"Carbon peak" and "carbon neutrality" are the current hot words, according to the set goals, China strives to achieve carbon peak by 2030 and carbon neutrality by 2060. In March this year, the Ministry of Human Resources and Social Security and other three departments released a new social occupation, "carbon emission administrators" are among them, and how well the current and future "carbon peaks" and "carbon neutrality" are done depends on these administrators. This new profession sounds very "green", so, what is a "carbon administrator"? What do you do in your daily work?
Hao Jinming is the newly appointed "carbon emissions administrator" of Tianjin Bohua Yongli Chemical Co., Ltd., previously her position was called energy conservation commissioner, "after becoming a carbon emission administrator, the content of management is more, to do a good job of carbon emission accounting for enterprises, so that carbon emissions have tangible benefits." Hao Jinming said that now that the carbon trading market is open, the better the energy conservation and emission reduction, the higher the profit, and the more obvious the social and economic benefits.
As the person in charge of energy conservation management of Bohua Wynn and the director of the Quality Management Center, Zhao Qiang is not low in requirements for himself and his colleagues, "Carbon emission administrators must not only understand policies and standards, but also understand various related technologies, and even coordinate the relationship between production and environmental protection, which is reflected in the daily work of testing, statistical accounting, verification, trading and consulting on the carbon emissions of greenhouse gases such as carbon dioxide." ”
Recently, Bohua Wynn is in the period of shutdown and maintenance, Hao Jinming said, "Using this shutdown machine, we will replace the methanol synthesis and octanol hydrogenation catalyst, implement the micro-interface technology transformation of the butanol device, waste heat refrigeration, optimized operation of the base, and application of motor energy-saving technology... A series of optimization projects have been transformed to achieve the purpose of burning less coal and improving combustion efficiency. At the same time, improving the quality of raw coal is also one of the means for Zhao Qiang and Hao Jinming to let enterprises achieve "double carbon", "1kg of raw coal is burned to produce heat of about 5650 kcal, when the raw coal per kilogram increases by 100 kcal, we can use about 2000 tons of coal per month." ”
Tianjin Bohua Yongli Chemical Co., Ltd. is a collection of marine chemical, coal chemical, petrochemical as one of the chemical enterprises, coal combustion process is a chemical reaction process, in the generation of nearly 4 times the weight of carbon dioxide at the same time, release the combustion heat. "In fact, the carbon dioxide emitted is just as valuable as the heat released by the combustion process." Hao Jinming said, "Recycling and energy saving and emission reduction are crucial for double carbon work. Hao Jinming pointed to the recently successful operation of the 100,000 tons / year carbon dioxide exhaust gas recovery and comprehensive utilization project.
Previously, the company also built a recycling device that recovers 50,000 tons of carbon dioxide exhaust gas per year, and the recovered carbon dioxide can reach the food grade, "These purified carbon dioxide can be added to carbonated beverages as a liquid, turned into a solid to make dry ice, and can also inject carbon dioxide into underground rock formations for geological storage." Zhao Qiang said that people have long grasped the "sesame" of burning heat and thrown away the "watermelon" of burning chemical products, and now the enterprise can save 0.75 million tons of standard coal every year while achieving an annual output value of 65 million yuan.
At present, under the impetus of the carbon emission administrator, the factory is building a distributed photovoltaic power station project for waterproof building photovoltaic integration, photovoltaic power generation has achieved a green alternative to traditional energy, Liu Yuna, minister of the Planning and Development Department, said, "We are mainly responsible for the construction of the project, simply put, the suggestions and opinions put forward by the carbon emission administrator After the company agrees, we will promote the follow-up work. In the future, the annual photovoltaic power generation capacity can reach 7.1767 million kwh, and the power can reach 7 MW, which can save about 2188.91 tons of standard coal for the grid every year compared with the thermal power plants with the same power generation capacity. At the same time, the newly installed back-pressure steam turbine generator set also improves the efficiency of thermal energy utilization, and the annual power generation can reach 147 million kWh.
"Now we need to go from being a producer of carbon emissions to a controller of carbon emissions and a user of carbon dioxide." Hao Jinming said that in the development process of the domestic petrochemical industry, carbon peaking and carbon neutrality are a completely new topic, which means that professionals engaged in chemical work need to supplement contemporary expertise in carbon emission management.
According to relevant statistics, chemical industry, electric power, steel, building materials, non-ferrous metals, metallurgy, transportation, etc. are key industries in carbon emissions, and the sum of their carbon emissions exceeds 74% of the total national carbon emissions, the task of carbon emission reduction is heavy and difficult, and the need for enterprises to strengthen carbon emission management is urgent. Similarly, in Tianjin Dagu Chemical Co., Ltd., Yang Jiwei, a carbon emissions administrator, is checking the energy consumption of the previous day in front of the energy online monitoring system, "As long as the daily and monthly factories report some data, the background can automatically calculate the energy consumption equivalent and other information, which can realize the real-time tracking of emission data." Yang Jiwei said that excellent carbon emission administrators must not only calculate accurately, but also put forward relevant suggestions for carbon emission management to enterprises, and excavate carbon emission reduction measures with implementability.
In addition to his daily work, Yang Jiwei still maintains good learning habits, "Our position is more comprehensive, so we must constantly communicate new technologies with our peers and suppliers." Under the impetus of Yang Jiwei, Dagu Chemical's compressed air system transformation project is in the construction stage, "the new compressor can be more efficient and the frequency conversion control system can have high energy efficiency under different load conditions, so that it can operate in the economic load zone and meet the additional gas demand." ”
In addition, the zero-air consumption blower heat dryer built with this project also reduces the loss of the transition from compressed air to dry air, and also reduces the power consumption of compressed air, Yang Jiwei visits the site every day, "According to the results of the previous data survey, the two projects are expected to save 7 million kWh of electricity per year, saving 6190 tons of carbon dioxide emissions." ”
The abs resin plant has a production capacity of 400,000 tons per year in the Lingang plant, and "ABS resin can be applied to all aspects of our lives, including automotive interiors, electrical housings, and even manufacturing industries such as textiles, aircraft, and ships, as well as the chemical industry." Yang Jiwei said that due to the large scale of the device, the task of energy conservation and emission reduction is heavier, Yang Jiwei introduced, "I have held 5 meetings with suppliers to discuss, organized the transformation of ABS circulating water system energy-saving technology, and now the equipment is about to be in place, and the actual circulating water consumption is more matched, reducing electricity consumption, thereby reducing indirect emissions." ”
Tianjin Dagu Chemical Co., Ltd. has also made in-depth explorations in accelerating the layout of the new energy industry and energy recycling and recycling, and organized the construction of energy-saving and carbon-saving projects such as residual liquid waste heat recovery and energy-saving transformation of hot oil furnaces, which can reduce carbon dioxide emissions by 1488 tons and 3762 tons respectively. Ning Jiwei, deputy director of the Planning and Development Department, said, "In 2019, the Ministry of Industry and Information Technology of the People's Republic of China rated our Lingang factory as a national -level 'green factory', and completed the carbon footprint assessment of styrene products. ”
According to relevant statistics, a person who emits at least 50kg of carbon dioxide a day in food, clothing, housing and transportation needs to plant 1,000 trees to absorb it. At present, carbon emission management as an emerging profession is in its infancy, but their existence allows us to see the efforts of the entire industry, the whole country, in order to protect the blue sky, in order to protect the earth. "The industry itself is a very meaningful industry, and our purpose is to strive for a better living environment for all mankind." Yang Jiwei said firmly.
