Acetylene Gas Plants

DISSOLVED ACETYLENE GAS PLANT:

Oxyplants India Pvt Ltd is a leading Manufacturer & Exporter of Dissolved Acetylene Gas Plants. Dissolved Acetylene Gas Plants Manufactured by Oxyplants is of an Advanced Technology Design. Incorporating several features not ordinarily found in other generators and made as per international ASME standards. The Dissolved acetylene gas plant is fully automatic with twin hoppers and all the operations are performed automatically by pneumatically controlled valves assisted along with highly accurate sensors and integral with the temperature control instruments and needs an operator's attention for only ten minutes in an hour.

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. This is fed into the generator by screw feed conveyors. The screw feed mechanism and the agitators are operated by flame-proof 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, instruments air, is signaled visually and also audibly when an alarm bell rings to alert the operator.

Only flame proof lights and electrical fittings according to IS21481-68 (Group II) or BSS-229 may be used in an acetylene plant building. Acetylene cylinders must be of specification IS: 7312: 1974 or ICC: 8. 

The design of the entire plant has been made with safety in mind. Flash back arrestors, high pressure reverse flow check valves, auto vent valves, non-return valves and flash back arrestors are also provided to make this plant absolutely safe to operate in all conditions.

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.

Process Description:

Oxyplants Dissolved Acetylene Generator is 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 gas produced in the generator is at 0.5 – 1.4 Kgs/Cm²g  and passed through coolers, driers, purifiers to achieve purity and compressed in a Multi stage water immersed compressor. The compressed acetylene gas is filled into the cylinder in the filling manifold at 15 Kg/Cm²g   and cooled by water spraying to achieve better absorption of gas in the acetone of the cylinders.
