Available in four standard frame sizes, our multi-stage barrel compressors provide the oil and gas industry with natural gas gathering, re-injection, lift, depletion, storage/withdrawal and re-pressurisation solutions.
Barrel compressors are the preferred choice for high heads of pressure and low flow rates experienced in these applications.

Rolls-Royce uses advanced techniques to analyse each compression project to select the most flexible and efficient frame and rotor combination. For optimum performance predictability and production economy, each barrel frame size is based on families of standard stage components.

Capabilities
Standard configurations are available up to 6500 psig (450 bar) maximum working pressures and up to 22,000 acfm (37,400 m³/h) flows. Power ratings range from 4,000 to 45,000 hp (3,000 to 37,300 kW) at design speeds from 5,000 to 13,600 rpm.

Applications
Rolls-Royce barrel centrifugal compressors are found in a variety of natural gas compression applications. Installations range from single units to multiple-unit trains, driven by gas turbines or electric motors. Complete systems for onshore or offshore are designed, manufactures, installed and supported by
Rolls-Royce.
