The global oil and gas industry has experienced a large push for higher production capacity. At the same time, government and regulatory restrictions across many nations mandate that industrial installations reduce their carbon footprint. In a typical petrochemical complex, compressors for oil, gas and refrigeration are the major consumers of energy. Historically, many compressors have been driven by gas turbines and engines. However, in recent years, electric motor ratings in the multimegawatt range have become common and economically competitive with turbines. As a result, some end users are selecting electric motors and adjustable-speed drives (ASDs) as compressor prime movers.
