As operating time increases, the adsorption capacity of activated alumina gradually declines. If not replaced in a timely manner, this not only affects the system’s dew point but may also lead to equipment corrosion, pipeline freezing, compromised product quality, and increased energy consumption. So, how can one accurately determine whether activated alumina desiccant has become […]
Different industries and operating conditions impose widely varying performance requirements on activated alumina powder adsorbents. An inappropriate product selection can lead to reduced adsorption efficiency, increased pressure drop, higher energy consumption, and even unstable equipment operation. How, then, should enterprises select the appropriate activated alumina powder adsorbent based on their actual operating conditions? This article […]
In industrial gas drying and adsorption systems, activated alumina is widely utilized—specifically in compressed air drying, natural gas dehydration, and PSA systems—due to its exceptional adsorption properties and mechanical strength. However, in actual operation, many users encounter two typical issues: · Severe pulverization (dusting) · Increased system pressure drop These issues not only compromise equipment […]

In industrial gas separation and purification processes, PSA (Pressure Swing Adsorption) systems are widely used in hydrogen production, oxygen production, nitrogen production, and gas drying. However, many users encounter a common problem in actual operation: decreased system efficiency, unstable gas purity, and continuously increasing energy consumption. Many people’s first reaction is to blame the equipment, […]
I. Why are membrane coating materials needed? In lithium-ion batteries, the membrane’s function is to isolate the positive and negative electrodes while allowing lithium ions to pass through. However, traditional polyolefin membranes (PE/PP) have significant problems: · Poor high-temperature resistance (shrinkage begins around 130℃) → prone to thermal runaway · Poor wettability → weak electrolyte […]
In natural gas purification processes, COS (carbonyl sulfide), a common organic sulfide, is widely present in natural gas, LNG, and refining gases. Due to its stable chemical properties and difficulty in direct removal, COS not only affects the performance of downstream catalysts but also corrodes equipment and can even lead to excessive sulfur content in […]
