Fluid Catalytic Cracking FCC

AstraConcepts provides complete one point source Fluid Catalytic Cracking (FCC) Unit developed using in-house engineering expertise.  Services includes

  • Conceptual (FEL I), PDP (FEL II), DBM (Pre-FEED or FEL III)

  • FEED and Detailed Engineering Support

  • Commissioning and Start-Up Support

  • FAT, SAT and Training

  • Performance Guarantees

  • After Sales Service

AstraConcepts provides various FCCU configurations that meet customer expectations.  

AstraConcepts also supplies a standard FCCU scheme that meets key performance objectives:

  • FCC++®


FCC++® is a Fluid Catalytic Cracking Unit designed by AstraConcepts for maximum efficiency, recovery and productivity.  AstraConcepts utilizes state-of-art shell and tube heat exchangers designed to minimize fouling and enhanced energy recovery.  Remainder of heat is provided by the furnace, which is designed to minimize coking and maximize heat recovery through the convection section.  A CO/CO2 Boiler and Waste Heat Recovery Unit (WHRU) is used to generate steam for steam stripping, furnace steam and reactor atomization steam.  The tower is designed with conventional trays, allowing for increasing capacity through random and structured packing.  Special focus is provided to the wash section to de-superheat inlet gas, minimize entrainment and enhance recovery of Heavy Cycle Oil (HCO).  Tower temperature profile is maintained to maximize pump-around heat driving force and minimize localized corrosion.
