China’s largest demonstration project for carbon capture and storage (CCS) were successfully powered in Jinjie Power Plant of Guohua Power on January 21, marking that the project finished construction and entered a testing phase. The project has an annual capacity of 150,000 tons in carbon capture and storage.
The demonstration project for carbon capture and storage.
The project represents a new move in Guohua Power’s pursuit of energy saving, emission reduction and low-carbon development. It was recognized as a major technological innovation project by Shaanxi Province in 2018, and has received support from China’s National Key R&D Programs.
To build the demonstration project, the largest one in China, for capturing and storing carbon emissions from coal-fired power plant, Guohua Power set up a research task force consisting of members from its research arm and Jinjie Power Plant. The research team optimized the design plan for many times, adopted advanced chemical absorption method and integrated multiple efficient energy-saving processes including inter-stage cooling, shunt decomposition and absorption and MVR. On the basis, it originally used efficient low-end differential heat exchanger, high-gravity reactor and modified plastic padding among other equipment and materials.
After put into use, the CCS demonstration project will be able to capture and store 90 percent of carbon dioxide, the concentration of which will be over 99 percent. The absorbent regenerative heat loss will be lower than 2.4GJ/tCO2. With its overall performance reaches world leading levels, the project will provide technical support to China in fulfilling its carbon emission commitment under the framework of Paris Agreement. Used in large-scale industrialized production, the project will generate substantial environmental and social benefits and make a significant contribution to China’s carbon peak and carbon neutrality targets.
