Jinneng Holding Equipment Manufacturing Group's Coal Chemical Sector: Technology Leads and Tripartite Efforts to Take the Road of Green and Low-carbon Development
Under the background of "dual carbon", the national control policy has changed from "dual control" of energy consumption to "dual control" of total carbon emission and intensity, which has a huge impact on the coal chemical industry. To this end, the coal chemical sector of Jinneng Holding Equipment Manufacturing Group closely follows the policy requirements, based on the actual situation of the enterprise, and carries out solid basic research in terms of source carbon reduction, process carbon reduction and terminal carbon sequestration, and takes the road of green and low-carbon development with practical actions.
In terms of total carbon emission control, we will focus on coal saving, do a good job in reducing carbon emissions at the source, and mainly study the structural adjustment of raw coal.Compared with the previous full-burn high-sulfur anthracite coal, the coal consumption per ton of alcohol raw material decreased by 48 kg of standard coal, the amount of flux decreased by 38.6%, and the active gas composition increased by 1.7%. The JM-S furnace can reduce the consumption of ammonia raw material coal by 18 kg per ton of standard coal, and the by-product of the waste heat recovery system is 13.5t/h of medium-pressure steam. At the same time, the trial burning of briquette in the Lurgi furnace and the blending of anthracite coal in the aerospace furnace with Shenmu coal as raw material are also being carried out in an orderly manner. In addition, the introduction of new energy sources, such as Sanning's photovoltaic power generation project, can also reduce coal power use and carbon emissions; Combined with the advantages of gas resources of the group company, Jinxiang Company is studying the coupling development of coal chemical industry and coalbed methane, which will reduce carbon emissions by reducing methane emissions, which will also produce obvious carbon emission reduction effects.
In terms of carbon emission intensity control, energy conservation is the mainstay, carbon reduction in the process is carried out, and systematic energy cascade utilization and optimization are mainly carried out.By combing the energy utilization of each section, the problems are found to be improved and improved, so as to achieve better and more full use of the system energy. Among them, Huayu's 22MW condensation unit did not increase the investment in technical transformation, but only increased the power generation capacity by 1200kWh per hour through optimized operation; Tianqing Company improved the mismatch between the design and reality of some pipelines in the steam pipeline network, saving about 1.13 million yuan per year. In particular, the system optimization plan of Huayu and Tianqing companies has passed the review, and 17 technical transformation projects have been included in the company's plan for next year, which will continue to optimize energy utilization.
In addition, research on terminal carbon sequestration products is carried out.For example, the liquid carbon dioxide project of Shandong Alliance Company sells carbon dioxide as a product; Huayu Company carried out research on nano calcium carbonate technology, and used idle MTG devices to convert xylene production to reduce carbon emissions.
In the next step, the coal chemical sector of Jinneng Holding Equipment Manufacturing Group will focus on the direction of "three modernizations", based on the actual situation of the enterprise, borrow wisdom from scientific research institutions, continue to deepen the scientific research projects that have been carried out, and at the same time conduct follow-up research on cutting-edge technologies such as green ammonia and green alcohol that are in line with the prospects of industrial development, promote the transformation of coal into raw materials, materials and end products, and realize the green and low-carbon development of coal chemical industry.
