Fluid Catalytic Cracking Units (FCC Cyclones) are the principal technologies that enable the critical process within heavy oil refining of converting the heavy oils into more valuable gasoline and lighter products. More than half of the refinery's heavy petroleum is processed through the FCC Cyclones, and the FCC Cyclones are also an important source of butene and pentene olefins used in refinery processes.
Our Emtrol-Buell brand has supplied more FCC Cyclones to refineries and petrochemical plants worldwide than any other supplier, so our experience in this area is unequaled. Our FCC Cyclones are designed to enhance separation efficiency, accommodate increased catalyst loading, and are tailored to meet the application needs of refineries and petrochemical plants.
We custom-engineer the following products at the highest quality:
In 1974, we introduced our exclusive Patented Beam Hanger Support System for use in FCC applications. It markedly reduces field costs and turnaround time, and our system has become the most successfully applied method for support of cyclones in "large diameter" FCC regenerators.
All regenerator internal cyclones systems must be supported in a manner that accommodates the differential thermal expansion that exists between the relatively cold vessel, which supports all vessel internals, and the cyclone system, which is exposed to a much greater temperature.
Our exclusive system utilizes an array of horizontally oriented beams, which extend from the plenum skirt toward the vessel head and from which both the first and second stage cyclones are supported. The ends of the beams supported by the plenum skirt are pinned to lugs fixed to the plenum skirt.
