Decant Oil (DC O) is heavy oil recovered from the bottom of a Fluid Catalytic Cracking (FCC) Unit at QP Refinery in Mesaieed.
As the end of the processing chain, DCO is high in density and in sulphur content, but low in viscosity (less than 100 cSt). DCO is used as a blending material for utility/bunker fuels or in production of “carbon black”.
