Chenrui Cryogenic Nitrogen air separator plantChenrui cryogenic high purity 99.997% Liquid Nitrogen Production Plant Making Machine hydrogen fuel cell electricity generator
Cryogenic air separator plant principle
Air liquefaction by turbo expander refrigeration cycle principle.According to the different liquefaction point of oxygen and nitrogen,we get high pure nitrogen gas (nitrogen purity 99.99%)and oxygen gas(oxygen purity 99.6%after second rectification.It also could get some liquid gas.Acoording the principle of molecular sieve absorb,cooling by gas expender,single tower rectification,get both nitrogen gas and liquid nitrogen.Capcity and pressure could as user's requirement.

1). Full Automation
All systems are designed for un-attended operation and automatic Nitrogen demand adjustment.
2). Lower Space Requirement
The design and Instrument makes the plant size very compact,assembly on skids,prefabricated from factory.
3). High Reliabiity
Very reliable for continuous and steady operation with constant Nitrogen purity.Plant availability time is better than 99% always.
4). Molecular Sieves life
Expected Molecular sieves life is around 25-years i.e. whole life time of nitrogen plant.So no replacement costs.
5). Adjustable
By altering flow,you can deliver nitrogen with precisely the right purity.
