Gamma Skid Reliable Advanced Oxygen Concentrator is one kind of pressure swing adsorption (PSA) Oxygen Plant. It is ideal replacement of liquid oxygen and pressurized cylinder oxygen. It consists of Air Compressor, air treatment part, air tank, oxygen separator and oxygen buffer tank.Inside the oxygen separator, there are zeolite molecular sieve, it adsorb nitrogen and produce oxygen on the principle of pressure swing adsorption. Its principle is as photo below:
Skid Reliable Advanced Oxygen Concentrator Specification:
Oxygen flow: 1-300 Nm3/hr
Oxygen purity: 90-95%
Outlet pressure: 5-200 bars
Oxygen concentrator process flow
This system adapts patent processing flow of adsorber top gas inlet, bottom gas outlet, unequal pressure balancing, desorption at the middle. It has advantages of low air consumption and long lifetime molecular sieve, etc.
PSA Process flow description
There are two adsorbers with Zeolite molecular sieve. When cleaning compressed air enters the gas inlet of adsorber A, it flows to outlet, passing through Zeolite molecular sieve, N2.CO2 and H2O are adsorbed, produced oxygen goes out of adsorber outlet.
After some time, the Zeolite molecular sieve in adsorber A is adsorb-saturated. Compressed air is switched to adsorber B to adsorb N2 and produce O2, at the same time, Zeolite molecular sieve in adsorber A desorbs and regenerates itself. The desorption of molecular sieve is realized by vent valve. When empty air in adsorbers, the pressure inside quickly drops down to normal pressure and the adsorbed N2.CO2.H2O are desorbed.
To thoroughly regenerate Zeolite molecular sieve, product oxygen from adsorber outlet or oxygen buffer tank is used to blow out the remaining N2.CO2.H2O of adsorbers.
Before the switch between two adsorbers, there is a process of pressure equalization, it is used to promptly increase adsorption pressure and oxygen rate of recovery. Pressure equalization means connecting two adsorbers, let gas in one adsorber(to be desorbed) enter the other one(to be adsorb), then the two adsorbers can have equal pressure.
This system adapts unequal pressure equalization process, the oxygen rate of recovery is further improved, which reduces the energy consumption of the whole system.
Two adsorbers alternately adsorb, pressure equalize and regenerate to separate oxygen and nitrogen, this process constantly produces oxygen.
