In March 2022, Gamma Gas celebrated a significant milestone: its self-developed invention patent, "Pressure Swing Adsorption Gas Separation Method and Device for Variable-Path Step-By-Step Pressure Equalization", was officially approved by the National Intellectual Property Administration (CNIPA) and granted an invention patent certificate.

Conventional pressure equalization methods typically complete the entire process in a single step with a fixed path, maintaining a constant pressure equalization channel. This approach often causes a significant reverse phenomenon in the gas purity curve within the adsorbent bed, making high-purity gas production challenging. In practice, achieving the desired purity usually requires sacrificing the device's production capacity, leading to increased energy consumption. Therefore,  reducing factors that negatively impact product gas purity is crucial.

To overcome these limitations, the present invention introduces a pressure swing adsorption (PSA) gas separation method and device featuring variable-path stepwise pressure equalization. By altering the pressure equalization path in stages, this innovative solution effectively reduces the reverse effect on gas purity, optimizing the utilization of the adsorbent bed. This not only enables the production of high-purity gas but also enhances the overall efficiency of the PSA process. As a result, it provides a viable technical approach for producing high-purity gas at a lower cost, marking a significant advancement in PSA technology.

This groundbreaking achievement is not only a powerful testament to Gamma Gas's long-term commitment to independent R&D and innovation, its deep focus on PSA technology, and continuous increase in R&D investment. It also represents a significant milestone on the company's journey towards becoming a technology- driven modern enterprise, marking a major leap forward in its technological innovation and core competitiveness building.
