A hydrocracking unit takes vacuum gas oil, and cracks the heavy molecules into middle-distillate products (diesel fuel, jet fuel and kerosene), naphtha and LPG, in the presence of hydrogen and a catalyst. Hydrocracking is an extremely versatile and flexible process that offers the refiner to process various feeds, and operate under diverse process conditions by utilizing different types of catalysts to produce different product slates. Reactor design and number of processing stages play a role in this flexibility. Ruwais Refinery East (RRE) of Abu Dhabi National Oil Company (ADNOC) has single stage once-through hydrocracker unit that used as lube oil plant feed as well as low sulfur oil blends diesel fuel.
