Pressure Swing Adsorption (PSA) units are commonly used to separate and purify a wide range of industrial gases. Typically for syngas streams, the PSA unit is used to produce a pure hydrogen stream which can then be used in a variety of downstream processes including hydrotreating and hydrocracking applications. The resulting hydrogen stream can achieve purities of 99.999% hydrogen.
The PSA unit utilizes a timed cycle of steps of adsorption, pressure equalization, depressurization, blowdown, purge, and repressurization across multiple beds loaded with various types of adsorbent (activated alumina, silica gel, activated carbon, mol sieves). When a bed is on-line, the syngas flows upward through the bed where at normal operating pressure components are physically adsorbed while the preferred hydrogen flows through the unit. The bed is taken out of service and goes through a series of depressurizations where the adsorbed components are released. The released components are an offgas that is then typically used as a fuel in SMR units. The bed is then repressurized and returned to service.
XR101T Special Activated alumina adsorbent in PSA(Pressure Swing Adsorption) has high adsorption than XR101. It works as a desiccant through adsorption, so as air passes through the Activated Alumina beads, the water in the air sticks to it and becomes trapped, enabling the air that passes through the Activated Alumina filter to become dried out. Even if immersed in a liquid, it will not fall apart or soften. XR101T Special Activated alumina is white spherical porous particles, uniform particle size, smooth surface, high mechanical strength, and strong moisture absorption.
XR101T Special Activated alumina adsorbent in PSA is extremely effective in Pressure Swing Adsorption. XR101T Special Activated alumina adsorbent in PSA is a special adsorbent for pressure swing adsorption (PSA) gas separation devices. Pressure swing adsorption technology is widely used in petrochemical, chemical, metallurgical, environmental protection, food, electronics, aviation and other industries.
