Clean Fuels

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. We offer solutions for clean fuels production, including low sulfur gasoline and diesel, to meet increasingly stringent environmental standards.

Using proven catalytic distillation processes, the combination of the CDHydro® hydrogenation and CDHDS®/CDHDS+® hydrodesulfurization processes is a low capital cost and operating cost solution. The process effectively reduces the sulfur level of full-range FCC naphtha, while retaining most of the octane value without yield loss. Sulfur content is reduced by more than 99%.

Technological advances in hydrocracking and deep hydrotreating produce clean Euro-V/VI quality diesel from straight-run, fluid catalytic cracking (FCC), residue hydroconversion or delayed coking-derived gas oils.

The ISOCRACKING® technology, offered by Chevron Lummus Global, a joint venture between CB&I and Chevron U.S.A. Inc., produces high-quality jet and diesel fuels and heavy naphtha suited for catalytic reforming. The ISOCRACKING process is often used in conjunction with residue hydrocracking—employing the LC-FINING™, LCMAX® and LC-SLURRY technologies—or with delayed coking.

Diesel can also be produced by fluid catalytic cracking. CB&I’s FCC and Resid FCC (RFCC) processes have long been trusted workhorses to meet the demand for motor fuels. These licensed technologies are continuously improved to meet today’s refinery challenges, including:

  • Cracking a wide range of feedstocks (heavy vacuum gas oils to residues)
  • Increasing operational flexibility
  • Shifting the yield slates from maximum gasoline to maximum diesel and vice-versa

Gasoline Production

The FCC unit continues to provide a major portion of the gasoline pool. CB&I is uniquely positioned to offer FCC technology that is unmatched in performance, robustness and flexibility.

Diesel Production

The ISOCRACKING® technology, offered by Chevron Lummus Global (CLG), a joint venture between CB&I and Chevron U.S.A. Inc., produces high quality jet and diesel fuels and heavy naphtha suited for catalytic reforming.

Selective Gasoline Desulfurization and Tier 3 Solutions

CB&I's CDHydro®/CDHDS+® technology has been well-proven in the refining industry to reduce sulfur levels in FCC gasoline while maximizing octane retention. 

Gasoline Alkylate Production

The CB&I CDAlky® gasoline alkylation technology is an advanced sulfuric acid alkylation process that operates at significantly lower temperatures than conventional technology. The CB&I AlkyClean® gasoline alkylation technology employs a true solid alkylation catalyst. 

Ethers

CB&I offers an array of commercially well-proven, patented etherification technologies for the production of high-quality ethers.

Residue Desulfurization

Residue desulfurization is a high-pressure catalytic hydrotreating process. Chevron Lummus Global (CLG), a joint venture between CB&I and Chevron U.S.A., Inc., offers several proven technologies for residuum desulfurization.
