摘要：
An integrated process to convert crude oil into petrochemical products by subjecting the crude oil to crude oil distillation to produce gases fraction, naphtha, kerosene, gasoil and resid; subjecting resid to resid upgrading to produce LPG, light-distillate and middle-distillate; subjecting at least a portion of one or more of the group consisting of middle-distillate produced by resid upgrading, kerosene and gasoil to middle-distillate hydrocracking to produce LPG, light-distillate and hydrowax; and subjecting at least a portion of one or more of the group consisting of light-distillate produced by resid upgrading, light-distillate produced by middle-distillate hydrocracking and hydrowax to steam cracking. A process installation for performing the process of the present invention is also provided, and together allow conversion of crude oil into petrochemical products having an improved carbon-efficiency, while maintaining a high ethylene yield and a favourable ethylene:propylene ratio.
