Jacobs Engineering Group was selected to provide technical services for Braskem on portions of the recently-acquired Marcus Hook refinery near Philadelphia, the companies said on Tuesday.
Officials did not disclose the contract value.
Jacobs' operations in Mt. Laurel, N.J. and Conshohocken, Pa. are expected to execute the work, the company said.
Braskem acquired propylene splitter assets at the 781-acre refinery complex in late June.
Jacobs' initial scope of work includes retrofitting the new acquisitions so Braskem can more efficiently process propylene for use in its adjacent polypropylene plant.
Since this past December, Pennsylvania officials have tried to identify potential uses for the refinery, said Jacobs vice president Bob Pragada.
Braskem's acquisition and capital investment is hopefully the first step in re-purposing the complex as a multi-purpose energy processing facility."
