(ASX: WOR)

WorleyParsons awarded refinery EPCM and fabrication contract by Chevron

WorleyParsons has been selected to provide engineering, procurement, construction management and fabrication services for Chevron’s Salt Lake Refinery Retrofit Project in Salt Lake City, Utah. The EPCM contract (valued at approximately USD67M) is for the retrofit of an existing Hydrofluoric Acid (HF) alkylation process unit at Chevron’s refinery in Salt Lake City, Utah and the replacement of HF in the plant with ISOALKY, a proprietary alkylation technology developed by Chevron USA Inc., which uses ionic liquids catalyst technology.

Under the agreement, WorleyParsons will modularize the new facilities to minimize construction in the vicinity of the operating refinery units and provide significant overall cost savings. WorleyParsonsCord will also play a key role in the project by fabricating the modules in Edmonton, Canada. The WorleyParsonsCord contract value is projected at approximately USD20M.

This new plant will be the first of its kind using the new liquid catalyst technology on a commercial scale which is expected to significantly lower risks and environmental impact.

“Chevron’s selection of WorleyParsons and WorleyParsonsCord for the implementation of new refining technology is an example of our company’s diverse capabilities and support of our long standing relationship with Chevron,” said Andrew Wood, Chief Executive Officer of WorleyParsons.
