Sandvik electric isomerization heaters are used in ethylene production plants in the petrochemical industry. Ethylene reacts with halogens to produce halogenated hydrocarbons. Sandvik electric heaters can be used to regenerate the catalyst used in this process. Typical heater applications are catalyst reduction, catalyst hot H2 stripping, catalyst oxidation, reactivation and reactivation-burning. Sandvik has genuine expertise in designing electric heaters and control systems for such hazardous applications. Read more about ethylene production by steam cracking.
Materials of construction
Sandvik isomerization heaters consist of tubular elements installed in baffle cage assemblies with tie rods holding the assembly together.
The elements and internals are constructed of alloy 800, and the vessel and tube-sheet are of stainless steel of the types ASTM 321H, 316Ti or alloy 800.
Temperature and capacity range
Sandvik isomerization heaters have an operating temperature range of 0°–600°C (32°– 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.
