The Fluid Catalytic Cracking (FCC) and Resid FCC (RFCC) processes have long been trusted workhorses in the refining industry to meet the demand for motor fuels. The FCC/RFCC processes utilize a powdered catalyst that continuously circulates between a short contact time reaction zone (riser) and a higher temperature regeneration zone where coke deposits are removed by burning in presence of air. CB&I’s FCC/RFCC licensed technologies are continuously improved to meet today’s refinery challenges, including:
CB&I’s FCC/RFCC processes employ Micro-Jet Plus™ feed injectors for intimate contact of feed with the hot regenerated catalyst, enhancing catalytic cracking as well as minimizing unwanted thermal cracking reactions. ModGrid® stripper internals achieve high efficiency hydrocarbon removal from the spent catalyst.
The patented Reaction Termination Device, incorporating proprietary direct-coupled cyclones, rapidly and efficiently separates the catalyst from vapors at the end of the riser. In addition, our FCC technology utilizes a patented Multi-Stage Orifice (MSO™) combustion air distributor design and proprietary spent catalyst distributor for superior regenerator performance. These are commercially proven and cost-effective technology features that result in substantial performance and reliability improvements. They can be easily implemented during planned turnaround schedules.
CB&I can help refiners identify the areas of maximum benefit and implement the identified changes on a fast-track basis with a single-source integrated approach. This includes basic engineering, detailed engineering and procurement, all the way through to construction and startup.
