1. A process for steam cracking a whole crude or a portion thereof to produce olefins and/or aromatics, the process comprising:
contacting a whole crude with steam to volatilize a portion of the whole crude, wherein the contacting of the whole crude and steam forms hydrocarbon droplets having a D10 of greater than about 30 microns;
recovering a vapor phase comprising volatilized hydrocarbons and steam and a liquid phase comprising unvaporized hydrocarbons;
feeding the vapor phase to a steam pyrolysis reactor to convert at least a portion of the hydrocarbons therein to olefins and/or aromatics.
