The purpose of this unit is to improve the octane number to produce higher octane gasoline.
The light naphtha produced in the distillation unit after filtration at the hydrogen
purification unit of this unit is sent to the isomerization unit, and with linear linear
paraffins being branched, the octane number is increased from an approximate value
of 65 to 87. The unit is capable of producing 1093 cubic meters per day of isomorph gasoline.
