BMO Membrane Separation Oxygen Generator

Working Principle

Membrane separation oxygen-making technology depends on the different permeability of nitrogen, oxygen, etc. in the air. When they are penetrating through the membrane, oxygen with rapid permeability permeates through the membrane first and become oxygen-rich gas so as to realize separation of oxygen and nitrogen; this method can get oxygen-rich gas as well as nitrogen through membrane method.

Technical Features

· Easy operation, reliable running, high automation, no moving part and no cyclical switch, so as to meet the requirement for long-term and continuous operation;

· Convenient and quick start on/shut down and produce qualified oxygen within short time after start on the machine;

· Low energy consumption and the degree of purity of oxygen can be continuously adjustable;

· There is no noise and pollution in the separation process and the purity of oxygen is high without any harmful waste;

· The oxygen production capacity can be expanded through increasing the amount of the membrane component, so as to meet the customers’ requirement for different quantity of output of oxygen;

· It has devices to detect and protect the quality of the entering air through the membrane component to ensure that the qualified air gets into the membrane component, so as to improve the service life of membrane;

· The machine is compact in structure, easy to install and small in size;

· It has wide applications and is resistant to many chemical pollutions;

·The remote monitoring system, automatic adjustment device of purity, DCS communication, etc. are optional.

Technical Indexes

·Oxygen purity in primary system: 35%~55%

·Oxygen purity in secondary system: ≤ 90%

·When the oxygen purity is about 30% and the scale is less than 1,5000 Nm3/h, the cost of investment, maintenance and operation in membrane method is only 65%~75% of the cost of cryogenic method and PSA method, furthermore, the less of the scale, the more economic of the membrane method.
