Abstract
A hydrocarbon conversion process is described. The process includes passing a hydrocarbon stream through a plurality of reaction zones and a plurality of fired heaters, the effluent from a first reaction zone passing through one of the plurality of fired heaters before entering a second reaction zone. The plurality of fired heaters include a radiant section, an inlet manifold, an outlet manifold, at least one heater tube having an inlet and an outlet, the inlet being in fluid communication with the inlet manifold and the outlet being in fluid communication with the outlet manifold, and at least one burner, the inlet manifold of one of the plurality of fired heaters being at a vertical height different from a vertical height of at least one of the other inlet manifolds or at least one of the outlet manifolds.

A hydrocarbon conversion process comprising:
- passing a hydrocarbon stream through a plurality of reaction zones and a plurality of fired heaters, an effluent from a first reaction zone passing through one of the plurality of fired heaters before entering a second reaction zone, the plurality of fired heaters being in side-by-side configuration and each comprising:
- a radiant section, an inlet manifold, an outlet manifold, at least one heater tube having an inlet and an outlet, the inlet being in fluid communication with the inlet manifold and the outlet being in fluid communication with the outlet manifold, and at least one burner, the inlet manifold of one of the plurality of fired heaters being at a vertical height different from a vertical height of at least one of the other inlet manifolds or at least one of the outlet manifolds, wherein the inlet manifold and outlet manifold are within the radiant section, and wherein the vertical height is relative to a common reference point.
A catalytic reforming process comprising:
- passing a hydrocarbon stream through a plurality of catalytic reforming reaction zones and a plurality of fired heaters, an effluent from a first reaction zone passing through one of the plurality of fired heaters before entering a second reaction zone, the plurality of fired heaters being in side-by-side configuration and each comprising:
- a radiant section, an inlet manifold, an outlet manifold, at least one heater tube having an inlet and an outlet, the inlet being in fluid communication with the inlet manifold and the outlet being in fluid communication with the outlet manifold, and at least one burner, the inlet manifold of one of the plurality of fired heaters being at a vertical height different from a vertical height of at least one of the other inlet manifolds or at least one of the outlet manifolds, wherein the inlet manifold and outlet manifold are within the radiant section, and wherein the vertical height is relative to a common reference point.
