Oil & Gas

CCI DRAG Valve technology has advanced along with the Oil & Gas industry. Quick stroking requirements for compressor recycle have reached one second or less using low cost, highly reliable pneumatic actuation. This is a major trademark advantage of CCI Control Valves.

Oil & gas production and transportation

CCI’s Valve Doctors® have spent years developing technology that meets the demands of today’s oil & gas Industry. The challenges of higher wellhead pressures, with aggressive fluids and entrained solids, have been met with the combination of advanced materials and DRAG® velocity control technology.

Severe service applications are critical for:

  • eliminating unwanted noise
  • protecting major equipment components
  • minimising loss of product or feedstock
  • increasing compressor efficiency

Eliminating unwanted noise

High fluid velocities through the pressure letdown process will create aerodynamic noise. Controlling the fluid velocities through the letdown path to an acceptable level will ensure that noise is not created in the first place. This is called source treatment – noise is not merely hidden; it's not created in the first place. CCI DRAG® technology takes the entire pressure drop through the disk stack and attenuates the noise to the specified level without the use of downstream devices or silencers.

Protecting major equipment components

The compressor is one of the most expensive pieces of equipment for an oil & gas Plant. A compressor can go into surge if the flow drops below 80% of the rated flow. The CCI DRAG valve is designed to respond and open within 1 second – to protect the compressor from surge flow. A good control system along with the CCI DRAG valve will provide a long life for the compressor.

Minimising loss of product or feedstock

If a gas-to-flare valve is leaking, then precious product is going to flare where it will be wasted. Repeatable, tight shutoff is essential to ensure that the product or feedstock will go where it should be going – i.e. to the customer – and not be burned.

Increasing compressor efficiency

Compressor recycle valves need repeatable tight shutoff to optimise the efficiency of the compressor. Most of the cost of a compressor is the cost of the energy to run it over a period of time. This cost is much greater than the cost of the valve. When a valve is leaking, the compressor requires more energy to meet the same throughput. This leaking inefficiency can far outweigh the costs of the valve over time, even the cost of the compressor.
