Process description of small-scale inner compression air separation plant

Eliminated from mechanical impurity by the air filter, the required amount of process air is compressed by air compressor to rated pressure. Afterwards, it goes into water-cooling tower for cleaning and pre-cooling. The removal of harmful components, such as moisture, CO2, C2H2 are carried out by activated alumina and molecule sieve in molecule sieve purifier, which will automatically alternate. After purification, compressed air goes into main heat exchanger, and cooled down to its dew point temperature.  Afterwards, it goes to lower column for primary rectification. In lower column, gas nitrogen is got the top of lower column, and then condensed into liquid nitrogen in evaporator-condenser. Part of liquid nitrogen is sent back to lower column as reflux. Balance liquid nitrogen and

Process description of gas air separation plant

Eliminated from mechanical impurity by the air filter, the required amount of process air is compressed by centrifugal air compressor to ~0.5MPa. Afterwards, it goes into water-cooling tower for cleaning and pre-cooling. The removal of harmful components, such as moisture, CO2, C2H2 are carried out by activated alumina and molecule sieve in molecule sieve purifier, which will automatically alternate. After purification, small stream of compressed air is compressed secondarily by booster end of turbine. Through cooling via water cooler, it goes into main heat exchanger for secondary cooling. Then it is drawn from middle part of heat exchanger to expander of turbine. Afterwards, expanded air is sent to upper column for rectification. After purification, large stream of compressed air is cooled

Liquid nitrogen usage in industry, biology and medicine

Industrial use: In industrial production, through the liquid compressed air fractionation method to obtain the liquid nitrogen, can be used as a depth refrigerant, due to its chemical inertness, can directly contact with biological tissue, frozen immediately and won’t destroy biological activity. Quickly freeze and transport food, or make ice products. Study on low temperature physics. Demonstrate low temperature state in science education.Soft objects soak in liquid nitrogen in normal temperature, which can be as brittle as glass. Provide the temperature of superconductivity of high temperature superconductor. Refrigerant can be used to quickly freeze biological tissue to prevent the tissue from being destroyed. Used for industrial nitrogen fertilizer manufacturing. Used for chemical testing, such as BET ratio surface area test
