Uzbekistan: Kizilkumcement has upgraded its grinding separation process with five ZH15000-5-7 compressor units manufactured by Atlas Copco. Each of the new three-stage centrifugal air compressors has a capacity of 250m3. Energy saving aspects of the project include reducing the installed capacity of the compressor from 1600kW to 1400kW; electricity savings due to automatic capacity control, and accordingly the compressor power consumption when changing the compressed air flow rate at the output; and reduction of pressure loss in the pipeline by reducing the length of the duct by decentralising the compressor station and installing new compressors near the consumer of compressed air.
