Process Description Of Sanghi Acetylene Generator

The SANGHI Acetylene Generator is of an advanced design, incorporating several features not ordinarily found in other generators. The SANGHI Acetylene generator is a fully automatic plant. Pneumatically controlled valves and highly sensitive sensors, integral with the temperature control instruments, perform all operations. These in turn open the water inlet valve or residue drain valve etc. Two hydraulic pumps help to open and close the supply of calcium carbide, which is fed into the generator by screw feed conveyors. The screw feed mechanism and the agitators are operated by flameproof motors and fittings. The entire operation is perfectly synchronized to give maximum efficiency and simplicity in operation. Any failure, whether it is of power supply, water or air is signaled visually and also audibly when an alarm bell rings to alert the operator.

Only flame-proof lights & electrical fittings according to IS 214868 (group II) or BSS- 229 may be used in an acetylene plant building. Acetylene cylinder must be of specification IS: 7312:1974 or ICC: 8.

No Loss - Carbide charge

No gas is lost or wasted while charging the carbide because that section is completely sealed off from the generator by a high-pressure hydraulically operated valve. All the above controls are automatic and require no attention from the operator. There a further safety device, in terms of an alarm bell, which will ring continuously till the fault is corrected.

Instrument Air Compressor

A flameproof motor with a buffer tank drives the instrument air compressor.

Sanghi Purifying Mass & L K Mixture

A mixture of purifying mass & LK Mixture is used to remove impurities such as Sulphur, Phosphorus, Arsenic, Ammonia etc. in the form of hydrides such as Hydrogen sulphide, Phosphine etc. This chemical is regenerative, can be used for several applications.

Sanghi-Weighing Scale:

Dial Scale 3205 CLE/COE Capacities: -100, 200, 300, 500 & 1000 Kg. White pointer with a black indicator to give shadowless line-to-line (non-parallax) indication on 584 mm dia. Ready line. Scale mounted on four wheels enclosed in a substantial cast iron frame. Tough, dustproof, and moisture-proof housing to stand up to any conditions. This ensures no rusting and no deterioration of the mechanical components.

Introduction

Safe and economical, the Nitrous Oxide plant from SANGHI OXYGEN is a plant with an efficient Generation system that reduces power consumption and adds to safety. A storage battery assembly for the separation of Nitrogen is another safety feature with the SANGHI OXY plant. The gas manufactured conforms to Indian Pharmacopia, US & European standards and is stored in a 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 & superheated 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 Nitrous 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 a 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 N,0. It is a colorless, nonflammable, and nontoxic gas with a slightly sweetish taste & odor. 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°C It is a 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 old and greases which are petrochemical in nature must be kept away from the gas.
