Tonnage Oxygen/Nitrogen/Argon Plant


Tonnage oxygen, nitrogen and argon plant of our company is big sized plants, which are manufactured to generate oxygen, nitrogen and argon in both formats gases and liquids. The capacity of the plants starts from 50 m3/hr to 10,000 m3/hr and generate oxygen and nitrogen with purity upto 99.7% and 99.99% respectively. Since our inception, we customized tonnage oxygen, nitrogen & argon plant solutions the world over and designed and built a number of such plants. We have international collaboration to manufacture and design our tonnage plants to meet individual customer requirements. We also offer prefabricated solutions and can be delivered as packaged units all over the world.

With the passage of time, we have developed our technology and started offering pre-engineered solutions, using a modular platform to configure tonnage liquid oxygen, nitrogen and argon plants for individual customer needs. This particular method enables us to offer highly competitive solutions and expedite project execution. We, along with our international collaboration, have also become a leader in the design and construction of very large plants. We recently secured contracts to build and install world-scale machine in USA, UK, Yemen, Nigeria, Qatar and China.

Basic Principle

The air separation plant is plant recovering oxygen and nitrogen from air simultaneously. It advance low pressure technology process of Boschi Italy using Rotary screw compressor(or low oil free piston compressor) and turbo expanders.
The feed air entering the Molecular Sieve purification system employed to remove the moisture and CO2 from the process air. The air is liquefied by cryogenic cooling using latest plate and fin high efficiency heat exchangers and turbo expanders. The liquid air separates into oxygen nitrogen and insert gases in the air separation column.

PROCESS DESCRIPTION

Air Compressor-Low Pressure:- Air is compressed at a low pressure of 5-7 bar (0.5-0.7mpa). Air can be compressed at such low pressure by trouble free rotary compressor (Screw/Centrifugal Type advanced technology is employed in lieu of old bulky piston compressor).

Pre Cooling System:- The second stage of the process uses a low pressure refrigerant for pre-cooling the processed air to temperature around 12 deg C before it enters the purifier.

Purification of Air by Purifier:- The air enters a purifier consisting of twin Molecular Sieve driers, working alternatively. The Molecular Sieves remove the Carbon dioxide & moisture from the process air before the air enters Air Separation Unit.

Cryogenic Cooling of Air By Turbo(Expander):- The air has to be cooled to sub zero temperatures for liquification & the cryogenic refrigeration & the cooling is provided by highly efficient turbo expander, which cools the air to temperature almost below -165 to -I 70 deg C.

Separation if Liquid Air Into Oxygen and Nitrogen by Air Separation Column:- Oil free, moisture free and Carbon Dioxide free air enters into low pressure plate fin type Heat exchanger where the air is cooled below sub zero temperatures by air expansion process in the turbo 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.

Air gets liquefied when it enters the air separation column & gets separated into oxygen & nitrogen by the process of rectification.

Liquid nitrogen is available at the outlet at purity of 99.9% to 99.99% or 3ppm as required. Nitrogen gas is available as required.

Final Product Liquid Nitrogen:- The final product in the form liquid nitrogen to fill in cryogenic liquid tanks for storage.
