  On October 13, the national Petroleum and chemical industry carbon peak, carbon neutral development forum and energy efficiency "leader", water efficiency "leader" conference was held in Beijing, commended the "13th Five-Year" energy-saving advanced units and individuals。Henan Yongcheng Energy Park, with Henan Longyu Coal Chemical Co., LTD as the main body, has been selected into the list of advanced energy-saving units in the 13th Five-Year Plan and become the "leader" in the low-carbon development of the chemical industry.。

  Yongcheng Industrial Park is one of the four major chemical industrial parks of Henan Energy and Chemical Group, which 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 2 sets of 200,000 tons of ethylene glycol。During the 13th Five-Year Plan period,The park insists on paying equal attention to development and economy,Conservation and emission reduction priority "energy development policy,Building a three-tiered system for energy Utilization,A combination of measures to save energy and reduce emissions,To be the "leader" 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。

  Building a three-tiered system for energy Utilization

  "In 2020, the comprehensive energy consumption of methanol per unit product will be 1364 kg standard coal ton, better than the advanced national standard 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。"Said Hou Liutao, chief engineer of the park。

  Behind a series of figures, longyu coal chemical workers pay the hardships and sweat......

  Establish and improve the pre-evaluation system for energy utilization。Yongcheng Park takes 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 obtained the "green pass" of the international market, eliminating energy waste and improving resource utilization rate from the source。

  Establish and improve the energy use control system。For yongcheng industrial park with coal chemical industry as the main industry, coal, electricity and steam are the key energy consumption working medium。The park not only formulated production and Service Control Procedures, Production Process Operation and Key Energy using Equipment Control procedures and other relevant procedural documents to constrain the park, but also established the energy use post responsibility system to ensure the implementation of various works。

  Establish and improve energy utilization measurement system。An energy source control center is set up in the park,Equipped with precise metering equipment,Improve the energy metering ledger and the management ledger of major energy-consuming equipment,The OPC data acquisition system, PIMS data integration control system and intelligent power control system have been successfully applied,Daily statistical production process parameters and energy consumption data,Provide reliable technical support for full utilization of energy。

  A combination of measures to save energy and reduce emissions

  Yongcheng Park actively explores new paths of energy conservation and emission reduction, makes overall plans to cut costs and increase efficiency, and keeps tightening the "master valve" of running and leaking.。

  In terms of production process, the new mode of "interconnection and optimization operation" has been carried out scientifically to realize the interconnection of raw gas, by-product steam and public works between the first and second phase units, so as to release the potential of the device with the minimum comprehensive energy consumption and improve the utilization rate of raw materials。In addition, the park also through coal quality management, optimization of the process and other specific measures, to achieve a long period of boiler operation beyond 373 days, creating the domestic peer advanced level。

  In terms of water resources utilization, the park adheres to the development path of circular economy, low-carbon economy and green economy, and invests in the construction of regional sewage treatment plant, which deeply treats and recycles 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 and efficiently recovers heat energy for central heating in Yongcheng, benefiting local people and demonstrating the responsibility of state-owned enterprises。

  In terms of power saving, the park has optimized the power consumption system comprehensively, 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, more than 40 million kilowatt hours of electricity will be saved every year。

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

  "Energy conservation and emission reduction work involves all aspects, from the scientific and balanced production mode to the small saving of a drop of water or one kilowatt of electricity。Only by widely launching, full participation, rational allocation and penny-fighting can we obtain the largest economic and environmental benefits with the minimum consumption。"The park general manager Xie Feidong said deeply touched。

  To be the "leader" in low-carbon development

  Yongcheng Park attaches great importance to the work of "production, learning and research", and continuously increases cooperation with universities and scientific research institutes to discuss the application of new technologies and new equipment and plan new topics for transformation and development。

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

  The park set up "Ten major technical teams",During the 13th Five-Year Plan period,Using carbon dioxide recovery gas instead of nitrogen as gasifier carrier 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,Considerable gain,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 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。
