KBR announced that it has acquired isomerisation technologies from RRT Global that will enable KBR to offer expanded octane and clean fuel technology solutions to customers.

KBR, in alliance with RRT Global, has been offering MAX-ISOM catalytic distillation technology for the isomerisation of C5 and C6 n-paraffins to boost gasoline pool octane since 2015. Isomerisation of C5 and C6 streams is practiced to improve the octane rating of light straight run naphtha.

Now, KBR has acquired the patented technology with intellectual property rights to offer MAX-ISOM globally and to offer isomerisation technologies for C4 and C7 streams.

Isomerisation of C4 streams produces a more desirable feedstock for alkylation units such as KBR’s Solid Acid Alkylation Technology (K-SAAT). C7 isomerisation can be applied to upgrade low octane C7 streams to produce isomerate that can be blended directly in the gasoline pool.

Unlike conventional fixed-bed isomerisation process technologies, MAX-ISOM can accommodate high benzene content in the feed, due to its unique catalytic distillation column design. MAX-ISOM offers significant energy reduction, much smaller footprint and lower CapEx compared to traditional units.

“With the acquisition of these technologies, KBR now offers expanded octane solutions including isomerisation of C4, C5, C6 and C7 streams in refineries,” said John Derbyshire, president, KBR Technology Solutions.

MAX-ISOM is the technology of choice for the low-cost production of high octane isomerate, in a highly flexible and compact design with minimum energy requirements.

Globally, fuel specifications have been tightening on the sulphur, benzene, olefins and total aromatics content of gasoline. Isomerisation offers refiners a higher octane gasoline blend stock that is free from benzene, aromatics, oxygenates and olefins.
