exceeded 40 million KWH。

　　The park also uses the fly ash and slag generated in the production process to manufacture cement and gangue bricks respectively, and uses the acid gas generated to produce industrial sulfur, insisting on "eating dry and pressing clean".。

　　"Energy conservation and emission reduction work involves everything from scientific and balanced production models to saving one drop of water and one kilowatt of electricity。Only by extensive mobilization, full participation, reasonable allocation and penny-pinching can we obtain the maximum economic and environmental benefits with minimal consumption。"The park general manager Xie Feidong said deeply feeling。

　　Strive to be a "pacesetter" in low-carbon development

　　Yongcheng Park attaches great importance to the work of "production, learning and research", constantly increasing cooperation with universities and research institutes, exploring the application of new technology and new equipment, and planning new topics of transformation and development。

　　Yongcheng Park anchors the "1+4" development strategy of Henan energy, makes precise efforts in biodegradable plastics, high-performance organic solvents, raw materials for new energy batteries and other fields, promotes the transformation and upgrading of the industry to high-end and fine, and has been confirmed as the "two-carbon" target pilot unit by Henan Province。

　　The park set up "Ten Key technology research teams"，The 13th Five-Year Plan period，The use of carbon dioxide recovery gas instead of nitrogen gas as gasifier coal transport gas project，每年减排二氧化碳超过12万吨；对醋酸装置废锅流程进行改造，每年节约标准煤超过1万吨；加大锅炉尾气掺烧力度，每年可节约标准煤8000吨……实实在在的成效，Substantial income，Inject new vitality into the continuous development and expansion of Yongcheng Park。

　　"Now, the park is planning supporting projects for industrial transformation, such as improving the efficiency of comprehensive utilization of water resources, photovoltaic power generation and comprehensive utilization of carbon dioxide, to lay a solid foundation for high-quality development of enterprises。"The park district Party secretary, chairman Liu Pintao firmly said。
