Hengli Petrochemical (Dalian) Refinery Co. Ltd., a subsidiary of Hengli Group, Wujiang, Jiangsu Province, China, has let a contract to Rotork PLC, Bath, UK, to supply electric and pneumatic valve actuators and valve gearboxes for flow control at its integrated 20 million-tonne/year crude-to-paraxylene refining and petrochemical project in Hengli Petrochemical Industrial Park (HPIP) on Changxing Island in Dalian, Liaoning Province, China (OGJ Online, July 12, 2017; Mar. 8, 2016).
As part of the contract, Rotork will supply about 2,000 of its proprietary IQ nonintrusive, intelligent multiturn, explosion-proof electric actuators with double-sealed IP68 water-tight protection to ensure reliable operation of gate valves and ball valves in the refinery’s tank farms, which are in a saline-ambient environment, the service company said.
The IQ actuators—dataloggers of which are equipped to record detailed operating data including valve torque profiles, the number of valve operations, and alarms for download and analysis—are combined with Rotork Gears IB multiturn and IW quarter-turn secondary gearboxes to meet operating demands of the wide range of valve sizes and types, and the pneumatic actuators orders encompass Rotork CP, GP, and RC ranges of scotch-yoke designs for quarter-turn valves to facilitate direct-drive actuation of valves of virtually any size, according to Rotork.
Rotork disclosed neither a value of the contract nor a timeframe for when it will complete the order.
Hengli most recently let a contract to Honeywell UOP LLC to provide its proprietary Callidus advanced flares and low-nitrogen oxides (NOx) burner technology to help reduce NOx emissions at the Dalian integrated complex to half the limit prescribed under China’s new emission-control regulation, Honeywell UOP said in a Nov. 16, 2017, release.
As of November, the Dalian complex had more than 25 processes in operation, according to Honeywell UOP.
