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 […]
