The ThruPlus delayed coking technology is a proprietary process for upgrading heavy oil into high value, light hydrocarbon liquids.

Bechtel’s oil, gas and chemicals unit president Jack Futcher said the purchase of the ThruPlus technology is a natural progression and it allows the company to deliver customers high-quality, technologically superior coking units more efficiently and cost effectively.

The technology expands Bechtel’s capabilities in refining industry and achieves higher unit throughput, higher service factors, superior liquid yields and improved unit reliability.

Bechtel and ConocoPhillips formed an alliance in the 1990s that combined Bechtel’s expertise in engineering, cost optimization, procurement, and construction with ConocoPhillips’ operating experience and technology expertise in delayed coking.
