FCC Reactor & Regenerator Cyclones

Fluid Catalytic Cracking (FCC) is one of the most important refinery processes as it converts high-boiling, high-molecular weight hydrocarbon fractions of petroleum crude oils to more valuable gasoline, olefinic gases, and other products. Residue fluid catalytic cracking (RFCC) is used for upgrading heavy feedstocks to light products. Therefore, a properly designed and highly efficient FCC and RFCC cyclone system is extremely important to ensure refineries operate efficiently with reduced operating costs and remain competitive.

Ducon has an ongoing record of hundreds of successful operating FCC cyclone installations–since the 1970's–that operate reliably and maintenance free for years. Ducon secured numerous FCC Cyclone technology patents during the 1970's and 1980's. As an established supplier to the world's refineries, Ducon can ensure customer satisfaction through proven technologies, innovative engineering, expert manufacturing, and on time delivery. Available in several design configurations, Ducon FCC Cyclones, achieve over 99.9% catalyst collection efficiencies on particles down to 5 microns.

FCC Cyclones For Refineries

  • Ducon works with major licensors of FCC processes: UOP, EXXONMOBIL, TECHNIP, KBR, SHELL, CB&I, AXENS, FOSTER WHEELER AND OTHERS
  • Collection efficiency maximized: leading supplier of FCC catalyst recovery cyclones since 1970's
  • Reactor, Regenerator, Tertiary vessel and fourth stage cyclones
  • Supply of complete Reactor & Regenerator cyclones, Hanger systems,Tertiary Plenums, Diplegs and dipleg valves with plenums fabricated complete with internals
  • Ducon Dust hopper and lined dipleg designs enhance catalyst discharge while decreasing erosion
  • Reactor Cyclones configuration can be directly attached to the riser with a second stage following in a closed or open coupled system. In single stage configuration cyclones are preceded by a riser termination device.
  • Ducon provides performance evaluation & simulation of existing cyclones
  • High efficiency at low pressure drops with enhanced aspect ratio
  • Ducon Computer programs provide: Entrainment, catalyst loss, pressure drop & optimal cyclone geometry
