PROCESS AND APPARATUS FOR PRODUCING OLEFINS FROM LIGHT ALKANES
First Claim
Patent Images
1. A method for producing olefins comprising:
- contacting a light alkane feed with dehydrogenation catalyst particles in each of reactors, wherein each of the reactors is a fluidized bed reactor partially embedded in a furnace;
converting at least a portion of the alkane feed to olefins using the catalyst particles, wherein the olefins form a part of a reactor effluent stream;
merging the reactor effluent streams from each of the reactors to form a first merged effluent stream; and
separating an olefin stream comprising the olefins from the first 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.
