The PetroChina Dushanzi Petrochemical Tarim 1.2 million tons/year Phase II Ethylene Project achieved successful first-feed commissioning, marking the official commissioning of China's first ethylene plant with fully electric-driven compressors using indigenous technology. Shanghai Nancal Electric Co., Ltd. overcame multiple technical bottlenecks and successfully developed ultra-large capacity, high-reliability medium voltage drives for the million-ton-class ethylene plant. This solution can be applied to both new million-ton-class ethylene projects and retrofit upgrades of existing units.
Nancal Electric has officially launched its comprehensive, one-stop retrofit and upgrade service for medium voltage drives. Power cells and control systems can be easily renewed, delivering a major reliability upgrade, with both on-site and factory remanufacturing options. Our solutions help extend equipment service life and improve operational efficiency.
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.
