Yokogawa selected by Chevron Phillips Chemical for USGC Petrochemicals Project

15-Nov-13

Yokogawa Electric Corp. has been selected as the main automation contractor for Chevron Phillips Chemical Company LP’s USGC Petrochemicals Project. The project, first announced in March 2011, will include an ethane cracker with capacity to produce 1.5 mln tpa and two new polyethylene facilities, each with an annual capacity of 500,000 tons. The ethane cracker will be built at Chevron Phillips Chemical’s Cedar Bayou plant in Baytown, Texas, and two polyethylene units will be built at a site in Old Ocean, also in Texas and near Chevron Phillips Chemical’s Sweeny plant. As the Main Automation Contractor for the project, Yokogawa will supply the control systems, safety systems, remote instrument enclosures, and the analyzer shelters and analytical systems. The control system platform will be based on Yokogawa's highly reliable CENTUM® VP integrated production control system. While CENTUM VP is classified as a distributed control system (DCS), it goes beyond a traditional DCS by offering a more intuitive human machine interface and a large-capacity field control station to process data faster while maintaining exceedingly high reliability. The dual-redundant configuration of processor cards combined with pairing each processor card with two CPUs (pair & spare configuration) ensures uninterrupted operations and high availability.
