Hydrocracking is an established and reliable method for transforming low-value heavy oil fractions into products with a higher value. In today’s market, refinery operators face a range of new technical, regulatory and commercial challenges: ensuring that their operations meet environmental standards; complying with new fuel specifications; and upgrading their refinery’s ability to meet capacity and quality targets.
Shell Global Solutions’ dual-service hydrocracking process technology combines advanced process know-how with high-performance catalyst systems and efficient reactor internal designs. This combination provides high levels of availability that deliver consistently high yields of quality products in an energy-efficient manner: all essential in enabling refinery performance to be optimized cost-effectively.
Mild Hydrocracking
With the mild hydrocracking heavy gas oil fractions are partially converted to produce lubricant base oils, catalytic cracker or ethylene cracker feedstocks, and high-quality distillates for automotive fuels.
For each new application, we match the optimum configuration with the given feedstock and the required processing objectives. Additional product slate flexibility can be achieved through the choice of catalyst system or by adjusting the process conditions.
We offer a hydrocracker product work-up section that features a single main fractionator. This innovative configuration provides a 35-40% reduction in fractionation furnace energy consumption when compared with the conventional stripper-fractionator configuration.
