Abstract: A process increases the concentration of normal paraffins in a feed stream comprising separating a naphtha feed stream into a normal paraffin rich stream and a non-normal paraffin rich stream. A naphtha feed stream may be separated into a normal paraffin stream and a non-normal paraffin stream. An isomerization feed stream may be taken from the non-normal paraffin stream and isomerized over an isomerization catalyst to convert non-normal paraffins to normal paraffins and produce an isomerization effluent stream. The isomerization effluent stream may be separated into a propane stream and a C4+ hydrocarbon stream optionally in a single column. The C4+ hydrocarbon stream may be recycled to the step of separating a naphtha feed stream.

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 an 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 a dried feed stream to remove chlorides from the stabilizer off-gas stream. The dried feed stream is not cooled before absorbing the chlorides. A portion of the dried feed stream may bypass the absorbing section. A chiller is disposed on top of the vessel with the absorbing section.

Abstract: A process for the recovery of C4 hydrocarbons from a C5/C6 isomerization zone. A portion of the effluent stream from the C5/C6 isomerization zone comprising C4 hydrocarbons is combined in a stabilizer section with an effluent from a C4 isomerization zone. In order to increase the C4 hydrocarbons in the effluent stream from the C5/C6 isomerization zone, a chilling zone may be used.

Abstract: Embodiments of methods and apparatuses for isomerization of paraffins are provided. In one example, a method comprises the steps of compressing a C4− hydrocarbons-containing stabilizer vapor stream to form a compressed C4− hydrocarbons-containing stabilizer stream. A C4 hydrocarbons-containing feed stream that comprises unbranched C4 hydrocarbons is contacted with a chloride-promoted isomerization catalyst in the presence of hydrogen to form a branched C4 hydrocarbons-containing reaction zone effluent. At least a portion of the compressed C4− hydrocarbons-containing stabilizer stream is combined with the branched C4 hydrocarbons-containing reaction zone effluent to form a C4 hydrocarbons-containing combined stream. The C4 hydrocarbons-containing combined stream is separated into a C3− hydrocarbons-containing stabilizer vapor stream and a C4 hydrocarbons-rich product stream that comprises branched C4 hydrocarbons.

Abstract: Processes and apparatus for isomerizing hydrocarbons are provided. The process comprises providing a feed stream comprising C5, C6 and C7+ hydrocarbons. The feed stream is separated to produce a first stream rich in C5 and C6 hydrocarbons and a second stream rich in benzene and C7+ hydrocarbons. The first stream is isomerized in the presence of isomerization catalyst and hydrogen in an isomerization zone under isomerization conditions to produce an isomerized stream. The second stream is contacted with a benzene saturation catalyst at benzene saturation conditions to produce a saturation effluent stream comprising cyclohexane.

Abstract: A process for heating a feed stream to an isomerization zone by passing the feed stream though heat exchangers and heating the feeds stream with reactor effluent from the isomerization zone. The effluent from the last reactor is passed to a stabilization column and then a separation column, preferably without heating the feed stream. The separation column may also be heated with effluent from a reactor in the isomerization zone.

Abstract: Embodiments of apparatuses and methods for separating a paraffin isomerization-zone effluent are provided. In one example, an apparatus comprises a DIB column configured for fractionating the paraffin isomerization-zone effluent to form a branched C4 hydrocarbon-rich stream. The DIB column comprises a vessel. The vessel comprises a cylindrical wall that extends vertically and that encloses an internal cylindrical volume having a lower portion extending to an upper portion. An internal swage is disposed in the lower portion of the internal cylindrical volume. A plurality of fractionation trays includes an upper fractionation tray that is disposed in the internal cylindrical volume above the internal swage and a lower fractionation tray that is disposed in the internal swage. The lower fractionation tray has a smaller diameter than the upper fractionation tray.

Abstract: A process increases the concentration of non normal paraffins in a feed stream comprising separating a naphtha feed stream into a normal paraffin rich stream and a non-normal paraffin rich stream. The non-normal paraffin rich stream is isomerized over an isomerization catalyst to convert non-normal paraffins to normal paraffins, hydrocrack C5+ hydrocarbon to C2-C4 paraffins and produce an isomerization effluent stream. The isomerization effluent stream is separated into a C3− off gas, C4 rich stream and C5+ stream that is recycled to the naphtha feed stream. A depentanizer column may be positioned to either remove C6+ from the naphtha feed stream or from a bottoms stream from a stabilizer column. The amount of C2-C4 paraffins that are provided is increased from about 55% to as much as 77% and even more with further modifications including operating at higher temperatures or increasing the volume of catalyst.

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.
