Air for energy project

A project to convert domestic and industrial waste into energy at Dargavel in Scotland uses compressed air from an Atlas Copco Compressors' system.

The advanced thermal treatment facility, designed and built by Ascot Environmental, is operated by ScotGen. It will offer a commercially viable non-landfill alternative for 60,000t of waste per annum.

The plant will process waste from domestic, agricultural and industrial sources and will generate 6.2MW of electrical power per year for the National Grid. Heat from the gasification process will be used by local industries.

The installation comprises two network-linked GA37+ 8bar, full-feature, oil-injected rotary screw compressors with integrated air treatment and downstream filtration, an OSC600 oil/water condensate separator, EWD 330 electronic condensate drain, 3000L air receiver, and ES4i integrated sequence controller.

The system supplies all plant and instrument air, with its main application being in the flue gas filtration facility.
