    摘要: Savings in the processing of a naphtha boiling range feed containing a thiophene are achieved by fractionating the feed stream in a single dividing wall column to yield a C6-minus overhead stream, a side-draw containing the majority of the C6 and C7 paraffins and olefins, and a bottoms stream comprising C7 and heavier hydrocarbons. A dividing wall column provides better control of the concentration of both thiophene and toluene in the side-draw. Less of the valuable naphtha is lost and the amount of thiophene in the overhead product is minimized.

    摘要: A process for the removal of sulfur-oxidated compounds from a hydrocarbonaceous stream containing sulfur-oxidated compounds wherein the hydrocarbonaceous stream containing sulfur-oxidated compounds is contacted with an adsorbent which selectively adsorbs sulfur-oxidated compounds from the hydrocarbonaceous stream to produce an adsorbent having adsorbed sulfur-oxidated compounds. The loaded adsorbent containing sulfur-oxidated compounds is contacted with a desorbent to produce a desorbent containing sulfur-oxidated compounds and an adsorbent having a reduced content of sulfur-oxidated compounds. The regenerated adsorbent is then used to remove additional sulfur-oxidated compounds.

    摘要: One exemplary embodiment can be a system for separating a plurality of naphtha components. The system can include a column, an overhead condenser, and a side condenser. Generally, the column includes a dividing imperforate wall with one surface facing a feed and another surface facing at least one side stream. Typically, the wall extends a significant portion of the column height to divide the portion into at least two substantially vertical, parallel contacting sections. Typically, the overhead condenser receives an overhead stream including a light naphtha from the column. Usually, a side condenser receives a process stream from the column and returns the stream to the column to facilitate separation. A cooling stream may pass through the overhead condenser and then the side condenser.

    摘要: The selective saturation of unsaturated aliphatic hydrocarbons (e.g., diolefins) in a hydrogenation feed stream comprising an aromatic compound (e.g., benzene) and one or more nitrogen compounds renders it beneficial when the stream or a portion thereof is subsequently treated (e.g., with a zeolitic adsorbent) to remove nitrogen. In particular, the selective saturation of, for example, olefins and diolefins prolongs the life of the nitrogen guard bed. In a representative embodiment, the selective hydrogenation is applied to a recycle benzene-containing stream recovered in the separation section (e.g., from the benzene/toluene splitter overhead) of a styrene production process, prior to treatment with a nitrogen guard bed adsorbent.
