Abstract: Contemplated plants thermally integrate operation of a refinery component, and most preferably of a hydrocarbon splitter with LNG regasification to provide refrigeration duty and with a power cycle to provide the reboiler duty of the component. It should be noted that such configurations advantageously allow operation of the splitter at a reduced temperature and at reduced pressure, thereby increasing separation efficiency, while the power output is boosted using air intake chilling. Most notably, such process advantages are achieved by satisfying the heating duty of LNG regasification.
