Liquid Nitrogen Plant

Product Description

We, Universal Industrial Plants Mfg. Pvt. Ltd., manufacture and supply liquid nitrogen plant. The design of this plant is made in technical collaboration with ING. L. & A. Boschi, Italy, a company whose specialization lies in the development of small, medium and large capacity liquid nitrogen plant. This plant generates high purity liquid nitrogen, while maintaining the steady flow, all because of the high efficiency heat exchangers, cryogenic construction material and cross flow trays. The superior designing and cutting-edge cryogenic technology based liquid nitrogen plant can achieve purity, from 99.9% up to 99.999%, or PPM according to the requirement and application of the end user. This plant is offered in several capacities, from 10 Liters/Hour to 3000 Liters/Hour.

PRODUCT DESCRIPTION:

Atmospheric air compression : Air compressors (screw/centrifugal type) compress air at a very low pressure of 5-7 bar (kg/cm2).

Pre cooling system: The second process stage makes use of low pressure refrigerant for pre cooling the air compressor generated warm processed air to temperatures around 5-10 degrees Celsius, before it reaches the purifier.

Air purification by purifier : Purifier comprising alternatively functioning twin molecular sieve driers, purifies the low temperature air. The process air is separated into carbon dioxide and moisture, before it enters the air separation unit.

Cooling of air by expander : Liquefaction and cryogenic refrigeration is achieved by cooling air below the sub zero temperatures. Air is cooled below -165 to -170 temperatures by a highly efficient expander.

Separation of liquid air into oxygen and nitrogen by air separation column : The dust, moisture, carbon dioxide and hydrocarbons free air enters into fin type heat exchanger, where expander through air expansion process cools down the air below sub zero temperatures. In the air separation column, the air becomes liquefied and separated into nitrogen and oxygen by rectification process. Nitrogen generated can be up to 99.9% to 99.9999% pure, based on the requirement of the end user.

Liquid nitrogen is filled in liquid storage tank : Liquid nitrogen is filled for storage in a vacuum insulated cryogenic storage tank, connected to the air separation column outlet through insulates/vacuum pipe, creating an independent unit where attention of operator is not required.
