Continuous Catalytic Regeneration (CCR) is a Part of the process used in the production of petroleum and petrochemicals. The CCR process produces aromatics from naphthenic and paraffin, after being heated to reaction temperature 495 – 535°C (923 – 977°F), hydro-treated naphtha is merged with recycled hydrogen gas.
There are several applications in a CCR process that require the use of electric process heaters. Because the chemical reactions are endothermic (i.e. absorb heat), multiple heaters are required at various stages in order to increase the fluid temperature at the proper level and to achieve successful chemical reactions. The heater designs generally governed by licensor specifications such as UOP, axens etc.
