Abstract
One exemplary embodiment of the present invention can be a fired heater for a hydrocarbon conversion process. The fired heater includes inlet and outlet headers or manifolds, a set of heater tubes with each heater tube having an inlet and an outlet, at least one restriction orifice adjacent the inlet of at least one heater tube. The restriction orifice may be within the inlet manifold and adjacent the inlet of a heater tube, or between the inlet manifold and the inlet to the heater tube. A process may include passing a hydrocarbon stream through the fired heater described herein during the course of operating a hydrocarbon conversion process.
Claims12
A hydrocarbon conversion process comprising passing a hydrocarbon stream through at least one fired heater comprising a radiant section, an inlet manifold, an outlet manifold, at least one heater tube having an inlet and an outlet wherein the inlet is in fluid communication with the inlet manifold, at least one restriction orifice located within the inlet manifold adjacent the inlet of a heater tube or between the inlet manifold and the inlet of a heater tube, and at least one burner before passing the stream to at least one reaction zone wherein the at least one fired heater further comprises a plurality of interheaters, wherein each interheater comprises at least one burner, a radiant section, a manifold, at least one heater tube having an inlet and an outlet wherein the inlet is in fluid communication with the inlet manifold, at least one restriction orifice located within the inlet manifold or adjacent the inlet of a heater tube or between the inlet manifold and the inlet of a heater tube, and the process further comprising passing an effluent from a first reaction zone to a first interheater wherein the effluent from the first reaction zone passes through the first interheater before exiting the first interheater to enter a second reaction zone.
A reforming process comprising operating the reforming unit including a plurality of heaters, wherein each heater comprises at least one burner, a radiant section, an inlet manifold, an outlet manifold, at least one heater tube having an inlet and an outlet wherein the inlet is in fluid communication with the inlet manifold, at least one restriction orifice located within the inlet manifold and adjacent the inlet of a heater tube or between the inlet manifold and the inlet of a heater tube;
- and wherein the reforming unit comprises a first, a second, a third, and a fourth reaction zone.
