Breath of fresh air for waste conversion


A ground-breaking project to convert domestic and industrial waste into energy is being commissioned at Dargavel in Scotland. Part of the plant's advanced thermal treatment employs compressed air from an Atlas Copco system.

The site will offer a commercially viable non-landfill alternative for 60,000t of waste a year and will generate 6.2MW of electrical power a year for the National Grid.

The Dargavel 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, an EWD 330 electronic condensate drain, a 3,000l air receiver, plus an ES4i integrated sequence controller.

The compressed air system supplies all of the plant and instrument air with its main application in flue gas filtration. Pulses of air periodically clean the filtration bags housed in three units on site. Air is also supplied to a continuous emission monitoring system to ensure that all emissions are cleaned of contaminants to satisfy environmental requirements.
