Abstract
An integrated process for production of gasoline has been described. The process includes a C-Cisomerization zone with an associated deisohexanizer, two Cisomerization zones separated by a deisoheptanizer, and a reforming zone. The use of two Cisomerization zones eliminates the need for the large recycle stream from the deisoheptanizer. The Ccycloalkanes and heavies from the deisohexanizer are fed to the second Cisomerization zone to increase the amount of 95 RONC gasoline produced. A higher percentage of 95 RONC gasoline may be achieved by further recycling Cfrom deisoheptanizer overhead back to C-Cisomerization zone. Higher gasoline yields and higher percentage of 95 RONC gasoline is achieved over the whole naphtha complex with operating costs savings by fully integrating the C-Cisomerization zone, two Cisomerization zones, deisohexanizer and deisoheptanizer columns.
