Oxygen Gas Plants

Universal Boschi is a world renowned name in the field of manufacturing and exporting oxygen gas plants, liquid oxygen plants and oxygen/nitrogen plants. Our company is associated with ING. L. & A. BOSCHI of Italy in order to incorporate the best technology along with design and drawing in its products. Atmospheric air mainly consists of oxygen and nitrogen gases along with small quantities of water, Carbon Dioxide, Argon, Helium, etc. is used. Oxygen and Nitrogen from the Air are separated due to difference in boiling points by distillation through a fractional column.

The atmospheric air is sucked in by a Rotary Air Compressor through a filter and is compressed to the design pressure. The compressed Air is then passed through inter-coolers, chilling unit, Moisture Separators, and then to the Molecular Sieve Battery for removal of Carbon Dioxide, Hydrocarbons and Moisture from the processed Air. This pure Air then passes through the 1st Heat Exchanger, where it is cooled by the outgoing Nitrogen and Oxygen. Part of this cooled Air is passed through Expander and the other part through the 2nd Heat Exchanger.

Oxygen Gas Plant Oxygen Cylinder
The column consists of two parts - the lower column and the upper column. There is a condenser in between the lower and upper columns, which acts as a reflux for the lower column and as a re-boiler for the upper column. The liquid at the bottom of lower column separates through the trays to give crude Oxygen at the bottom and approximately 90% pure Nitrogen at the top. Crude Oxygen termed as rich liquid is then expanded through an Expansion Valve from the lower column to the middle of the upper column. Crude Nitrogen termed as plant is expanded through another Expansion Valve from the top of the lower column to the top of the upper column. Due to difference in the boiling points, the pure Nitrogen boils over and accumulates at the top of the upper column and pure Oxygen, which accumulates at the bottom of the upper column.

Both Nitrogen and Oxygen are removed through separate paths in Heat Exchangers, for cooling the incoming air. Oxygen is compressed to a pressure by a stainless steel vacuum insulated liquid pump and is directly filled into cylinders. Nitrogen is however available and the same can be compressed. All our plants can have filling of Nitrogen gas (PPM Grade) in cylinders by an additional filling system and withdrawal of liquid Nitrogen.

Our oxygen gas plant is acknowledged across the globe for its features like reliable performance, high speed, sturdy construction and durable finish standards. These products are available in various specifications to meet the demands of various industries.
