摘要： A system and method of concentrating spent caustic at a refinery has a multi-stage flash drum for separating a spent caustic stream into an overhead output stream including vaporized water and volatile organic compounds, and a concentrated spent caustic output stream. The system also has a condenser for condensing the overhead output stream, and a separator for separating the condensed overhead output stream into a volatile organic compound stream, a liquid hydrocarbon stream and a water stream. The system further has an ejector for applying a vacuum to the flash drum to vaporize the spent caustic stream at a reduced temperature, and to the separator to remove the volatile organic compound stream. The volatile organic compounds are removed from the overhead of the separator through the ejector to a burner of a fired heater.

摘要： Nitrogenous compounds especially bases such as ammonia vapor are used to control the operation of a hydrocracker or catalytic dewaxer. Catalyst activity and selectivity may be controlled by addition of the base to the feed, for example, to control the balance between isomerization and hydrocracking in an operation using a zeolite beta catalyst. Runaway conditions may be controlled by the addition of nitrogenous compounds to regulate the temperature profile within the reactor.

摘要： An inlet distributor system for a fixed bed catalyst reactor which includes an inlet deflector cone positioned to deflect liquid in cooperation with a splash plate onto a liquid distributor trough positioned therebelow. An upper tray is positioned beneath the distributor trough to receive liquid therefrom. The upper distributor tray has a series of risers in spaced position thereon and extending above and below the upper distributor tray. The risers are hollow and open above and below the upper distributor tray to permit vapor to pass through the tray and each riser has a plurality of weir slots cut into its outer surface through which liquid can pass through the tray. A lower distributor tray is positioned beneath the upper distributor tray to receive liquid passing through the weir slots of the risers. The lower distributor tray has a series of risers and downpipes thereon arranged in a predetermined pattern. Each of the risers and downpipes in said pattern extend above and below the lower distributor tray and have openings above and below the lower distributor tray to form a through passageway for liquid to pass through the tray when received from the upper distributor tray. The passageway in the downpipes is formed by an axial bore therethrough and the passageway in the risers is formed by its hollow tubular configuration open at the bottom and having a side opening therein above the upper surface of the lower distributor tray each riser includes another upper opening above the lower distributor tray to permit vapor to pass through the tray. The pattern of risers and downpipes provide an advantageous arrangement of passageways for liquid to be distributed to the catalytic bed therebelow.

摘要： This invention is directed to an improved process scheme to process sour feed in the reaction section of the process unit, including isomerization dewaxing with zeolite beta. The instant invention employs countercurrent flow in the fixed bed of the MIDW(Mobil Isomerization Dewaxing) reactor (the reactor in which isomerization dewaxing occurs) with recycle gas being the gas stream in the MIDW bed. With this arrangement hydrodesulfurization(HDS) and MIDW occur in an integrated process.

摘要： This invention provides a fixed bed of nonuniformly sized grade catalyst particles for hydrocracking or hydrodesulfurization. The graded particles are arranged with the largest particles in either the upstream or the downstream portion of the bed. In either case, when compared with the conventional bed of uniformly sized particles, the graded bed of this invention shows enhanced hydrocarbon conversion activity for heavy oils over a useful range of conversion. Such catalyst bed is particularly useful in moderate hydrocracking operating at less than 1000 psig (7000 kPa) pressure.

摘要： A process for reducing NOx emissions and an FCC process using same as a flue gas cleanup stage are disclosed. Gas containing NOx and entrained catalyst fines is passed up through a bed of catalyst at a sufficient velocity to expand and fluidize the catalyst bed. Particulates deposited on the catalyst are abraided or elutriated away by fluidization, preventing fouling of the DeNOx catalyst. A low pressure drop design, with vertical, perforate gas distributors covered by the bed is also disclosed.

摘要： A process for the isomerization of C.sub.4 and higher molecular weight hydrocarbons, preferably C.sub.4 to C.sub.6 paraffins with high C.sub.6 cyclics content. A C.sub.5 to C.sub.6 hydrocarbon stream is isomerized in a first isomerization reaction zone and a C.sub.4 hydrocarbon stream is isomerized in a second isomerization reaction zone. At least one or both of the effluent streams from the first and second isomerization zones are conveyed to a gas-liquid separator which separates a hydrogen-rich recycle stream. At least a portion of the hydrogen-rich recycle stream is conveyed to the C.sub.5 to C.sub.6 hydrocarbon feed stream and at least a portion of the hydrogen-rich recycle stream is conveyed to the C.sub.4 hydrocarbon feed stream whereby the hydrogen recycle stream is shared during both the C.sub.4 isomerization reaction and the C.sub.5 to C.sub.6 isomerization reaction. The product stream is conveyed to a shared stabilizer which removes the gaseous and volatile components. The product stream can be fractionated to recover the separate C.sub.4 to C.sub.6 isoparaffins and normal paraffins and naphthenic compounds.
