html On June 30, the domestic coal chemical carbon dioxide capture project with the lowest energy consumption and cost - Shaanxi Yanchang Petroleum Group Yulin Coal Chemical Company .3 million tons/year carbon dioxide capture device was installed in Yulin Officially put into operation.

CCUS (carbon dioxide capture, utilization and storage) is the current strategic leading technology to deal with global climate change and control greenhouse gas emissions. The key to its technology is to capture and purify the carbon dioxide produced in the industrial field, and then achieve carbon reduction through utilization and storage. Row. As an important national energy and chemical industry base, Yulin has oil and gas resources and coal chemical industry in the same place. It has unique advantages in implementing CCUS projects. The oil fields in the region have simple geological structures, stable strata, and undeveloped faults, making it an ideal place for geological storage of carbon dioxide.

It is understood that the 300,000 tons/year carbon dioxide capture device project of Yulin Coal Chemical Company of Shaanxi Yanchang Petroleum Group relies on the coal-to-methanol device and the high-purity carbon dioxide gas produced by the facility as raw materials. After compression, condensation and liquefaction, the production purity reaches 99.6% of liquid carbon dioxide products. All the captured carbon dioxide is used for carbon dioxide flooding and geological storage in Yanchang Petroleum Company's affiliated oil fields, realizing the coordinated and coupled development of manufacturing and mining industries, which can reduce carbon dioxide emissions by 300,000 tons per year. CCUS demonstration projects that have been put into operation in China still face the challenges of high energy consumption and high cost. According to public data previously released by the Ministry of Ecology and Environment, the lowest cost of carbon dioxide capture in the domestic coal chemical industry is 120 yuan/ton. Shaanxi Yanchang Petroleum Group Yulin Coal Chemical Company's 300,000 tons/year carbon dioxide project captures energy consumption of 1.36 GJ/ton, and the capture cost is only 105 yuan/ton. It is currently the lowest cost in China and will promote the scale and commercialization of CCUS technology in my country. The application is of great significance.

"Yanchang Petroleum has completed the overall planning of the 5 million tons/year CCUS project, and has incorporated its coal chemical projects into the CCUS industry chain to minimize the carbon dioxide emissions of the coal chemical production process, and at the same time use the captured carbon dioxide Focusing on oil flooding, fracturing and geological storage in low-permeability tight oil fields, we have embarked on a unique path of low-carbon transformation and green development for energy companies," said the person in charge of Shaanxi Yanchang Petroleum Group Company.

Shaanxi Yanchang Petroleum Group Yulin Coal Chemical Company’s continued efforts in energy conservation and emission reduction are a powerful attempt to explore and promote the realization of the “double carbon” goal in Yulin, a resource-based city. During the "14th Five-Year Plan" period, Yulin will promote low-carbon development as an important goal of accelerating green transformation, accelerate the establishment of a high-end low-carbon modern industrial system, advance the layout of carbon-neutral industries, and explore new low-carbon development options for "high-carbon cities" path.
