  • Process development by parallel operation of paraffin isomerization unit with reformer
    Patent number: 8808534
    Abstract: A process for refining naphtha that results in an improved octane value in a subsequent gasoline blend. Certain embodiments include separating a naphtha feed into light naphtha and heavy naphtha; separating the heavy naphtha into a paraffin stream and non-paraffin stream; introducing the light naphtha to a first isomerization unit, introducing the paraffin stream to a second isomerization unit; introducing the non-paraffin stream to a reforming unit and combining the resulting effluents to form a gasoline blend. The resulting gasoline blend has improved characteristics over gasoline blends that are made without introducing the paraffin stream to a second isomerization unit.
