Barrel compressors

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 pressure ratios and the lower flow rates experienced in these 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, manufactured, installed and supported by Rolls-Royce.

Standard configurations are available up to 4500 psig (310 bar) maximum working pressures and up to 35,500 acfm (60,300 m³/h) flows.

Power ratings range from 35,000 to 75,000 hp (26,100  to 56,000 kW) at design speeds from 3,500 to 13,800 rpm.
