Temperature swing adsorption (TSA) systems are widely used in industrial gas purification and air separation units for feed gas pretreatment. Efficient and stable moisture removal is a crucial step in ensuring the long-term safe operation of downstream adsorbents and equipment.
Recently, a customer inquired about suitable activated alumina grades for use in TSA units, employing activated alumina as a dehydration layer in conjunction with 13X molecular sieves to remove carbon dioxide and other impurities.
For this typical operating condition, Zibo Xiangrun Environmental Engineering Co., Ltd. recommends XR101 activated alumina, a product widely used in industrial gas dehydration and TSA pre-purification systems.
Why is activated alumina the preferred choice for dehydration in TSA systems?
Under TSA conditions, the adsorbent needs to withstand:
Frequent thermal cycles of adsorption/regeneration
High regeneration temperatures
Continuous airflow scouring and bed loading
Therefore, the adsorbent used in the H₂O removal layer must possess:
High water adsorption capacity
Good thermal stability and regeneration performance
High mechanical strength and low abrasion rate
Stable pressure drop performance over long periods of operation
Activated alumina, due to its high specific surface area, large pore structure, and strong affinity for water, has always been a mature and reliable choice for TSA dehydration applications.
ALUSORB-XR101 Activated Alumina – Designed for TSA Dehydration Applications
XR101 activated alumina is manufactured in-house by Zibo Xiangrun and is suitable for deep drying of industrial gases and TSA pre-purification systems. It maintains stable performance through multiple adsorption-regeneration cycles.
Main Technical Parameters and Features:
Strong moisture adsorption capacity, facilitating low dew point control. High compressive strength and low abrasion rate, reducing pulverization and bed pressure drop fluctuations. Good thermal stability and regeneration performance, suitable for long-term TSA operation.
In TSA systems, XR101 activated alumina is typically used as the first-layer dehydration adsorbent for efficient removal of moisture from feed gas, thereby protecting downstream 13X molecular sieves and extending the overall lifespan of the adsorption system.
