摘要： This ethylbenzene process involves contacting, in an alkylation zone, a first benzene recycle stream and an ethylene feed stream with an alkylation catalyst to form ethylbenzene. In a transalkylation zone, a polyethylbenzene recycle stream and a second benzene recycle stream are contacted with a transalkylation catalyst to form additional ethylbenzene. The effluents are passed into a dividing wall distillation column where a benzene overhead and a benzene side draw are removed and recycled. An ethylbenzene stream product stream is also removed. The remainder, largely polyethylbenzene and tar, is passed to a polyethylbenzene column for separation. The separated polyethylbenzene is recycled to the transalkylation reactor.

摘要： A process and apparatus for contacting reactants with a particulate catalyst while indirectly heating the reactants with a heat exchange medium improves temperature control by using an intermediate heat exchange fluid and system to prevent overheating of reactants and maintain parallel heating characteristics through multiple reaction-heat exchange zones. The internal flow path minimizes the circulation of the reaction zone heat exchange fluid by incorporating interstage reheating of the reaction zone heat exchange fluid as it passes in series flow. A particularly useful application of the process and apparatus is in the dehydrogenation of ethyl benzene to produce styrene. The process and apparatus can also be used with simultaneous exchange of catalyst particles by an operation that restricts reactant flow while moving catalyst through reaction stacks in which the reactant flow has been restricted.

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： A process for the catalytic reforming of a hydrocarbonaceous feedstock at reforming conditions including a pressure of from about 50 to about 250 psig. is disclosed. A portion of the hydrogen-rich vapor phase recovered from the reforming zone effluent at a relatively low pressure is compressed and recycled to the reforming zone without further purification. The balance of said hydrogen-rich vapor phase, or the net hydrogen, is compressed to a relatively high pressure and recontacted with at least a portion of the liquid hydrocarbon phase recovered from said low pressure separation to effect a further purification of said net hydrogen and to maximize the recovery of C.sub.3 -C.sub.6 + material in the liquid phase.
