The advantages of deep cold air separation

Cryogenic air separation nitrogen production uses air as raw material, which is compressed, purified and heat exchanged to liquefy gas air into liquid air. Liquid air is mainly a mixture of liquid oxygen and liquid nitrogen. Liquid oxygen and liquid nitrogen have different boiling points and are separated by distillation to obtain nitrogen. 1. Air compression and purification The air passes through the air strainer to remove dust and mechanical impurities, then enters the air compressor, compresses to the required pressure, and then goes to the air cooler to reduce the air temperature. It then enters the air drying purifier to remove moisture, carbon dioxide, acetylene and other hydrocarbons from the air. 2. Air separation The purified air enters the main heat exchanger in the air separation column, and is cooled to the saturation temperature by the reflux gas (production nitrogen gas, waste gas), and is sent to the bottom of the distillation column. The nitrogen is obtained fr

PSA gas separation technology in small air separation unit   In recent years, pressure swing adsorption (PSA) gas separation technology has been widely used in petroleum, chemical, steel, metallurgy, electronics, medical and environmental protection fields due to its easy operation, room temperature operation, low energy consumption, high degree of automation and environmental friendliness. The core of the VPS device is the adsorbent, a significant feature of the adsorbent is that the ads...
