Lanshi Heavy Equipment has completed and delivered eight key pieces of equipment for China National Petroleum Corporation’s million-ton carbon capture project in Xinjiang. Recently, the eight critical devices for this carbon capture component of the 2.64-million-kilowatt new energy project, along with the associated coal-fired power generation and carbon capture facilities (Phase I), including CO2 separators, amine stripping tanks, lean liquid flash tanks, and rich liquid filters, were all completed and handed over by Lanshi Heavy Equipment. This project employs a chemical absorption process; the captured CO₂ will be used for oil displacement and storage in oil fields (CCUS-EOR), which helps to increase production and efficiency in Xinjiang’s oil fields, thereby achieving a closed-loop system for \"carbon capture, utilization, and storage\". The 8 key pieces of equipment provided by LANSHI Heavy Equipment for this project form a complete carbon capture process flow. By leveraging core technologies such as efficient separation, energy recovery, and system optimization, a carbon capture system with a capacity of millions of tons per year has been created that features low energy consumption, high efficiency, and high reliability. During the manufacturing process, Lanshi Heavy Equipment focuses on customer needs, coordinates various resources, and details the schedule for different stages. Manufacturing sites such as the Xinjiang company and the mobile factory branches work closely in coordination with relevant departments, keeping track of project progress throughout the entire process, continuously optimizing production procedures, strictly controlling key milestones, and maintaining high standards for safety and quality. All stages of production are seamlessly connected, enabling efficient progress. At present, 6 units including CO₂ separators, manufactured by the Xinjiang company, have been delivered; the lean liquid flash tank and rich liquid filter, produced by the mobile factory branch, are in the final stages of pressure testing. As China National Petroleum Corporation’s first carbon capture demonstration project on a scale of one million tons, and also the largest integrated project of \"new energy + coal power + CCUS\" in the country at present, it will be able to reduce CO₂ emissions by 1 million tons per year upon completion, achieving a win-win situation of both emission reduction and increased production. Lanshi Heavy Equipment will make full use of its advantages in providing comprehensive solutions for energy equipment, and through high-quality energy equipment and services, it will contribute to China National Petroleum Corporation’s green and low-carbon transformation as well as the achievement of the \"dual carbon\" goals.
The integrated coal-power carbon capture project at the Xinjiang Oilfield is China National Petroleum Corporation’s first million-ton-scale flue gas carbon capture project aimed at supporting the \"low-carbon, green, and economic\" strategy as well as the low-carbon development of the Xinjiang Oilfield. It is also the second million-ton-scale flue gas carbon capture project of its kind in China. In February 2025, CNPC (Xinjiang) Petroleum Engineering Co., Ltd. and China National Petroleum Engineering Corporation formed a consortium to win the bid for the EPC general contract for carbon capture in Phase I of the 2.64 million kilowatt new energy project, along with the associated coal-fired power generation and carbon capture facilities, in the Xinjiang oil field. The 2.64 million kilowatt new energy project in Xinjiang Oilfield, along with the associated coal-fired power generation and carbon capture facilities, is divided into two phases; this phase involves the construction of a carbon dioxide capture unit with a capacity of 1 million tons per year. Upon completion of the project, carbon dioxide flooding will enable an increase in oil production of 314,500 tons, which will significantly boost the recovery rate of existing oil fields and extend their operational life. It will also contribute to the development of the regional energy industry and the improvement of the energy consumption structure, achieving both the benefits of \"low-carbon production increases\" and \"resource recycling\".
This project employs a chemical absorption process, in which a specially designed CO₂ absorbent is used to capture CO₂ from coal-fired flue gas, and high-purity CO₂ gas is recovered from the absorbent through heating and regeneration. Through systematic comparison of various processes, the energy consumption required for the regeneration of this device can be kept at less than 2.25 GJ/tCO₂, which represents a reduction of about 15% compared to traditional processes; this sets a new benchmark for carbon capture technology in domestic coal-fired power plants. The captured carbon dioxide will be used for oil displacement and storage in oil fields (CCUS-EOR), which can help increase production and efficiency in the oil fields in Xinjiang, thereby achieving a closed-loop system for \"carbon capture, utilization, and storage\". Once the project is completed, the 1 million tons of carbon dioxide captured each year will help the Xinjiang oil fields achieve both low-carbon production increases and resource recycling, thereby creating a replicable low-carbon technology model known as the ‘Xinjiang model’ – one that can contribute to energy security and the achievement of the ‘dual carbon’ goals through petroleum-based solutions. The project works in close coordination with the currently under-construction 2*660,000-kilowatt coal-fired power projects; by using renewable energy to power carbon capture devices, it creates a closed-loop system for energy production and carbon reduction, thereby significantly reducing CO₂ emissions from coal-fired units. Guided by the principles of source and sink matching, ensuring diversification of gas sources, and prioritizing economic benefits, Xinjiang Oilfield Company boasts unique advantages in terms of reservoir resources. According to geological projections, the western part of the Junggar Basin holds great potential for oil reserves, encompassing 16 high-potential reservoirs with geological reserves amounting to 220 million tons. “By the end of the 15th and 16th five-year plans, the carbon purchase demand in the western part of the Junggar Basin will be 2.33 million tons and 3.73 million tons respectively. According to the \"Xinjiang Oilfield Ten-Million-Ton CCUS/CCS Development Plan,\" the total length of the pipelines in the western region is 110 km, with a designed annual transport capacity of 3 million tons. “During the 14th Five-Year Plan period, a pipeline will be constructed connecting Kezhou Petrochemical Plant, Area 8, Baikouquan, and Fengcheng; the length of this main pipeline is 110 km, with a designed transport capacity of 3 million tons per year (for two-way transportation). It is expected to be completed around the same time as the rest of the project. This facility will serve as the first station in Kezhou Petrochemical Plant for carbon pipeline transportation, delivering finished supercritical CO2 gas to the downstream sections of the pipeline.
