Specification of Isomerization Process Heaters
The isomerization process upgrades the octane number of light naphtha fractions and also simultaneously
reduces benzene content by saturation of the benzene fraction. Isomerization complements catalytic reforming
process (CCR) in upgrading the octane number of refinery naphtha streams.
The heater designs generally governed by licensor specifications such as UOP, axens or by international
specifications.
