Patent number: 9776103Abstract: A process and system for separating butenes and butanes by extractive distillation using a polar solvent is disclosed. The process may include: contacting a hydrocarbon mixture including butanes and butenes with a lean solvent mixture in an extractive distillation column to form an enriched solvent fraction comprising butenes; recovering an overheads fraction comprising butanes and a bottoms fraction from the extractive distillation column; feeding the bottoms fraction to a stripper including a stripping section and a wash section; recovering the lean solvent mixture as a bottoms fraction and a stripper overheads fraction comprising butenes and water from the stripper; condensing the overheads fraction to form a water fraction and a product butenes fraction; feeding water as reflux to a top of the stripper wash section; feeding at least a portion of the condensed water fraction intermediate the top and bottom of the stripper wash section as a second reflux.Type: GrantFiled: June 29, 2016Date of Patent: October 3, 2017Assignee: Lummus Technology Inc.Inventors: Kevin John Schwint, Robert J. Brummer

Patent number: 9744475Abstract: A process for recovering 1,3-butadiene from a C4 fraction, where the butadiene extraction processes may be operated at an intermediate pressure using a liquid ring type compressor. The use of a liquid ring compressor, among other process options presented herein, may advantageously reduce capital and operating costs, similar to the compressorless option, while mitigating the risks associated with the higher operating temperatures and pressures associated with the compressorless option. Thus, the embodiments of the processes disclosed herein encompass the best features of the conventional design (low pressure, with a compressor) with the advantages of the compressorless design (low capital and operating cost), as well as other advantages unique to the systems disclosed herein.Type: GrantFiled: March 3, 2016Date of Patent: August 29, 2017Assignee: Lummus Technology Inc.Inventors: Kevin John Schwint, Robert J. Brummer

Patent number: 7271307Abstract: The present development relates to a modification of the Houdry process for the dehydrogenation of aliphatic hydrocarbons, whereby the dehydrogenation cycle is extended, or lengthened, and hydrogen gas is added into the reaction. The combination of the extended cycle with the hydrogen introduction results in a surprising stabilization of the production rate in the dehydrogenation process. The hydrogen gas may be introduced through a recycle step. The process of the present development is demonstrated for the dehydrogenation of propane to propylene.Type: GrantFiled: October 28, 2003Date of Patent: September 18, 2007Assignee: Sud-Chemie Inc.Inventors: Michael A. Urbancic, Michael W. Balakos, Robert J. Gartside, Robert J. Brummer
