Air separation

   ZeoliteThe use of air separation can be made, including oxygen, nitrogen and rare gases, including a series of gaseous or liquid products, preparation methods, including low temperature distillation and PSA pressure adsorption method.
   Air purification system
   In the traditional low-temperature air separation, the moisture in the air, CO2 in the case of low temperature will freeze precipitation, blocking equipment and pipelines; hydrocarbons (especially acetylene) in the air separation plant in the aggregation, but also under certain conditions lead to an explosion The So these impurities need to be removed by an air purification system filled with molecular sieves before the feed air enters the cryogenic separation process.
   PSA nitrogen and oxygen separation

   Pressure swing adsorption air separation oxygen, nitrogen production process, because of its low investment, low energy consumption, easy operation, in the small and medium scale space field has replaced the traditional low-temperature air separation unit trend. Mainly the use of oxygen-specific zeolite in a certain pressure conditions, for the nitrogen and oxygen adsorption rate is different, so that the two gases can be separated from the characteristics of oxygen and oxygen-enriched air. For the lower pressure adsorption VSA and VPSA devices, the use of high efficiency oxygen with lithium zeolite, can further enhance the oxygen production rate and reduce oxygen consumption.
