A separate Acetone storage should be constructed and must be provided with a 12m safety zone all round.
- A distance of 90m. must be maintained from any Oxygen Plant in the vicinity.
- All non- flame and explosion proof switches must be provided separately in an enclosure away from the acetylene plant Building.
- No flammable material should be used for construction purposes of the Acetylene Plant Building.
- Both the Acetone go down and calcium Carbide Store as well as the Acetylene Plant Building.
Temperature Control:
The KANAK CRYO Acetylene Generator can be set to operate at given temperature, regardless of the size of carbide used or temperature of the cooling water, a sensitive sensor actuates a pneumatic control that adds water into the generator of the cooling water, A sensitive sensor actuates a pneumatic control that adds water into the generator tank when the temperature exceeds the set limit, thus maintaining a given standard temperature. This helps in complete utilization of carbide, which is a very expensive raw material.
High Pressure Control: If all the gas generated cannot be drawn in by the compressor and passed on the filling manifolds, either due to low capacity of the compressor or fast generation, gas pressure will gradually build in the generator. When the gas pressure reaches a predetermined level (about 0.5 kg/cm2) carbide charging will be cut off automatically and further generation of gas is stopped. There is no expensive gasholder with the Kanak Cryo Acetylene Generator. This Item alone will reduce the investment on such a plant. Furather, as the gas generated is always at a positive pressure, (once the plant has been purged will Nitrogen) no air can enter the system, and it is this feature which manes the Kanak Plant inherently ver safe.
Water Level Control: if excessive water enters the generator to cool it and the water level goes above the high level marks, the water level control instrument will immediately discharge the excessive water thus maintaining the level between the acceptable high and low level marks. Non Loss- Charge:- No gas is lost or wasted while charging the carbide because one section is completely sealed off from the generator by high pressure hydraulically operated valve. All the above controls are automatic and require no attention from the operator.
Condenser: The Acetylene gas leaving the generator is hot and carries with it some water vapour and other impurities. The condenser will cool the gas, thereby condensing the excessive moisture in preparation for its subsequent removal. The condenser is of amply proportion to suit local condition and ensures complete cooling, provided that sufficient water supply is maintained.
Low Pressure Drier:- The drier is charged with calcium chloride. This absorbs the moisture in the gas case a certain of moisture is necessary to enable the chemical purifier to function effectively, a by -pass is provided to allow part or whole of gas to be directly admitted into the chemical purifier.
Chemical Purifier: This consists of two layers of regenerative chemicals, which remove additional impurities. The purifying agent may be reactivated for re-use by the atmosphere air. For continuous operation one extra charge of chemicals can be kept in open wooden trolleys.
Water Scrubber: The equipment is installed between the chemical purifier and Acetylene Compressor which help to remove impurities from the gas if any. Acetylene Compressor: For filling of the cylinders an I.R. make reciprocating, oil lubricated, multistage, Water submerged compressor with intercoolers, safety relief valve for each stage, driven by a 15 H.P.
High Pressure Drier
This consists of a battery of three high - Pressure vessels. The first is filled with metal filler, which the second and third are filled which anhydrous calcium chloride. It is very important that the high pressure drier is fully filled up with Calcium Chloride, as any void in high - Pressure area against the required safety.
