93% PSA Oxygen Plant , Oxygen Cylinder Filling Plant ISO9001 Certification

2. Process Flow Brief Description

PSA oxygen generator is an automatic equipment which separate oxygen from air. According to the performance of molecular sieve, its adsorption when pressure risen and desorption when pressure loose. Molecular sieve’s surface and inner surface and interior are filled with micro pores. Nitrogen molecule has a faster diffusion rate of molecular sieve and oxygen molecules has a slower diffusion rate. Oxygen molecules are enriched in the end from the absorption tower.

Oxygen generator is constructed according to the principle of operation PSA (pressure swing adsorption) and it compressed by two absorption towers filled up with molecular sieve. The two absorption towers are crossed by compressed air (previously purified oil, water,dust, etc) . While one of the absorption tower produce oxygen, the other one release nitrogen gas to atmosphere. The process comes in cycle way. The generator is controlled by a PLC.

3. Oxygen Generator Applications

a. Ferrous metallurgy: For electric furnace steel making, blast furnace iron making, cupola oxygen blasting and heating and cutting, etc

b. Non-ferrous metal refinery: It can improve productivity and reduce energy cost, also protect our environment.

c. Water process: For oxygen aeration active mud process, reaeration of surface water, fish farming, industrial oxidation process, humid oxygenation.

d. Customized equipment with pressure high up to 100bar, 120bar, 150bar, 200bar and 250 bar are available for cylinder filling.

e. Medical-grade O2 gas can be obtained by equipping extra purifying device for removing bacteria, dust and odor.

f. Others: Chemical industry production, solid garbage burning, concrete production, glass manufacturing...etc.
