Abstract: Provided is a method for producing aromatic hydrocarbons from light alkanes. A light alkane is contacted with catalyst particles in each of reactors, wherein each of the reactors is a fluidized bed reactor arranged in parallel with each other in a furnace. At least a portion of the alkane feed is converted to aromatic hydrocarbons using the catalyst particles, wherein the aromatic hydrocarbons form a part of a reactor effluent stream. The reactor effluent streams from each of the reactors are merged to form a first merged effluent stream. Catalysts particles deactivated through the light alkane conversion are either regenerated inside the reactors or withdrawn from the reactors for regeneration outside the reactors. The furnace comprises multiple furnaces, and the first merged effluent stream from each of the furnaces is further merged with each other to form a second merged effluent stream.

Abstract: A process and an apparatus for producing olefins from light alkanes. A light alkane feed is contacted with catalyst particles in each of reactors, wherein each of the reactors is a fluidized bed reactor. At least a portion of the alkane feed is converted to olefins using the catalyst particles, wherein the olefins form a part of a reactor effluent stream. The reactor effluent streams from each of the reactors are merged to form a merged effluent stream. The merged effluent stream is separated into an olefin stream and the other streams. The other streams may comprise a recycle stream and light gases.
