Oxygen Generation System With PSA/VPSA
Oxygen is the important industrial gas,widly used for the industry
of steel, non-ferrous metal,chemical, Energy Saving Furnaces,
environmental protection(sewage disposal, burn away the refuse
etc), glass, paper making, medical treatment etc. Oxygen generation
system with PSA/VPSA now becomes a new oxygen gerneration
technology with its lower cost and extensive used.
Operational Principle Of The Oxygen Generation System with VPSA
This equipment use the process of vacuum pressure swing
adsorption(VPSA for short), adsorb the nitrogen from the air with
molecular sieve, separate and collect oxygen, create oxygen
enrichment of 90-95% ,meanwhile,it can output the analysis which
contain the nitrogen and other impurity gas, this is usually
excluded into the atmosphere.
Technology a revolution in Non Cryogenic Air Separation and
Oxygen Generation Technology uses special grade of ZMS ( Zeolite
Molecular Sieve).
The compressed air is passed through a Twin Tower PSA module
interconnected with automatic
changeover valves. After passing through a Refrigerated Dryer air
gets dried. Dried compressed air
will now come in contact with bed of Zeolite molecular sieves
(ZMS). Zeolite Molecular Sieves are special
grade of adsorbent which have the property of preferential
adsorption of nitrogen molecules.
At a time one tower remains under nitrogen production cycle,
whereas the other tower undergoes
regeneration
which is achieved through depressurization of the tower to
atmospheric pressure. The outgoing oxygen
gas is sent to a surge vessel where the minimum pressure will be
maintained with the help of Back
pressure Regulator
