Abstract
Official abstract text for this publication.
Embodiments of processes for producing propylene from paraffins are provided. The process comprises the steps of combining an effluent that comprises propylene and propane from a paraffin dehydrogenation reactor with an offgas stream that comprises propane to form a combined effluent stream. The combined effluent stream is separated into a propylene product stream and a propane-rich recycle stream. The propane-rich recycle stream is introduced to the paraffin dehydrogenation reactor operating at dehydrogenation conditions to convert propane in the propane-rich recycle stream to propylene.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for producing propylene from paraffins, the process comprising the steps of: combining an effluent comprising propylene and propane from a paraffin dehydrogenation reactor with an offgas stream from a butane isomerization process comprising propane and hydrogen to form a combined effluent stream; passing the combined effluent stream through a chloride treater and dryer unit to generate a treated combined effluent stream; separating the hydrogen…
