Cryogenic Liquid Nitrogen Plants

We have emerged as the foremost engineering company renowned for manufacturing liquid nitrogen plants. We have the state of the art factory in New Delhi where we have got experienced engineers who manufacture premium quality liquid nitrogen plants using the best quality materials. Our manufacturing nitrogen plant is done in technical collaboration with ING. L. & A. Boschi, an acclaimed Italian company for fabricating of the industrial gas plant machinery. All the manufacturing processes at our factory are carried out in compliance with international standards. All components used in the fabricating nitrogen plants are thoroughly checked being used in fabrication.

Our liquid nitrogen plants are capable of nitrogen with purity up to 99.99%, which meets the requirements of all kinds of industries. Our LOX plants come in several capacities ranging from 20 Liter/hour to 1000 Liter/hour. The output is stored in liquid storage tanks. Quality of our manufacturing ensures that our machinery is known for their seamless performance, low power consumption, reliability and durability. We use advanced air separation columns for generating higher yield of oxygen. And for manufacturing our plant machinery in compliance with global standards, we have been awarded ISO 9008:20015 and CE.

 Scope and Supply

1. Air Compression : In the first stage, the air is compressed at a low pressure of 5-7 bar. Such low temperature is maintained by using advanced compressors.

2. Air Pre-Cooling : In the second stage, a low pressure refrigerant is used for pre-cooling the processed air to temperature around 12 degrees centigrade before it enters the purifier.

3. Purification of Air by Purifier : Air enters a purifier made of twin molecular sieve driers, each functioning in turn. The sieves eliminate the carbon dioxide and moisture from the process air before it enters the air separation unit.

4. Cryogenic Cooling of Air by Expander : Air is cooled to sub zero temperatures for liquefaction and cryogenic refrigeration. An efficient expander is used for cooling. Air is cooled to temperatures below -165 to -170.

5. Separation of Liquid Air into Oxygen and Nitrogen in Air Separation Column : Impurities such as oil, moisture and carbon dioxide are removed before air enters into a low pressure plate fin type Heat exchanger where the air is cooled below sub zero temperatures by air expansion process in the cryogenic expander. Due to the excellent thermal efficiency we can achieve a temperature difference delta t as low as 2 deg c at the warm end of these exchangers.

6. Liquid nitrogen stored in cryogenic liquid tanks : Liquid Nitrogen is directed from the cold box into the liquid storage tank, which is equipped with a pressure control panel. The control receives the signal for the demand for gaseous nitrogen and regulates the gas flow into the end-users pipeline to maintain line pressure. An ambient air vaporizer is used to vaporize stored liquid nitrogen.
