A process for cracking a heavy hydrocarbon feed comprising a vaporization step, a coking step, a hydroprocessing step, and a steam cracking step is disclosed. The heavy hydrocarbon feed is passed to a first zone of a vaporization unit to separate a first vapor stream and a first liquid stream. The first liquid stream is passed to a second zone of the vaporization unit and contacted intimately with a counter-current steam produce a second vapor stream and a second liquid stream. The first vapor stream and the second vapor stream are cracked in the radiant section of the steam cracker to produce a cracked effluent. The second liquid stream is distilled in a fractionator to produce an overhead stream, a side draw, and a bottoms stream. The side draw is reacted with hydrogen in the presence of a catalyst to produce a hydroprocessed product. The hydroprocessed product is separated into a gas product and a liquid product. The liquid product is fed to the vaporization unit. The bottoms stream is thermally cracked in a coking drum to produce a coker effluent and coke. The coker effluent is passed to the fractionator.
