Oxygen Plant / Nitrogen Plant

The oxygen nitrogen gas plant are safe and economical & operate with an expansion engine which lowers the operating pressure up to 30-40 kg/cm, lowers the power consumption and is trouble free. The oxygen and nitrogen plant mainly consists of AIR COMPRESSOR (Innersole Rand) Molecular sieve battery for removal of acetylene and hydrocarbons from the process air and eliminating the use of caustic soda and cost saving as there is no need of any recurring cost of chemicals. The production plant can produce both OXYGEN & NITROGEN simultaneously and the plant BDM models have a Built-in internal compression liquid oxygen pump to fill bone dry high pressure oxygen up to 165 kg/cm in cylinders.

Process Description of BDM Oxygen Nitrogen Plant

The free atmospheric air is sucked in the nitrogen oxygen gas plants by a multi-stage air compressor through a filter and compressed to the working pressure. After each stage, intermediate coolers and water separators are provided. The compressed air then passed through the evaporation pre-cooler and then to the molecular sieve battery where the moisture and carbon di-oxide are removed from the process air. It then passes through the heat exchanger No.1 where it is cooled by the out-going waste nitrogen gas and product oxygen produced in the oxygen gas plants.A part of this cold air then flows through an expansion machine and the balance through the 2nd heat exchanger. The ratio of the two air streams is controlled by an expansion valve, RI. Both these streams of air then unite in the medium pressure column where it partially liquefies.
