What’s new in gas processing technology

H. Meche, Associate Editor Residue compressor aids NGL recovery The Atlas Copco TP Series residue gas compressor incorporates a three- to four-stage, dual-pinion integral gear design that delivers high flow levels and superior performance for NGL recovery plants. A single TP Series compressor unit can often replace multiple reciprocating compressors, and it can fully cover plants up to a rated flow of 120 MMscfd. Driven by an electric motor, it is a lower-emission alternative to engine- or turbine-driven compressors. The compressor’s integral gear technology operates two pinions through a common bull gear. This integral gearing allows for a more compact design and multi-speed capability
