【3D Process Flow】Summary Post – Useful for learning about the process flow: https://bbs.hcbbs.com/thread-5711616-1-1.html ---------------------------------------------------------- PSA (Pressure Swing Adsorption): PSA units are important gas separation and purification devices in the petroleum refining industry; they utilize the selective adsorption capacity of adsorbents for different gas components, and gas separation is achieved through pressure changes. In the petrochemical industry, PSA units are primarily used for hydrogen purification, natural gas purification, decarbonization, and other processes. Its working principle includes steps such as adsorption, depressurized desorption, and pressurized regeneration; multiple towers are typically used in a switching mode to achieve continuous and stable operation. The core equipment includes adsorption towers, programmable valves, vacuum pumps, compressors, etc., while the adsorbents are mainly activated carbon, molecular sieves, alumina, etc. PSA technology boasts advantages such as low energy consumption, simple operation, and a high degree of automation, making it an essential unit in modern refining facilities.
