A process and apparatus for cracking a hydrocarbon feed containing resid, comprising: heating a hydrocarbon feedstock containing resid; passing said heated hydrocarbon feedstock to a vapor/liquid separator; flashing said heated hydrocarbon feedstock in said vapor/liquid separator to form a vapor phase and a liquid phase containing said resid; passing at least a portion of said resid-containing liquid phase from said vapor/liquid separator to a thermal conversion reactor operating at 649° C. or more, wherein the thermal conversion reactor contains coke particles; and converting at least a portion of said resid into olefins.
