A 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 thermally cracked in a coking drum to produce a coker effluent and coke. The coker effluent is separated into a coker gas and a coker liquid. The coker liquid 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.

Process for cracking heavy hydrocarbon feed

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.

A method for reducing coke fouling in a burner tip when a waste gas stream containing unsaturated hydrocarbons is combusted by coating the interior of the burner tip and/or impregnating the body of the burner tip with a hydrocarbon hydrogenation promoting catalyst and/or a combustion catalyst.

Method for reducing coke fouling in a burner tip

A method for thermally cracking a hydrocarbonaceous feed material using a combustion fuel fired furnace wherein at least part of the combustion fuel employed in the furnace is syngas.

Thermal cracking

A remote staged furnace burner configuration includes placement of secondary fuel gas nozzles remote from burners. This configuration brings about an increased mixing of secondary fuel with furnace fuel gases. As a result, the temperature of the burning fuel gas is lowered and NOformation is reduced.

Remote staged furnace burner configurations and methods

A remote staged radiant wall furnace burner configuration includes placement of secondary fuel gas nozzles remote from radiant wall burners. This configuration brings about an increased mixing of secondary fuel with furnace flue gases. As a result, the temperature of the burning fuel gas is lowered and NOformation is reduced.

Remote staged radiant wall furnace burner configurations and methods

A method and apparatus for continuing the operation of a fuel fired furnace when the air supply from the blower to the furnace is interrupted by employing a combination of a ventilator and drop door, the ventilator having a power source independent of the blower.
