Fluid Catalytic Cracking Cyclones

We have incorporated many new features into our cyclones to enhance the separation efficiency, accommodate increased catalyst loading and to minimize wear on internal surfaces of the cyclone equipment.

Some of the new design features focus on the aspect ratio of the cyclone inlet, limitations on flux rates and cyclone inlet to outlet criteria.  Other features are related to the construction details, where we have adopted a new crossover duct design and have minimized the use of edge bars in the refractory linings throughout the cyclone assembly.  We have also developed a dust hopper and lined dipleg stub design that enhances the catalyst discharge from the cyclones and mitigates the effects of erosion.

We can evaluate your existing cyclone system for current operating rates and recommend necessary modifications to help maximize the performance and/or minimize potential erosion problems that could result in unscheduled shutdowns.  If you are interested in obtaining a recommendation and quotation, please visit our general list of items required to recommend cyclones for use in FCC service for pertinent information.

Emtrol has supplied equipment for all the major refiners and their respective affiliates, including BPAmoco, Caltex, ChevronTexaco, ExxonMobil, Phillips (including Tosco) and TotalFina Elf.

Clearly, the repetitive selection of Emtrol cyclone systems by these refiners has been inspired by the excellent results attained by the systems we previously provided to them and their affiliates.

Furthermore, we are approved by all the FCC process licensing companies as a qualified supplier of cyclone equipment, namely:
