HDPV2 Gate Handling Calcium Carbide

Client:
Acetylene gas manufacturer/supplier
Product Quantity:
Size:
Application:
Discharge batches of dry calcium carbide from one pressurized holding vessel into another. The batch is then fed into a reactor, where it is mixed with water to produce acetylene gas.

Material:

Calcium carbide and acetylene gas react with one another to create oxyacetylene gas. Especially in the fabrication industry, oxyacetylene gas is used to fuel a very high temperature flame, which allows them to weld and cut metal.

Results:

Previously, the client used a ball valve in this process. It became a source of frustration, as calcium carbide would build up inside the ball valve – to the point that the valve was difficult to actuate. Two operators and a breaker bar were required to manually open and close the ball valve. This process was time-consuming and a safety hazard.

The replacement to the ball valve would require:

  • The ability to close on dry solid materials.
  • Sealing gas in a pressurized system (12 psi | 0.8 bar)

In most valve designs, closing on dry solid materials would cause seal wear – to the point that the acetylene gas could no longer be contained.

The Vortex HDPV2 Gate is specifically designed for use in pressurized conveying systems. Its sealed body and O-ring sealing design prevents leakage of air and materials across the gate and to atmosphere.
