Some of the best known names in the industry rely on CB&I to design and build their downstream oil and gas processing facilities, as well as provide cost-effective licensed technologies and catalysts. We offer a comprehensive range of technology and engineering, procurement, fabrication and construction services for the downstream oil & gas industry, with a focus on: 

  • Refinery process units
  • Petrochemical facilities
  • Gasification plants
  • Hydrogen generating plants
  • Sulfur processing plants
  • Bulk liquid storage structures for both atmospheric and low temperature/cryogenic storage
  • Licensed technologies and related catalysts for refining, petrochemical and gas processing
  • Heat transfer equipment 

Within these focus areas, CB&I can provide any combination of front-end design, engineering, procurement, fabrication, construction, project management and commissioning services across all phases of the project life cycle.

CB&I has considerable expertise in many state-of-the-art refining and petrochemical technologies, including gasoline blending components, bottom-of-the-barrel processing, olefins, polypropylene, styrene/polystyrene, light hydrocarbons (C3-C5), phenolics and other specialty chemicals. CB&I has the unique ability to offer our clients a full-scope product utilizing both in-house technologies and proven EPFC services.

Flexible commercial model

From a commercial standpoint, CB&I offers a balanced and flexible contractual approach to each project based on the needs and preferences of the client and with the objective of balancing risk between contractor and client. While we continue to execute projects on a lump sum basis where it makes sense, we are contracting more and more projects on a "hybrid" basis, where a defined scope of work may be performed lump sum and the balance on a cost-reimbursable basis, which allows for risk sharing between the two parties. We also work on a purely cost-reimbursable basis as appropriate.


CB&I provides a fully-integrated package of advanced process technologies and a complete spectrum of engineering, procurement, fabrication and construction services for the refining industry.
