摘要： A diesel or jet fuel distillate product is recovered from a hydrocracking process in an integrated flowscheme wherein the distillate is removed from the hydrocracking zone product column and then passed into a catalytic dewaxing zone. The once-through hydrogen provided in the catalytic dewaxing zone is the makeup hydrogen for the hydrocracking zone. Large economies are realized in terms or reduced capital costs compared to the conventional flowscheme. In addition the severity of the hydrocracking operation is reduced thus extending the life of the hydrocracking catalyst.

摘要： A process for the production of alkylaromatic hydrocarbons uses a working fluid to reduce the costs of separating an unreacted aromatic feed substrate from aromatic hydrocarbon products. Unreacted aromatic substrate is combined with a light hydrocarbon, such as propane, to form a combined effluent stream. The combined effluent stream enters a flash separator where unreacted aromatic substrate is lifted overhead with the light hydrocarbon while heavier aromatic products are recovered below. The aromatic substrate and light hydrocarbon are easily separated in a simple separation zone. Lifting the aromatic substrate with the working fluid reduces the volume of aromatic substrate that remains with the aromatic product so that the more energy intensive separation of the aromatic substrate and aromatic product is performed on a reduced volume of material.

摘要： A FCC product recovery section operates at greater efficiency by recovering separate riser product streams and reactor product streams and quenching and absorbing lighter, more valuable hydrocarbon products from the reactor product stream in separate quench and absorption vessels. The quench and absorbtion vessels are intergrated with a main fractionator and gas concentration section of a typical FCC product recovery section. Heavy hydrocarbons, clarified oil and/or cycle oil absorb hydrocarbons from the reactor product stream in the quench and absorption vessels and return the absorbed products to the main fractionator while net gasoline product from the reactor product stream enter the primary absorber of the gas concentration section. This arrangement is particularly useful in increasing the product recovery capacity of an existing FCC product separation section.
摘要翻译： FCC产品回收部分通过回收单独的提升管产物流和反应器产物流以及在单独的骤冷和吸收容器中从反应器产物流中淬火和吸收更轻，更有价值的烃产物而以更高的效率运行。淬火和吸收容器与典型FCC产品回收部分的主分馏器和气体浓缩部分相结合。重质烃，澄清油和/或循环油在骤冷和吸收容器中从反应器产物流中吸收烃，并将吸收的产物返回到主分馏器，而来自反应器产物流的净汽油产物进入气体浓度段的主吸收器。这种布置在提高现有FCC产品分离部分的产品回收能力方面特别有用。

摘要： An FCC process and apparatus is arranged to provide a low volume dilute disengagement zone in a reactor vessel and a quench zone immediately downstream of the reactor vessel. A vented riser that provides an open discharge of catalyst and gaseous products is directly discharged into a reactor vessel. The interior of the reactor vessel is arranged such that the outlet of the reactor riser is located close to and directed at the top of the reactor vessel. The reactor vessel operates with a dense bed of catalyst having an upper bed level that is only a short distance below the outlet of the reactor riser. The cyclone separators are located to the outside of the reactor riser and circulate catalyst back to the dense bed of the reactor section. The quenching takes place downstream of the cyclone separators.

摘要： A process flow for hydrogen-producing processes such as reforming or dehydrocyclodimerization is disclosed. A portion of a C.sub.3 or C.sub.4 feed stream is flashed to provide reflux cooling for a product recovery fractionation column. The cool overhead of this column and a second portion of the feed stream are used to cool the still uncondensed portion of the partially condensed reaction zone effluent stream prior to passage of this uncondensed material into a final low temperature separation stage. A second feature is the reboiling of a fractionation column with hot compressed gas to perform interstage cooling in the product recovery compression section.

摘要： Hydrocarbon feedstock is dispersed in an FCC riser by directing jets of atomized feed droplets into a flowing stream of catalyst particles in a direction substantially perpendicular to the axis of the riser. By directing the feed into the riser in a substantially perpendicular direction feed is more quickly dispersed across the entire cross section of the riser. By quickly dispersing feed the mixture of hydrocarbons and catalyst particles is completely mixed after traveling only a short distance along the riser from the point of feed introduction. Reducing this contact zone length improves the quality of riser products by eliminating variations in the contact time between the feed and catalyst. In addition to the short contact zone length this invention also combines the desirable features of catalyst pre-acceleration and feed atomization. The apparatus used for practicing this invention may also include a central strike surface in the riser to prevent erosion of the riser wall from the radially directed feed jets.

摘要： Middle distillate petroleum streams are hydrotreated to produce a low sulfur and low aromatic product in a process employing three reaction zones in series. Hydrogen flows between the reaction zones countercurrent to the hydrocarbons. Hydrogen sulfide is removed from effluent of the first two reaction zones by hydrogen stripping. The second and third reaction zones employ a sulfur-sensitive noble metal hydrogenation catalyst. Operating pressure increases and temperature decreases from the first to third reaction zones.
