Brief Process Description :-
‘Oxyplant’ Acetylene Generator is a Stationary Carbide to water Automatic Generator. Acetylene is generated as a result of the chemical reaction between Calcium – Carbide and Water. The by-product is Calcium-Hydroxide (Lime Slurry) which is continuously discharged from the generator. The Acetylene produced in the Generator is at 0.5 kgs/cm2 and passed through coolers, Driers, Purifiers to achieve purity and compressed in a three stage water Cooled Compressor. The Compressed Acetylene gas is filled into the cylinder in the filling Manifold at 15 bars and cooled by water spraying to achieve better absorption of gas in the Acetone of the cylinder.

The Gas produced is highly flammable and explosive, if mixed with air. Therefore various safety devices and automatic systems are incorporated to avert fire and/or explosion. These systems make the Acetylene Plant is highly sophisticated and safe equipment.

ACETYLENE Plant having the following Machineries and Equipments:

The ‘Oxyplants’ Acetylene Generator is Horizontal cylindrical steel vessel with dish ends having agitator and its drive unit, Carbide hoppers, Screw feeders and its drive units, Flash back arresters, Safety valves, Drain systems and the allied automatic Control systems.

The Generator tank is filled with water to high level and Carbide is made drop in the water through the screw feeder system. When the Carbide drops inside the Generator tank the Acetylene gas is generated due to the Chemical reaction and passes through the Flash back arrester to the other system in the plant.

6. Acetylene Compressor

This is 3 Stage Compressor driven by Flame Proof Motor and lubricated by flash and forced lubrication system. The compressor along with interstage coils and purge vessels are immersed in a water filled tank to avoid in any pressurized acetylene to come in contact with air and also to make sure that all the components are continuously cooled. The third stage pressure is determined by the setting of backpressure regulating valve.

7. High Pressure Drier

The high pressure drier consists of three columns .The first column is filled with Mild steel Chain packings to avoid any void and proper mixing. The Second and Third Columns are fitted with two capsules each and are filled with Anhydrous Calcium Chloride. Each column is fitted with drain valves to drain the moisture colleted at the bottom periodically.

8. Filling Manifolds

The Acetylene gas-filling manifold consists of two headers, each having provision for filling 30 cylinders at a time. Each header is individually fitted with Non-return valves; Flash back arresters, Pressure gauges and Manually Isolating Valves.
