Abstract: Methods and systems for heating a reactor feed in a multi reactor hydrocarbon dehydrogenation process. The methods and systems are advantageously employed for the production of styrene by the catalytic dehydrogenation of ethylbenzene. The catalytic dehydrogenation process employs heating steam operating at a steam to oil ratio of about 1.0 or less and relatively low steam superheater furnace temperature, such that all components exposed to steam in the process (outside of the fired heaters) can be constructed with standard metallurgy.

Abstract: A gas phase catalytic reactor comprising a metal vessel defining a confinement volume in which electromagnetic waves are generated at a frequency greater than 10 MHz. The confinement volume contains a porous catalyst which is heated by the electromagnetic waves and which has a flow of reactive gas passing therethrough. In order to guarantee that the gas reacts only when in contact with the catalyst, a heat exchanger is used to cool the gas suddenly as it leaves the confinement volume.

Abstract: Apparatus and method to improve flow of fluid through an annular bed in a radial flow treatment vessel. An elongated annular baffle is disposed in the reactor adjacent the bed to impart generally U-shaped flow to the fluid either prior to entering or after it exits the bed thus achieving an overall serpentine or reverse U-shaped flow pattern as the fluid proceeds from an entry port to an exit port in the reactor. Means are provided in the baffle to permit minor amounts of fluid to bypass the generally U-shaped flow path in order to correct fluid flow maldistribution through the bed that is attributed to frictional pressure drop in the flow channels adjacent to the bed. A vessel according to the invention can be operated with fluid flow through the vessel in either direction.

Abstract: The invention concerns a process and an apparatus for performing chemical reactions under pressure in the presence of a solid catalyst in a multi-stage reaction zone, after external intermediary thermal conditioning. This process may be used for the synthesis of ammonia or methanol or for gasoline reforming. It is characterized in that at least one reaction fluid is introduced into at least one compartment, a first reaction effluent is recovered, a heat exchange takes place, outside the reaction zone, between a first effluent and an external heat exchange medium, then said first effluent is introduced into at least one subsequent compartment and a second reaction effluent is recovered from said subsequent compartment. The reaction fluid or reaction effluent circulates cross-wise in the compartments substantially perpendicularly to the reaction zone, the compartments being tight and of elongate shape, each compartment being adjacent to one or two other compartments, each group of two adjacent compartments comprising a common partition, wall, either substantially parallel to said generatrix or substantially oblique with respect thereto.

Abstract: An improved reactor is disclosed wherein a high temperature product gas discharged from a catalyst bed within the reactor is cooled in a central heat exchanger installed within the reactor by heat exchange with a low temperature feed gas comprising gaseous raw materials for the reaction, and the product gas is thereafter flowed along the inner surface of an outer pressure vessel in order to maintain the outer pressure vessel at a low temperature. Inlet and outlet pipes for a coolant which coolant is circulated through a coolant passage structure which penetrates the catalyst bed in order to absorb the heat of reaction, both penetrate the top cover of the outer pressure vessel so that the coolant passage structure can be readily removed for maintenance and inspection, and the overall design of the reactor is simplified.

Abstract: Method and apparatus for effecting a multiple stage contact to a reactant stream such as a multistage dehydrogenation of ethylbenzene to styrene. The reaction feed stream is passed alternately in outward and inward radial flow directions through a plurality of adjacent annular reaction zones and withdrawn from intermediate reaction zones and channeled to mixing zones longitudinally adjacent the next successive annular reaction zones. A heat exchange medium is introduced into such mixing zones in a manner effecting both a downstream flow thereof to the next reaction zone and mixing with the reactant stream.
