Polished Continuous Catalytic Regeneration (Ccr) Heater

Continuous Catalytic Regeneration (CCR) is a critical process in petroleum and petrochemical industries, where aromatics are produced from naphthenic and paraffinic feedstocks. During the CCR process, hydro-treated naphtha is heated to 495–535°C (923–977°F) and mixed with recycled hydrogen gas.
As the reactions are endothermic, multiple electric process heaters are required at different stages to maintain temperature and ensure optimal conversion.

FITZER are engineered to deliver precise temperature control, maximum efficiency, and long service life — meeting stringent licensor requirements such as UOP, Axens, and others.
