Specification of liquid nitrogen generator

Mixed-refrigerant Joule-Thomson (MRJT) refrigerator at low temperature ranges driven by single compressor with precooling is applied to liquefy nitrogen (-180℃) for Nitrogen Liquefier from TIPC, CAS. MRJT, a Joule-Thomson cycle based on reoccupation and multicomponent mixed-refrigerants through optimizing various refrigerants with different boiling points with a good match along with their respective efficient refrigeration temperature ranges, is an efficient refrigerator for the temperature range from -40 to -196℃. The feature of this product is as following: the available mature commercial compressors and heat exchanges, high liquefaction efficiency, high reliability, no maintenance and long life.

a. fish boat,hotel and food processing plant: food quick-freezing,Beverage processing
b. hospital and beauty salon:Liquid nitrogen refrigerating apparatus,Vaccine preservation
c. laboratory: transducer calibration,Specimen preservation
d. farm: Embryo freezing instrument,freezing spermatozoon

Principle of Operation
The oxygen and 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 or oxygen. 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.

Process Flow Brief Description

Technical Features
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). Fast Start-up
Start-up time is only 5 minutes to get desired Nitrogen purity.So these units can be switched ON&OFF as per Nitrogen demand
4). High Reliabiity
Very reliable for continuous and steady operation with constant Nitrogen 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 nitrogen plant.So no replacement costs.
6). Adjustable
By altering flow,you can deliver nitrogen with precisely the right purity.
