Sanghi Overseas

Worli, Mumbai, Maharashtra

The SANGHI-ORG Nitrogen Plant, is safe and economical to operate. It comes with an efficient expansion engine, which lowers the operating pressures remarkably to as low as 32-35 kg/cm2 and also cuts down power consumption.

A Molecular sieve Battery drier unit for separation of moisture and carbon dioxide is another money-saving device in the SANGHI-ORG plant. It removes acetylene and other hydro-carbons from the process air, thus eliminating the need for separate acetylene absorbers, and moreover it eliminates recurring caustic soda costs.

The SANGHI-ORG Nitrogen Plant is capable of simultaneously producing high purity nitrogen Gas. It also has internal compression Liquid nitrogen Pump to fill dry gaseous oxygen in cylinders.We also undertake supervision of Installation and Commissioning of the SANGHI-ORG Nitrogen Plant.

About 100 CU.M./Hr of Nitrogen will be used for regeneration of driers for SANGHI-ORG 80.

* About 150 CU.M./Hr of Nitrogen will be used for regeneration of driers for SANGHI-ORG 100.* About 300 CU.M./Hr of Nitrogen will be used for regeneration of driers for SANGHI-ORG 200.The above product capacities are based on ambient conditions of 15oC temperature 760mm of Hg pressure and 50% relative humidity and 0.03% of Carbon Di-oxide is allowed as impurity.

Plant Specifications1. Production Capacity - The plant is very versatile and can be set for a cycle to produce any one of the following alternatives:-

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.

Introduction

Safe and economical, the Nitrous Oxide plant from SANGHI ORGANIZATION 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 ORG plant. The gas manufactured conforms to Indian Pharmacopia, US & European standards and is stored in liquid state which can be directly filled into cylinders.

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 Nitogen 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 20oC

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.
