【Ten Years of Rapid Development in Chemical Processing Equipment】Core compressor equipment for Asia’s largest coal-fired CCUS project, 1994–2023
Thread Content
Ten years of rapid development in chemical processing equipment – praise for China’s prosperity and strength. This is just a starting point; more participation will make things even more lively. HaiChuan becomes even better with you here; we welcome everyone to join in the forum discussions. Everyone should pay attention to safety and know how to handle emergencies. ********************************************* On June 2nd, **Energy Group’s 500,000 tons per year CCUS project successfully completed its full-load trial operation and was put into formal operation. Shaanxi Blower (Group) Co., Ltd. (referred to as “SHANXI BLOWER”) provided the core compressor equipment for carbon dioxide capture, as well as system solutions and services for this project. The project captures 500,000 tons of carbon dioxide per year; it is currently the largest coal-fired CCUS project in Asia. The heat consumption for capturing each ton of carbon dioxide is less than 2.4 GJ, and the electricity consumption is less than 90 kWh. The carbon dioxide capture efficiency is over 90%, with the purity of the dry carbon dioxide produced exceeding 99%. The successful commissioning of this project marks the growing maturity of China in large-scale coal power CCUS technology, laying a solid foundation for future larger-scale carbon dioxide capture and utilization efforts. At the same time, while ensuring profitability, this project achieves full utilization of carbon dioxide, which will accelerate the transition of coal-fired power CCUS from a technological demonstration phase to industrialized, clustered development. It is understood that this project uses the flue gas from the wet electrostatic precipitator of Unit 4 at the Taizhou Power Plant of the Energy Group in Jiangsu as the feed gas. The alcohol amine absorption method is employed to capture, store, and utilize carbon dioxide generated by coal combustion, and by taking advantage of the local resources available, this carbon dioxide is transformed into useful resources and utilized as an energy source. **Jiangsu Taizhou Power Plant, which belongs to an energy group, used an inquiry-based approach to enter into sales contracts with eight distributors for 40,000 tons of carbon dioxide per month. Sales are carried out through a distribution model: approximately 290,000 tons is used for dry ice, about 170,000 tons for welding shielding gas, and 20,000 tons for other purposes. An additional 20,000 tons is being used for research on oil displacement in oil fields.
This CCUS system at Taizhou Power Plant captures and purifies 500,000 tons of carbon dioxide each year, of which 100,000 tons is of food-grade quality and 400,000 tons is of industrial-grade quality. The project has also successfully developed customers in areas such as oil field flooding, welding and manufacturing, food-grade dry ice, and advanced mechanical cleaning, thereby ensuring 100% utilization of the captured carbon dioxide. In the early stages of project construction, Shaanxi Gas Turbine utilized advanced global pneumatic calculation techniques for compressor design. Through optimizations of the main engine model and the sealing system, as well as improvements to the unit’s flow mechanisms and intelligent control systems, it was possible to reduce compression energy consumption by 10% compared to traditional approaches. The long-term operational stability of the engine was significantly enhanced, resulting in the entire system featuring high capture efficiency and product purity, low energy costs for capture and carbon removal, and a reduced need for operating staff.
