A well-known domestic chemical enterprise planned to implement an energy-saving, emission-reduction, and capacity-expansion project for its polycarbonate production unit. This included converting the originally steam-driven MVR steam compressor to electric drive. The MVR steam compressor system was originally driven by a high-speed steam turbine (referred to as the steam turbine), directly connected to the drive shaft of the high-speed centrifugal compressor. The NC HVVF series medium voltage drives provided by Nancal Electric delivered excellent high-frequency drive performance and system safety control performance for the high-speed PMSM in this MVR steam compressor "steam-to-electric" retrofit project of a polycarbonate production unit, providing highly reliable and sustainable technical support for the project retrofit.
