Abstract: A process for producing light alkanes and creating a flexible distribution system for those alkanes and related systems are disclosed. The process can include supplying a butane feed stream to a butane conversion unit to produce a light alkane output stream including at least methane, ethane, propane, and hydrogen, separating at least part of the light alkane output stream into separate streams of methane, ethane, and propane and distributing the separated streams as desired. The distribution of the separated streams can include sending the separated ethane and propane streams to downstream processing units which use them as feedstock. The butane containing feed and/or unreacted butane feed can include isobutane, which can be converted to n-butane and then further processed.

Abstract: A process is provided including subjecting a raw C5 stream containing C5 diolefins to extractive distillation to form C5 diolefins and a raffinate stream. The process includes subjecting the raffinate stream to dehydrogenation to form additional C5 diolefins, which are recycled to the extractive distillation. Another process includes modifying a C5 diolefin extractive distillation unit by forming a recycle loop with a C5 olefin dehydrogenation reactor. A system is provided that includes a C5 diolefin extractive distillation unit and a C5 olefin dehydrogenation reactor that are arranged in a recycle loop. A process is provided that includes subjecting a raffinate stream containing C5 olefins from an extractive distillation unit to dehydrogenation to form C5 diolefins.

Abstract: A process includes reacting a feed stream containing ethanol and optionally acetaldehyde in a dehydration reactor in the presence of a dehydration catalyst system having a Group 4 or Group 5 metal oxide and a support. The process includes obtaining a product stream containing butadiene from the dehydration reactor. Another process includes reacting a feed stream containing ethanol and optionally acetaldehyde in a dehydration reactor in the presence of a dehydration catalyst system containing a tungsten oxide supported on a zeolite or a tantalum oxide supported on a zeolite. The process includes obtaining a product stream containing butadiene from the dehydration reactor.
