QUOTATION FOR 150 CMH OXYGEN / NITROGEN PLANT
GENERAL PROCESS DESCRIPTION
The atmospheric air mainly consists of Oxygen and Nitrogen gases, together with small quantities of water vapour, carbon dioxide and other rare gases such as argon helium etc. Oxygen and Nitrogen from the air can be separated due to the difference in boiling points by distilling them through a fractionating column.
Free atmospheric air is sucked in by a multi stage compressor through a filter and compressed to the working pressure. The compressed air is then passed through a pre-cooling system, dust filters, moisture separators and then to the Molecular Sieve Battery for removing traces of carbon dioxide and moisture from the air. This purified air then passes through the first Heat Exchanger, where it is cooled by the out going Nitrogen and Oxygen. Part of this cooled air then passes through an expansion engine and the other part through the 2nd heat exchanger. Both the expansion engine and 2nd heat exchanger help in cooling down the air further, which is finally released to the bottom of the column through an expansion valve. The air becomes liquid at this stage.
The column is divided into two parts Lower column and Upper column. In between the lower and upper columns there is a condenser which acts as a reflux for the lower column and as a re-boiler for the upper column. The liquid air at the bottom of lower column separates through the trays of the column to give crude Oxygen at the bottom and 97% 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 poor liquid 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 Oxygen (which has a higher boiling point than Nitrogen) accumulates at the bottom of the upper column in the condenser.
Both Nitrogen and Oxygen are removed by separate pipelines through heat exchangers, for cooling the incoming air To the filling manifolds. Both Oxygen Nitrogen can be filled directly in to the cylinders through separate LOX and LIN pumps. Liquid Oxygen/Nitrogen can also be withdrawn in to the cryogenic tanks through the cryogenic pumps.

SALIENT FEATURES
1. THE PLANT IS CAPABLE OF PRODUCING OXYGEN AND NITROGEN SIMULTANEOUSLY.
2. The plant is equipped with a highly efficient expansion engine which lowers the operating pressure 40 kg/cm² resulting in a low power consumption of 1.0 unit of electricity per m3 of Gas produced and 90 Kg/cm2 for liquid will be 1.5 unit per m³. 3 The plant is equipped with separate Liquid Oxygen pump and separate Liquid Nitrogen Pump which will deliver dry Oxygen / Nitrogen directly compressed into cylinders. This pump does away with a bulky Oxygen / Nitrogen compressors required in other plants. 4. All spares and services are easily available with us and therefore we guarantee minimum down time for the plant. 5. The Oxygen produced from this plant can also be used for Medical purpose. 6. If a lesser purity gas is required it can be easily obtained by adjusting some parameters, resulting in 10 to 15% increase in capacity. 7. With the efforts of our R&D department we have been able to eliminate use of chilling unit from the Plant. This has helped in reducing the power consumption of the Plant as well as maintenance costs. We however offer the Chilling Plant as a standby to be operated only in very hot conditions. 8. We also recommend a single pump closed circuit water-cooling System to further reduce power consumption. 9. Our plant give you option of filling cylinders directly using the pumps or alternately filling the liquid oxygen & nitrogen in cryogenic storage tanks. Standard plants give only.. 10. We are giving insulation material for the pipelines and other equipments wherever required, whereas our competitors are not giving any insulation material.
