Recently, our company has received exciting news in the field of high-purity gas technology: a supercritical ultra-high-purity carbon dioxide purifier has been successfully developed and put into use. This equipment can purify multiple impurities in carbon dioxide to an extreme level below 10ppt.
This technological breakthrough marks that our company has entered the international ranks in the field of high-purity gas purification, providing solid technical support for numerous fields such as semiconductor chips, high-end manufacturing, and scientific research experiments.
According to the R&D team, this purifier adopts multiple innovative technologies. This purification accuracy is equivalent to the number of impurity molecules not exceeding 10 among trillions of gas molecules, almost reaching the theoretical limit of purification technology.
Technological innovation has overcome multiple challenges in ultra-high purity purification
To achieve the ultimate purification of carbon dioxide under supercritical conditions, a series of technical problems need to be solved. The R&D team has broken through the limitations of traditional purification techniques and adopted innovative technologies such as multi-stage purification and supercritical fluid precision purification.
The core of the purification system lies in its ability to maintain the supercritical fluid state of carbon dioxide and capture trillions of impurities in the supercritical fluid. It adopts a dual-system configuration of one in use and one as a backup to ensure the continuous and stable operation of the purification process.
During the regeneration stage, through precise fluid control and multi-band heating control system technology, impurities are efficiently removed, ensuring the stability of the purified quality.
In addition, the team has developed ultra-high-performance adsorbents, which have extremely high adsorption selectivity and capacity and can specifically remove trace impurities from supercritical carbon dioxide.
For the purification of small-flow gases, the team specially designed a special purification device. By optimizing the filling ratio of granular and powdered adsorbent materials in the metal pipeline and controlling the temperature gradient, a purification effect with an extremely low impurity level was achieved.
It has a wide range of applications and meets the development needs of high-end industries
The launch of this supercritical ultra-high-purity carbon dioxide purifier will meet the extreme requirements for gas purity in multiple high-end industries.
In the field of semiconductor chip manufacturing, high-purity gases are the key to ensuring the yield and performance of chips. Any trace impurities may cause chip defects. As the chip manufacturing process continues to shrink, the purity requirements for process gases are also getting higher and higher.
Supercritical carbon dioxide cleaning technology has become a key process in semiconductor manufacturing, and the purity of the cleaning agent directly determines the cleaning effect and the yield of the product.
In emerging industries such as compound semiconductors, photovoltaics, and optical fibers, high-purity carbon dioxide is also an indispensable process gas.
In addition, the medical and scientific research fields also have a strong demand for high-purity gases. For instance, when Yaguo Biomedical develops biomedical materials using supercritical carbon dioxide fluid technology, the core of its technology lies in an efficient and pollution-free purification process.
In energy systems, such as the supercritical carbon dioxide Breton cycle power generation system, the purity of the working medium is directly related to the safety and efficiency of the system.
The prospects are broad, promoting industrial upgrading and technological innovation
The successful development of this supercritical ultra-high-purity carbon dioxide purifier not only broke the foreign technological monopoly but also provided key technical support for the upgrading of China's manufacturing industry.
With the advancement of the "carbon peak and carbon neutrality" strategy, the capture and resource utilization of carbon dioxide have received increasing attention.
High-purity carbon dioxide purification technology will open up new ways for the high-value-added utilization of carbon dioxide and promote the development of low-carbon and green technologies.
The R&D team stated that in the next step, they will continue to optimize the energy efficiency and stability of the purifier, further reduce operating costs, and at the same time develop a series of products suitable for different scenarios to meet the needs of various users.
In the future, this technological platform is also expected to be extended to the preparation of other high-purity gases, providing more comprehensive basic material support for the development of China's high-tech industries.
With the rapid development of the semiconductor industry, new materials, new energy and other fields, the demand for ultra-high purity gases will continue to grow. The breakthrough progress of this technology not only enhances China's independent capacity in the supply of high-purity gases, but also provides a guarantee for the safety and stability of the entire high-tech industrial chain.
In the future, the R&D team will further optimize the system performance and expand the application fields, injecting new impetus into the development of China's high-end manufacturing industry.
