Abstract: An improved isomerization process in which the inlet temperature to the isomerization reaction zone is less than 105° C. is described. A separate reactor is provided for the decomposition of the organic chloride. The product of the decomposition of the organic chloride is sent to an isomerization reactor along with a hydrocarbon feed containing paraffins. The use of the organic chloride decomposition reactor allows the operating temperatures for the isomerization reaction zone to be reduced.

Abstract: One exemplary embodiment can be a process for isomerizing a feed stream including one or more C4-C6 hydrocarbons. The process may include contacting the feed stream in an isomerization reaction zone with an isomerization catalyst at isomerization conditions to produce an isomerization zone effluent; passing at least a portion of the isomerization zone effluent to a stabilizer zone and recovering a stabilizer overhead stream, a bottom stream, and a stripper feed stream; passing the stripper feed stream to a stripping zone and separating the stripper feed stream into a stripper overhead stream and a stripper bottom stream; and recycling at least a portion of the stripper bottom stream to a deisopentanizer zone and passing a stream from the deisopentanizer zone to the isomerization reaction zone. Usually, the stabilizer overhead stream includes one or more C5− hydrocarbons, the bottom stream includes at least about 85%, by weight, one or more C6+ hydrocarbons, and a stripper feed stream including at least about 10%, by weight, one or more C5+ hydrocarbons. Often, a stripper overhead stream includes at least about 5%, by weight, one or more C4− hydrocarbons and a stripper bottom stream includes at least about 90%, by weight, one or more C5+ hydrocarbons.

Abstract: One exemplary embodiment can be an apparatus for isomerizing a hydrocarbon stream rich in a C4 hydrocarbon and/or at least one of a C5 and C6 hydrocarbon. The apparatus can include: a first drier and a second drier adapted to receive a fluid including at least one reactant; and a reaction zone communicating with the first drier to receive the fluid including at least one reactant and with the second drier to receive the regenerant. Generally, the first drier operates at a first condition to dry the fluid including at least one reactant and the second drier operates at a second condition during regeneration with a regenerant. The regenerant can pass through a fluid tapering device for regulating the flow of the regenerant to the reaction zone.

Abstract: An alkylation process including an upfront isomerization zone is described. 100% n-butane or field butanes can be converted into a blend of approximately 60 wt % isobutane and 40 wt % n-butane in the isomerization zone. This blend can be used as the feed to all types of alkylation zones. It stabilizes the feed composition so that the dehydrogenation zone and alkylation zone always operate with the same feed.

Abstract: Processes incorporating a common organic chloride decomposition reactor and chloride treater to be used by both the C4 and C5-6 isomerization reaction zones are described. A portion of the C4 isomerization reaction zone off gas is routed to the C4 HCl absorber, which provides about 85% of the HCl requirement for the C4 isomerization reaction zone. A small amount of the C5-6 isomerization reaction zone off gas is mixed with the C4 isomerization reaction zone off gas portion going to the C4 HCl absorber.

Abstract: A process for producing an isomerized product comprises sending a feed stream comprising butanes, hydrogen and an organic chloride to a butane isomerization reactor containing an isomerization catalyst to convert a portion of normal butanes in said feed stream to iso-butanes in an isomerized stream. The isomerized stream to a stabilizer column to produce a butane stream containing normal, iso-butanes and C5 hydrocarbons; the butane stream is sent to a column to produce an isomerized upper stream and a bottoms stream comprising a mixture of butanes, C5 hydrocarbons and organic chloride. The bottoms stream is sent to an organic chloride decomposition reactor to produce a mixture of HCl, hydrogen and hydrocarbons.

Abstract: Processes and apparatus for isomerizing hydrocarbons are provided. The process comprises isomerizing at least a portion of the hydrocarbon feed stream comprising at least one of C4 to C7 hydrocarbons in the presence of an isomerization catalyst and hydrogen under isomerization conditions to produce a isomerized stream. The isomerized stream is stabilized in a stabilizer to provide a stabilizer off-gas stream comprising chlorides and a liquid isomerate stream. At least a portion of the stabilizer off-gas stream is contacted with an exchange stream to provide an absorber overhead stream and absorber bottoms stream comprising chlorides. The absorber bottoms stream is passed to the isomerization reactor. The liquid isomerate stream is passed to a deisohexanizer column to provide an isomerate product and deisohexanizer side stream.
