    Full Process Integration Challenges

    Features

    Combines slurry hydrocracking and Hydroprocessing in one hydrogen gas loop

    Requires both sour and sweet fractionation systems products fractionated twice

    Slurry HC and Hydroprocessing sections require same high reactor pressure

    Challenges

    Moderate effect on overall capital and operating costs

    H2 S and NH3 depress catalytic activity and selectivity

    Selective Integration Benefits

    UOP offers many integration options to meet refiners varied requirements

    Examples Common H2 recovery and compression systems for make-up gas

    and off-gas Parallel recycle gas systems Uniflex products integrated directly to UOP Unicracking and UOP

    Distillate Unionfining

    Benefits >10% capital savings for Uniflex, Unicracking, Distillate

    Unionfining Heavy Oils Complex Performance optimized of each unit

    Reduced contamination in catalytic process units Unicracking: >99% VGO conversion Distillate Unionfining - Maximum diesel yield, quality and cycle length
