ConocoPhillips Coker and Refinery Expansion (CORE)

Roxana, IL

Answering the Call for Help.

PayneCrest earned an AGC Keystone Award for its work on the ConocoPhillips (now the Wood River Refinery) Coker and Refinery Expansion (CORE). The project demonstrated PayneCrest’s abilities to effectively drive momentum on an extremely complex project by proficiently delivering an ever-expanding scope of work. PayneCrest was initially engaged on a limited scale, but its reliability earned it additional assignments to help the construction team catch up on milestones and deliver the highest quality possible. Its work encompassed the coker plant and associated systems, several large substations, the new coke handling system, the Sulfur Recovery Unit (SRU), and several auxiliary systems, including a large heat trace project that encompassed the entire Wood River Refinery site.
