At present, the main natural gas deep dewatering device at home and abroad is the use of synthetic fluorspar molecular sieves to strongly adsorb water vapor molecules in the gas to achieve deep dehydration.
Air pressure is less than 0.2MPa for household oxygen generator for adsorption process. Its working principle is as shown above, Skarstrom cycle with two layers(that is, two molecular sieve towers) oxygen generator is adopted and the working process is as follows:
In atmosphere almost 78% is Nitrogen (N2) and near about 21% Oxygen (O2) is there. To get Nitrogen from the air, PSA techniques is used by different industries as per their requirements. Carbon Molecular sieve is core part in the system of Pressure swing adsorption (PSA). As CMS has high affinity and capacity to adsorb the Oxygen molecules it can be used for Nitrogen generation.
