JUST^® Refinery (JGC Unitized Smart Tailored Refinery) is a stand-alone refinery concept which, by employing new technologies, enables a 30% reduction of CAPEX over conventional refineries with similar functions, thereby improving the IRR by 5%. Whereas conventional refineries need multiple hydrogen desulfurization systems for each fraction (naphtha, kerosene, gas oil), the JUST^® Refinery has integrated the hydrogen desulfurization systems into a single system for the combined stream.

Flow Scheme (Conventional vs Just Refinery)

In this process, crude oil is first fractionated into gas oil and lighter fractions and a residue. The gas oil and lighter fractions are hydrotreated all at once in one Hydrotreater to meet the sulfur specification of each product. After hydrogen desulfurization, the gas oil and lighter fractions are further fractionated into LPG, light naphtha, heavy naphtha, kerosene, and gas oil. The heavy naphtha fraction is processed through a catalytic reforming unit to produce a reformate for gasoline blending. Hydrogen produced at the catalytic reformer is used for Hydrotreater(HTR), therefore, JUST^® Refinery has a system of hydrogen self-sufficient . Moreover, the integrated utility facility and a simplified offsite facility also contribute to reducing the total refinery CAPEX and OPEX.
Sulfur in product gas oil specified in Basic Design Package is less than 50 ppm. Furthermore, pilot test results have shown that sulfur in product gas oil could be less than 10ppm.
