Atlas Copco has announced that it has supplied a compressed air supply system for a project that is converting domestic and industrial waste into energy.

The project is being commissioned at Dargavel, Dumfries in Scotland.

Part of the plant’s advanced thermal treatment process employs compressed air supplied from an Atlas Copco Compressors system.

The facility was designed, built and privately funded by Ascot Environmental.

Operated by Scotgen, the plant uses hazardous and non-hazardous waste to provide an essential resource for power and heat production while managing residual wastes usually destined for burial without capture of any energy content.

The plant is able to process waste from domestic, agricultural and industrial sources and will generate 6.2MW of electrical power per year for the National Grid.

It is planned that the heat produced from the gasification process will be used by local industries.

Atlas Copco was originally contacted for its proposals for a compressed air supply by process engineering consultant Otto Simon , which was assisting Ascot Environmental with the project.

The Dargavel installation now comprises two network-linked GA37+ 8 bar, full-feature, oil-injected rotary screw compressors with integrated air treatment and downstream filtration, together with an OSC600 oil/water condensate separator, an EWD 330 electronic condensate drain, a 3,000 litre air receiver, plus an ES4i integrated sequence controller.

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

Here, pulses of air are required periodically to clean the filtration bags housed in three units on site.

Air is also supplied to the continuous emission monitoring system to ensure that all emissions to atmosphere are cleaned of contaminants to a level that satisfies environmental requirements.
