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.

Abstract: Disclosed are heaters having at least one adjustable fired burner and an adjustable fired burner for use with various types of heaters. The heaters may be part of an industrial processes such as petroleum refining. The adjustable burners are configured to be adjusted and positioned in any direction and then be locked into place. The adjustable burners may be adjusted automatically or manually. The ability to quickly adjust the position of an adjustable burner results in substantially less or virtually no damage to elements in the heater and provides for a more even distribution of heat within the heater.

Abstract: A multistage catalytic hydrocarbon conversion system is disclosed in which hydrocarbons flow serially through at least two reaction zones and through which catalyst particles move. Where three reaction zones are used, the effluent stream from the first reaction zone is split between the second and third reaction zones. One portion of the effluent stream is combined with hydrocarbons that bypassed the first reaction zone, and the combined stream is passed to the second reaction zone. The other portion of the first reaction zone effluent stream and at least a portion of the effluent stream of the second reaction zone are passed to the third reaction zone. This invention is applicable to processes where the first and second reaction zones are susceptible to pinning in that this invention decreases the mass flow through the first and second reaction zones while nevertheless maintaining high hydrocarbon conversion.

Abstract: A container for containing flowable material comprises a rigid tank having a top opening therein for filling the tank with flowable material. A bottom opening in the lowermost portion of the tank for evacuating the flowable material. A cap seals the top opening in the tank and a piping assembly is connected to the bottom opening. A collapsible bladder inside the tank prevents the flowable material from coming into contact with the tank. A mating top cover and bottom base assembly are shaped to receive and enclose the tank. The piping assembly includes a dispensing spout which utilizes a spout, a dry-lock or a spring valve.
