NITROUS OXIDE PLANTS
Safe and economical, the Nitrous Oxide Plants from SANGHI OXYGEN is a plant with an efficient Generation system which reduces power consumption and adds on to safety. A storage battery assembly for separation of Nitrogen is another safety feature with the SANGHI OXYGEN plants. The gas manufactured conforms to Indian Pharmacopeia, US & European standards and is stored in liquid state which can be directly filled into cylinders.

Process Description
Nitrous Oxide is produced by heating Ammonium Nitrate to a temperature of 250 Deg.C. Ammonium Nitrate is decomposed in the process to give a mixture of Nitrous Oxide & super heated steam. At the same time impurities are produced including Ammonium Nitrate fumes, Nitrogen & other oxides of Nitrogen. The steam & impurities are removed by scrubbing with water, caustic soda and sulphuric acid in sequence Nitrogen present in traces is removed by bleeding from the top of storage vessels where Nitrous Oxide is stored, after compression by a compressor.

Production
It is produced by heating Ammonium Nitrate to a temperature of approximately 250 C. Heating could be either electrically or by gas. It is then purified in a series of towers before collecting in a gas holder.

Gas is then Compressed by a water lubricated compressor, dried and liquefied. Liquid Nitrous oxide is stored in storage vessels where Nitrogen, if present, is removed. Pure liquid Nitrogen oxide is then filled into cylinders by weight.

Uses
Nitrous oxide gas is mainly used for anesthetic purposes. It is administered with oxygen. It is also used as carrier gas in laboratory Instruments. It also finds application, as a propellant in aerosols and food stuff.

Properties of NITROUS OXIDE
Nitrous Oxide is a chemical compound of Nitrogen and Oxygen. Its Chemical symbol is N20.

It is colourless, non flammable and nontoxic gas with a slightly sweetish taste & odour. The most common way of distributing Nitrous oxide is as a compressed liquid in Cylinders of the same kind, as used for oxygen, Nitrogen etc. The pressure in Nitrous oxide cylinders is approximately 50 Bars at 20 Deg .C.

It is stable and comparatively un-reactive chemical compound at ordinary temperatures. At elevated temperatures, however, the gas decomposes to Nitrogen & Oxygen.

It supports combustion and hence organic substances particularly oil and greases which are petrochemical in nature must be kept away from the gas.

HYDRAULIC CYLINDER TESTING STATION
Gases like oxygen and nitrogen are filled in seamless steel cylinders at high pressure ranging from 150 to 200 bar. Such cylinders are also subjected to various weather conditions and handling during use at consumer's place as well as transport, loading and unloading.

Essentially, the cylinders are made of a material that has a flexibility of expansion and contraction during pressurization.

For various reasons this flexibility of expansion and contraction begins to deteriorate over a period of time. Similarly, on account of other conditions such as filling, handling, transportation and shop floor conditions, there are chances of weight reduction over a period of times. It may also develop certain other defects normally rendering a cylinder unsafe for use.

Globally such cylinders are required to be periodically tested for visual damages, weight loss of elasticity. In view of the dimension of damage, which can be caused by a bad cylinder, being known, most people prefer to test these high-pressure cylinders periodically.

We provide a complete set-up of equipment for conducting a dependable and assured hydraulic test for such cylinders.
