Guohua Jinneng CCUS Project Author/Source: Gasification World Date: 2021-06-28 Clicks: 192 On June 25, the Guohua Jinneng CCUS Project, constructed by China National Chemical Engineering Corporation’s 10th Construction Company, successfully passed the 168-hour continuous full-load trial operation and was officially put into operation. The 150,000 tons per year CO2 capture demonstration project is currently the largest CO2 capture facility in China and boasts the best design performance indicators globally. It serves as a project to help China achieve its \"3060\" goals (carbon peak and carbon neutrality), as well as to serve as a model for the low-carbon and sustainable development of coal-fired power plants. On January 21, 2021, China’s largest full-scale demonstration project for carbon dioxide capture and storage with an annual capacity of 150,000 tons successfully received power at the Guohua Jinjie Power Plant of the **Energy Group, thus entering the commissioning phase. Project Overview: The project commenced construction on November 1, 2019, and was officially put into operation on June 25, 2021, after passing a 168-hour trial run. All performance indicators met excellent standards, and the project achieved eight successes from the first attempt: successful power supply to the system, successful DCS restoration test, successful cold-state ventilation, successful chemical cleaning, successful hot-state startup, successful full-system startup, successful product liquefaction, and successful loading and transportation. This project represents Guohua Power’s innovative efforts in the field of energy conservation, emission reduction, and low-carbon development. It was designated as a key construction project in Shaanxi Province for 2018, as well as a major scientific and technological innovation project for the group company. It also received support from the **Key R&D Program for ‘High-performance absorbents/adsorbent materials and technologies for CO2 capture’**. To successfully complete the construction of the largest post-combustion CCS demonstration project for coal-fired power plants in China, Guohua Power established a carbon capture project team led by its research institute and Jinjie Power Plant. The design was optimized on multiple occasions, making use of advanced chemical absorption processes as well as various energy-efficient techniques such as inter-stage cooling, split desorption, and MVR. Innovative applications were also made of equipment and materials such as high-efficiency low-temperature difference heat exchangers, supergravity reactors, and modified plastic packing. Once operational, the CCS demonstration project will be able to achieve a carbon dioxide capture rate of over 90%, a carbon dioxide concentration of over 99%, and a heat consumption for absorbent regeneration of less than 2.4 GJ per ton of CO2. Its overall performance indicators are at the international leading level, providing technical support for large-scale carbon capture in coal-fired power plants in China as well as for achieving the carbon reduction targets set out in the Paris Agreement. This technology is applicable to large-scale industrial production, offering significant environmental and social benefits, and can make an important contribution to China’s efforts to achieve carbon peak and carbon neutrality.
