Universal Boschi is a leading manufacturer and exporter of air separation plants such as oxygen plants, nitrogen plants and acetylene plants. With the association of ING. L. & A. Boschi of Italy, our company fabricated plants that perform in compliance with the plants of international standard. We started manufacturing of nitrogen & oxygen production plant at our factory in New Delhi (India) in 1985 and air separation columns in Genova, Italy.

 

 

The designs of our plants are based on the process cycle of Linde & Claude which had been started by Dr. Boschi of Italy with its company ING. L. & A. Boschi of Italy in 1930. We acquire Boschi technology and design as Boschi technology is proven worldwide for a number of features such as contact design, low power consumption, low maintenance and highly pure output. With the years of experience and technical collaboration with Dr. Boschi, our company has fabricated over 300 air separation plants and equipments.     

What is CE Mark?

Apart from ISO 9001:2000 certification, Universal Boschi products are also CE approved. Basically, the CE mark is a quality-mark. First, it refers to the safety & quality of a product. Second, most quality markings are voluntary opposite to the CE marking, which is mandatory for the products supplies to European Market. CE indicates conformity with mandatory European safety requirements. European conformity is certified by following clear and understandable procedures, the so-called ‘conformity assessment procedures’. 

 

We have got success in manufacturing and exporting low pressure plants as it is the technology of today.   


Safety Measures Taken
Oil grease or similar substances must not be allowed to come into contact with compressed oxygen or liquid oxygen. Contact of this substance with oxygen may result in an explosion. Personnel working in an area of possible oxygen concentration, such as near an oxygen vent or a liquid oxygen spillage, or in a trench where oxygen seepage and concentration might occur, must ensure that their clothing is free from contaminations of oxygen before lighting a cigarette or approaching a naked flames. It is essential that the clothes be dries for at least 15 minutes before approaching a flame after any such contamination.

The following precautions must be strictly observed Oxygen Gas Plant, Nitrogen Gas Plant, Acetylene Gas Plant at all times:
1: Thoroughly wash all oxygen fittings, valves and parts with clean Tricolor Ethylene / carbon tetra chloride (CTC) before installation. Never use petrol, kerosene or other hydrocarbon solvents for this purpose. All tubing, lines valves etc. to be used in oxygen service, must be of an approved type and must be thoroughly degreased and blown out with clean oil-free compressed air or Nitrogen before being placed in service.

2: Do not permit the release of Acetylene or other flammable gases in the vicinity of the plant air intake. A concentration of Acetylene exceeding 5 parts per million in liquid oxygen may explode with extreme violence. Strict supervision is essential to minimize the possibility of contamination.

3: The plant and the plant vicinity must be kept clean and free from abstractions at all times. Any oil leak within the plant surrounding must be rectified without delay. Oil spillage must be cleaned up immediately using rag and carbon Tetra Chloride.

4: Do not lubricate oxygen valves, regulators, gauges or fitting with oil or any other substance.

5: Ensure that insulation removed from the Air Separator jacket is not contaminated with oil or other inflammable materials. Personnel carrying out maintenance on the Air Separation Plant equipment must wear clean overalls and their hands and tools must be free of oil. This ensures that the insulation and equipment within the jacket is not contaminated with oil. Should contamination take place the affected materials must be discarded and replaced by clean new material?

6: Do not fasten electric conduits to the plant or its pipelines.

7: Do not use oxygen as a substitute for compressed air, spark present in an atmosphere of oxygen will immediately burst into flame.

8: Do not fill any container or pipe line with oxygen unless it has been thoroughly degreased with clean CTC or TCE.

9: When discharging liquid oxygen or rich liquid from drains, valves or pipe lines, open valves slowly to avoid the possibility of being splashed. In particular ensure that liquid does not run into shoes or gloves. Contact with liquid oxygen rich liquid will cause frostbite evidenced by whiteness and numbness of the skin. The affected parts must be batched at once in cold (not box) water and seek medical attention immediately.

10: . Do not breathe cold oxygen vapor. The temperature of the vapor rising from liquid oxygen is approximately - 181 Deg C. A deep breath of vapor at this temperature can result in frost-bitten lungs with resultant serious illness and permanent
disability or death.

11: Do not experiment with liquid oxygen by putting solids or liquids into it for the
purpose of watching the effect of the cold liquid. The object placed in the oxygen may catch fire or explode.
Safety Measures Taken contnd
12: Do not pour liquid oxygen on the floor of the shop or around any object that can catch fire. As the liquid oxygen vaporizes, the cold vapors may be swept along ground into contact _ith combustible material. The whole floor of an office is known to have caught fire when oxygen vapors contacted a lighted cigarette butt. Spillage of liquid oxygen must be avoided especially in the vicinity of lubricated machinery, asphalt paving, concrete surface containing bitumen joints or where the liquid oxygen can flow into drains or sewers.
13: Do not use any pipe jointing on oxygen pipe threads except approved for oxygen service. Ordinary pipe jointing contains grease as a lubricant and will catch fire.

14: Compressor and Expander lubricating oil consumption must be regularly checked any excessive consumption must be investigated immediately and the cause rectified.

15: occur or if liquid level is unaccountably lost in the plant, and if any check indicates oxygen concentration above 21%, immediate action should be taken to locate and rectify.

16: The use of a flame ( e.g. for welding or cutting) in the immediate vicinity of the Air Separation Plant or oxygen piping must be permitted only when the plant has been shut down and de frosted and when the oxygen content of the air within the equipment concerned does not exceed the atmospheric normal of 21%. Do not attempt repair until all pressure is released from the section to be dismantled.

17: Remember that pressure alone is not dangerous. A Boiler at 0.7 Kg/cm2g may be more destructive in the event of an explosion than a small container at 220 kegs/cm2 owing to the greater mass of metal involved. In general, fluid at high pressure and moving at a high velocity are the most dangerous. Use a face shield or chemical type safety goggles when using the oxygen or nitrogen test set to prevent possible injury to the operator in the event of a blow-back of the reagent.
