Acetylene plant: Advance Acetylene Production
Acetylene plants are used in various industries for the production of acetylene gas. The plants are designed to obtain the highest carbide yield and efficiency. Plants are compliant with international standards. Each component is carefully engineered to meet the customer’s requirements.
The acetylene plant is constructed and inspected with a best practice policy that meets the intent of design principles and manufacturing practices from Section VIII of the ASME codes. It is also designed for NFPA 51A: “Standards for Acetylene Charging Plants ”.
Components of acetylene plants
The Generator has temperature safety instrument, water inlet control, high water shutoff, low water level alarm, automatic carbide feeding, automatic residue discharge, and over pressurization safety relief valves. A Double hopper automatically feeds the carbide in the generator.
- Temperature Control
- High-Pressure Control
- Water Level Control
- No Loss-Carbide Control
Acetylene Cooler Condenser
The acetylene gas passes through a cooler condenser. That lower the temperature with help of cross flow cooling water.
Low Pressure Drier
The acetylene gas then passes through a low-pressure drier. To remove water that get trapped during carbide reaction.
The gas passes through a purifier to remove impurities. The purifier assists in removing impurities.
The ammonia scrubber removes 99% of the ammonia. Thus preventing formation and clogging of flame arresters and cylinders.
A 3 stage compressor increases the acetylene pressure. Cooling coils and condensate traps are located at each stage. Coils and traps are submerged in water to cool the acetylene gas.
High Pressure Driers
The high pressure driers remove moisture and oil. The gas then flows through a special filter, flame arrester, and a back pressure valve. Then is directed to the manifold. Where every station valve is protected with a flame arrester. A flame arrester, reverse flow check valves, and handwheel connections are on the end of the pigtail at the cylinder.
Precautions when making the Acetylene Plant building (As per PESO guidelines):
A safety zone of 15 m. all around the Acetylene Plant from other buildings should be provided. And a minimum of 9 m. from any slurry pit.
A separate acetone godown should be constructed that must have 9 m. all around.
A distance of 90 m. must be maintained from any Oxygen Plant.
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 the construction of the Acetylene Plant building.
Both the acetone godown and calcium carbide store as well as the Acetylene Plant building should be well ventilated with ventilators on the roof as well as ground level. All ventilators must be protected with noncorrosive, galvanized mesh, with a minimum gauge of 11 mesh to the linear cm. Covers should be provided on the ventilators so that rainwater may not enter through these openings.
All electrical wiring should be of low voltage in the Acetylene Plant premises. Electrical lines must not cross or run in the same trench used for conveying water or steam or acetylene.
