Liquid Oxygen Plant

We are a leading company for manufacturing and supplying liquid oxygen plants, which are technologically very advanced and high performing. Come out in capacities ranging from 50 m³/hr (70 liter/hour) to 500 m3/hr (700 liter/hour), the machines work in compliance with the machines of North American and European Pharmacopoeia standards. The purity is also perfect for different industrial and medical applications. We manufacture the plants in small, medium and large capacity in order to meet the requirement of everyone.

Widely applicable in a number of industries for instance water process, ferrous metallurgy, non-ferrous metal refinery, coal mines and pharmacy, the products can be availed at industry leading prices. Huge discounts are provided time after time in order to retain existing customers and convince potential ones. Before supplying, the machines are checked carefully in order to shun any problem at our clients’ site. Our technicians and engineers provide commissioning, erection, installation and training services in the best manner.

Liquid Oxygen plants

Our liquid oxygen generation machines are designed and manufactured keeping in mind industry requirements. We focus on technology ensuring the outputs from the plants do not lack. Since our inception, we have served a long list of satisfied customers located over 40 countries. We have our customers located in Nigeria, Iraq, Iran, Egypt, Yemen, South Africa, UAE, UK and the list goes on.

Basic Principle :

  • The oxygen nitrogen plant recovers oxygen and nitrogen from air simultaneously via Low pressure cryogenic distillation process.
  • The design is based on an Italy company using rotary screw compressor and turbo expanders.
  • The feed air enters the Molecular Sieve purification unit where impurities such as moisture and CO2 are removed from the process air.
  • The air is liquefied by cryogenic cooling using advanced plate and fin along with highly efficient heat exchangers and turbo expanders.
  • The air separates into oxygen & nitrogen in the air separation column with final product being sent for pipeline application or stored into cylinders at the required pressure.

Process description :

Air compressors to compress atmospheric air: We offer advanced and fully automatic air compressors to compress the atmospheric air. The compressors come out with inbuilt air suction filter to suck air and leave behind the impurities, which are mixed with the air.

Features of our air compressors :
  • Oil free
  • Water free
  • Energy efficient
  • Fully automatic

Process skid/air purification unit to purify the compressed air: Even after trying a lot, there are some impurities mixed with the air get inside the process. The process skid eradicates the impurities for instance carbon dioxide, moisture and so on.

Expansion engine/expander to cool the air down: Once the atmospheric air gets compressed and purified, now it is time for cooling. Reason being, it is easy to separate oxygen and nitrogen in the liquid form. The -165 degree centigrade temperature is considered as perfect temperature for separation.

Air separation unit/column to separate :Oil free moisture free and carbon dioxide free air reaches to the column. They are capable to taking the air to -165 to-170 deg C. In such a temperature, the air becomes liquid and thus easily separable.

Cylinder filling manifold to fill in cylinders: After air separation, the oxygen and nitrogen is sent to the cylinder filling manifolds. They with the help of liquid oxygen pumps fill in cylinder at the pressure of 150 to 160 bar.
