Abstract: In a broad aspect the present disclosure relates to a process plant and a process for upgrading a hydrocarbon mixture, withdrawn as a direct stream from a crude distillation unit and an initial boiling point below 200° C., and a fraction of at least 5% boiling above 500° C., 550° C. or 650° C. comprising the steps of a. directing said hydrocarbon mixture to a vacuum flasher unit, b. withdrawing a heavy hydrocarbon fraction from said vacuum flasher unit, c. withdrawing a light hydrocarbon mixture for hydrocrackingfrom said vacuum flasher unit, d. directing said light hydrocarbon mixture for hydrocracking and a stream rich in hydrogen to con-tact a material catalytically active in hydrocracking, e. withdrawing a hydrocracked stream of hydrocarbon from said hydrocracker. with the associated benefit of limiting the amount of asphaltenes, metals and other heavy components contacting said material catalytically active in hydrocracking.
