PSA Marine Membrane N2 Generator 1.0kw Liquid Oxygen Nitrogen Plant

Food Preservation Liquid Nitrogen Generator Mini Liquid Nitrogen Plant

The nitrogen generators are constructed according to the principle of operation P.S.A. (Pressure Swing Adsorption) and are composed by a minimum of two absorbers filled up with molecular sieve.The absorbers are crossed alternatively by the compressed air (previously purified in order to eliminate oil, humidity and powders) and produce nitrogen . While a container, crossed by the compressed air, produces gas, the other regenerates itself losing to pressure atmosphere the gases previously adsorbed. The process comes repeated in cyclical way. The generators are managed by a PLC.

Membrane Nitrogen Generator Application:

• Oil, gas: oil-refining, petroleum oil nitrogen injection exploitation, weather containers, pipelines nitrogen sweeping, leak detection, replacement, offshore oil exploitation.
• Mine: underground explosion prevention, coalfield fire prevention.
• Medicine: nitrogen filling storage of Chinese herbal medicine, nitrogen filling and oxygen discharging packaging of western medicine and injection, and drug material pneumatic transmission.
• Electronics: nitrogen protection in the processing of integrated circuits and semiconductor devices, purifying the treasury, drying and clean packaging.
• Food: nitrogen filling packaging, gas adjustment fresh storage of fruits and vegetables, nitrogen filling and oxygen discharging packaging of liquor and beverages and edible oil stir.

1). Full Automation

All systems are designed for un-attended operation and automatic Oxygen demand adjustment.

2). Lower Space Requirement

The design and Instrument makes the plant size very compact,assembly on skids,prefabricated from factory.

3). Fast Start-up

Start-up time is only 5 minutes to get desired Oxygen purity.So these units can be switched ON&OFF as per Oxygen demand changes.

4). High Reliabiity

Very reliable for continuous and steady operation with constant Oxygen purity.Plant availability time is better than 99% always.

5). Molecular Sieves life

Expected Molecular sieves life is around 15-years i.e. whole life time of Oxygen plant.So no replacement costs.

Characteristics

Compared with other on-site gas production methods, membrane air separation nitrogen Gas Generator and oxygen enrichment equipment has the following characteristics:

1). Advanced technology, is the latest technology of normal temperature air separation;

2). No noise, completely static operation, meet the requirements of environmental protection;

3). No moving parts, less equipment maintenance;

4). High reliability of continuous operation, long service life of equipment, up to more than 10 years;

5). Capacity increase is simple, only need to increase the membrane in parallel, increase the amount of raw material compressed air;

6) compared with PSA, air and nitrogen buffer tank can not be set, small volume, light weight, is the best choice for mobile nitrogen and oxygen production equipment;

7) nitrogen products have low dew point, which can reach -70℃ under long-term continuous operation conditions. ;

8) nitrogen products are clean, without any dust and particles;

9). Convenient and rapid start-up and shutdown, simple operation, can produce qualified nitrogen in a short time;

10). The form of equipment can be designed according to user's application requirements, can be box type, skid loading type or container type;

11). The equipment has no special requirements for civil construction and low installation cost;

12). No special requirements for the environment, can operate under bad conditions.
