Our Company has patronized the technology of Boschi,Italy as it has been the most successful in the world specially in Europe due to excellent design features and efficient process cycle. The boschi process and technology is highly RELIABLE with PROVEN performance of over 70 years. The process of manufacture of oxygen and nitrogen from oxygen/nitrogen plants has been very much simplified by Dr.Boschi of Italy with the following advantages.
|
Oxygen and nitrogen is made from atmospheric air. |
|
The process of manufacture involves deep refrigeration/cooling of atmospheric air involving cryogenic temperatures. |
|
Oxygen and Nitrogen is made from the purest form that is liquid air which is separated by process of rectification/distillation. |
|
The oxygen and nitrogen can be drawn in liquid form or converted into gas up to 155/200 bar by a built in liquid oxygen/nitrogen pump. |
|
Oxygen purity upto 99.7%for industrial and medical grade is produced. Nitrogen gas can be collected at 0.1bar at the outlet of the cold box and compressed as per requirement or can be pumped upto 150/200 bar by method of internal compression by a liquid nitrogen pump. The standard commercial purity of nitrogen gas is 96-99% and upto 99.99% or ppm grade can be produced. |
|
There is no requirement of raw materials and no recurring cost of Chemicals in the BOSCHI process. |
|
The oxygen and nitrogen plants are designed for continuous duty and are automatic and can be operated by just one person. |
We have commenced the manufacture of the oxygen/nitrogen plants at New Delhi in 1985 under expert supervision of the Italian Engineers with the ultimate goal to manufacture the same quality of plants produced in Europe with a much cheaper labor cost.
We have been highly successful in exporting back to Italy to Ing L & A Boschi, Italy equipments and oxygen plants for sale in Europe and other parts of the world.
Dr.Boschi himself took the trial and successful run of the first oxygen and nitrogen plant manufactured at New Delhi in 1986 and certified ok for export to Italy and meeting international standards.
Now it has been over 23 years since we have been manufacturing oxygen and nitrogen plants at New Delhi with the technology of Ing L. & A. Boschi, Italy as per the designs and drawings. We have skilled and trained technicians at our factory who have been manufacturing air separation plant, oxygen plant, nitrogen plant, liquid nitrogen /oxygen plants and equipment since 1985 under supervision of qualified engineers to meet inter-national specification. Our Company is engaged as manufacturers and suppliers of air separation plant and gas plants in India. We are producing the air separation plants, oxygen plant, nitrogen plant and acetylene plants of latest technology of ING &A BOSCHI,ITA Y who have been the world leader in setting up oxygen/nitrogen/acetylene plants, machine, factory and related machinery since 1930 in Italy along with LINDE Germany. Our oxygen plants factory have been exported to all countries including South Africa, Tanzania, Kenya, Congo, Liberia, Columbia, Congo, Jordan, Libya, UAE, Saudi Arabia, Iraq, Iran, Europe, Italy, Spain, Australia.
Detailed Manufaturing Process
 |
The free saturated air is sucked from atmosphere through a highly efficient dry-
type suction filter into the first stage of the horizontally balanced
opposed, reciprocating air compressor.
 |
This consists of purification of the air by removing moisture, oil traces and carbondioxide in the process air. Compressed air is chilled to 12 °C in a chilling unit and evaporation cooler, compressed air passes through the oils of the hilling unit at a temperature of 12 °C to a moisture separator, where the condensed moisture gets removed before entering into Molecular Sieve Battery. Before sending the air to MOLECULAR SIEVE BATTERY, air is passed through an OIL ABSORBER where air becomes oil free. Chilled air passes through the Molecular Sieve Battery consisting of Twin Tower packed with molecular sieves to remove moisture and carbon dioxide present in the air.
Molecular Sieve Battery operates on Twin Tower System, when one tower is under production the other tower is regenerated by passing waste nitrogen gas at 200 °C through a REACTIVATION HEATER .After interval of 8 to 10 hours, the tower under production gets exhausted and regenerated by similar process before use and, thus the cycle continues. Any dust particle gets filtered in the DUST FI TER before air enters the AIR SEPARATION COLUMN All the equipments are mounted on process skid.(See our Catalog)
Chilled, Oil-free and moisture-free air enters into multi-pass HEAT
EXCHANGER No.1 where it gets cooled to (-80)deg C by cold
gained from outgoing waste nitrogen and oxygen. A part of air,
this enters a multi-pass HEAT EXCHANGER NO.II or liquifier
made of special alloy tubes. This air cools to (-170)degC before
passing through an expansion valve. Due to Joule Thompson Effect
after the expansion valve, air gets further cooled down and gets
liquefied before entering into Bottom Column .
