Abstract: Processes for producing aromatics from a naphtha feedstream are provided. An exemplary process includes passing the feedstream to a fractionation unit, thereby generating a first stream including hydrocarbons having less than 8 carbon atoms and a second stream including hydrocarbons having at least 8 carbon atoms. The first stream is passed to a first reformer operated at a first set of reaction conditions to generate a first product stream. The first set of reaction conditions includes a first temperature and a first pressure. The second stream is passed to a second reformer operated at a second set of reaction conditions to generate a second product stream. The second set of reaction conditions includes a second temperature and a second pressure. The first pressure is lower than the second pressure.

Abstract: A process for a liquid phase selective hydrogenation of acetylene to ethylene in a reaction zone. In order to decrease the selectivity to C4+ hydrocarbons, the concentration of acetylene in solvent is lowered by recycling solvent, using a split feed injection, or both. The streams can be split in to equal or unequal portions. A hot separator may be used to separate solvent from the reactor effluent, and the solvent may be recovered and used to decrease the concentration of acetylene in the solvent.

Abstract: A process for cleaning a reactor, the reactor comprising a shell including catalyst for selectively converting hydrocarbons. The process includes removing catalyst from the reactor and deploying a robot into the reactor. A cleaner from the robot is applied onto a surface within the shell of the reactor that includes a foulant. The cleaner is adapted to remove the foulant from the surface within the shell of the reactor. The cleaner may be one of light radiation, heat radiation, ultra-high pressure fluid, and liquid nitrogen.

Abstract: Embodiments of apparatuses and methods for removing acid gas from sour gas are provided. In one example, an apparatus comprises an absorption zone. The absorption zone is configured for contacting the sour gas with an absorbent solvent that is at a first predetermined temperature of less than about 0° C. to remove the acid gas and form a treated gas stream that includes entrained absorbent solvent. A heat exchanger or heater is configured to heat the treated gas stream to a second predetermined temperature of greater than about 0° C. to form a partially heated treated gas stream. A water wash zone is configured for contacting the partially heated treated gas stream with water to remove the entrained absorbent solvent and form a solvent-depleted treated gas 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.
