Abstract: Processes and apparatuses for separating chlorides from a butane product stream by removing chlorides from a portion of said feed stream in a rectification section of the separation zone. The rectification section may be in a rectification column which may be combined with a stripper column. Alternatively, a wall may be used to provide the rectification section in a fractionation column. The processes and apparatuses can be used in both new designs and revamped designs.

Abstract: Processes and apparatuses for producing a C8 aromatic isomer product are provided. The process comprises introducing a reformate stream comprising aromatic hydrocarbons to a reformate splitter column to provide a plurality of streams. One or more streams comprising at least one stream from the plurality of streams is passed to a reformate upgrading unit to obtain an upgraded reformate stream. The upgraded reformate stream is passed to an aromatics stripper column to provide an aromatics stripper sidedraw stream comprising C8 aromatic hydrocarbons. The aromatics stripper sidedraw stream is passed to a xylene separation unit to provide the C8 aromatic isomer product and a raffinate product stream. At least a portion of the raffinate product stream is processed in a liquid phase isomerization unit to obtain an isomerized stream.

Abstract: Methods and apparatuses for processing hydrocarbons are provided. In one embodiment, a method for processing hydrocarbons includes fractionating a feed stock to form a C6-C10 naphtha stream and a C11+ hydrocarbon stream. The method reforms the C6-C10 naphtha stream. Further, the method cracks the C11+ hydrocarbon stream to form a stream of C6-C10 hydrocarbons and extracts aromatics from the stream of C6-C10 hydrocarbons to form an extract stream. The method includes combining the C6-C10 naphtha stream and the extract stream containing the aromatics. Also, the method includes processing the C6-C10 naphtha stream and the extract stream in an aromatics complex to form selected aromatic products. Further, the embodiment may include reforming raffinate streams.

Abstract: Processes for increasing an octane value of a gasoline component by dehydrogenating a stream comprising C7 hydrocarbons and methylcyclohexane in a first dehydrogenation zone to form an intermediate dehydrogenation effluent, and then dehydrogenating the intermediate dehydrogenation effluent in a second dehydrogenation zone to form a C7 dehydrogenation effluent. The C7 dehydrogenation effluent has an increased olefins content compared to an olefins content of the intermediate dehydrogenation effluent. The first dehydrogenation zone is operated under conditions to convert methylcyclohexane to toluene and minimize cracking reactions. The intermediate dehydrogenation effluent may be heated before being passed to the second dehydrogenation zone.

Abstract: A reforming process is described. The reforming process includes introducing a hydrocarbon stream comprising hydrocarbons having 5 to 12 carbon atoms into a reforming zone containing reforming catalyst, the reforming zone comprising at least two reformers, each reformer having a set of reforming operating conditions, to produce a reformate effluent, wherein the last reformer contains less catalyst than the next to the last reformer.

Abstract: A process and apparatus for making aromatics are described. The process includes reforming a naphtha stream in a reforming zone to form a reformer effluent comprising aromatic compounds and non-aromatic compounds, wherein at least a portion of the aromatic compounds contain alkyl groups. The reformer effluent is heated and passed directly to an acid cracking reaction zone. The non-aromatic compounds are selectively cracked and at least a portion of the alkyl groups on the aromatic compounds are selectively dealkylated in the presence of an acid cracking catalyst to form a cracked reformer effluent comprising the aromatic compounds and cracked olefins.
