Continuous catalytic regeneration (CCR) heaters

Sandvik electric CCR heaters are suitable for applications in the petrochemical industry, such as isomerization heater, reduction gas heater, and hot stripping heater. The electric heaters consist of tubular elements installed in a number of vessels connected in series. Read more about the continuous catalytic regeneration (CCR) process.

Construction materials

The elements and internals are constructed using alloy 800 and the vessel and tubesheet are in stainless steel of types ASTM 321H, 316Ti or alloy 800.

Temperature and capacity range

Sandvik CCR heaters have an operating temperature range of 10°–600°C (50°– 1112°F).

Available in capacities from 1–10000 kW, Sandvik electric process heaters have smaller footprints. They are virtually 100% efficient and there is no risk of fouling that creates a need for frequent cleaning.

There can be a number of reactors depending on process requirements. Some commonly known electric heaters for these reactors are:

  • Oxy-chlorination heater
  • Calcination heater
  • Burning step heater
  • Catalyst reduction heater
  • Catalyst hot H2 stripping heater
