China's first and Asia's largest industrial-grade carbon dioxide direct air capture device pilot test successfully

Recently, a major innovative equipment jointly developed by China Energy Construction Shanghai Co., Ltd. and Shanghai Jiao Tong University and has completely independent intellectual property rights-the first annual 600-ton carbon dioxide direct air capture (DAC) device "Carbon Trap CarbonBox" successfully passed the full-load reliability operation verification of a 100-ton module. A single module successfully captured 99% of high-concentration carbon dioxide directly from the air every year and exceeded 100 tons. It marks a major breakthrough in my country's direct air capture technology and fills my country's gap in the field of ultra-large-tonnage and high-concentration industrial-grade DAC engineering equipment. It is of great significance to promoting my country's realization of the "double carbon" strategy and energy green transformation.

DAC is an emerging carbon capture technology that can use low-carbon energy such as wind energy, solar energy, and geothermal energy to directly capture carbon dioxide from the air and achieve net negative emissions of carbon dioxide. CarbonBox adopts a completely independently developed high-performance capture device with high selectivity and rapid adsorption kinetics, which can efficiently capture carbon dioxide directly from air or emission sources with different concentrations, and directly output different concentrations of carbon dioxide according to back-end application requirements. CarbonBox's technological leadership is mainly reflected in focusing on the world-wide problem of high energy consumption and high cost of DAC. Through innovative design of the capture device structure, precise optimization of process flow and disruptive research and development of core supporting components, the R & D team has achieved carbon dioxide capture The design goal of energy consumption, while ensuring the reliability, safety and service life of the capture system, and the comprehensive performance reaches the international leading level. CarbonBox greatly improves system integration through the modular capture unit structural design, giving a high degree of system flexibility and on-site assembly efficiency. It can achieve rapid system replacement and convenient access to application scenarios, and enhances the capture device's use in various engineering applications. Universality under scenarios. A single CarbonBox system with an annual capture capacity of 600 tons consists of a capture unit and a processing unit. The size of each unit is the size of a 40-foot container. The module can be directly hoisted on site without secondary assembly; At the same time, the CarbonBox can also carry out the stacking of capture units and the centralized design of processing units according to engineering requirements. Through standardized group integration, the annual capture scale of carbon dioxide can reach one million tons.

CarbonBox can be widely used in fields such as green methanol and green jet fuel and carbon trading services. The carbon dioxide obtained through direct air capture by CarbonBox is a truly green and environmentally friendly carbon source that meets international ISCC certification. It can also overcome a series of application constraints such as unstable raw material supply and geographical restrictions, and achieve large-scale and stable green carbon sources. Supply, completely open up the carbon source bottleneck faced in the current green fuel synthesis. In addition, with the in-depth advancement and implementation of the national "double carbon" strategy, according to the carbon emission reduction and carbon trading needs of different enterprises and institutions, CarbonBox uses its modular design characteristics to be large-scale centralized, distributed and mobile. Layout, to realize carbon capture quotas, project emission reduction development, international carbon tariff response, zero-carbon construction, climate investment and financing and other services anytime, anywhere, and without regional restrictions, providing government agencies, group companies, High-carbon enterprises and others provide a package of "carbon neutrality" solutions.
