    摘要: The invention provides a process for converting hydrocarbons in which said feed is treated in a distillation zone associated with a reaction zone, the feed for the reaction zone being drawn off at the height of at least one draw-off level, the effluent from the reaction zone being re-introduced into the distillation zone at the height of a re-introduction level, said process being characterized in that a liquid effluent is also withdrawn from the distillation zone at the height of a withdrawal level, said liquid effluent being treated in a gas-liquid side separation zone (splitter), the gaseous effluent being re-introduced into the distillation zone and the liquid effluent being recovered as an intermediate cut. This process can be used to reduce the benzene content of a hydrocarbon cut and to recover a naphtha cut.

    摘要: The invention relates to a process for producing high purity isobutene from a hydrocarbon cut essentially comprising olefinic hydrocarbons containing 4 carbon atoms per molecule including isobutene, also butene-1 and butene-2 compounds in a ratio which substantially corresponds to the thermodynamic equilibrium. The process comprises passing the cut into a distillation zone (3) associated with a hydroisomerization reaction zone, the bottom product of the distillation zone comprising butene-2 compoundw being passed into a second distillation zone (4), preferably an extractive distillation zone, to obtain a first effluent comprising butene-2 compounds as its major portion and a second effluent comprising normal-butane as its major portion, the major portion of the first effluent being passed into a skeletal isomerization zone (2) where the linear butenes are at least partially isomerized to isobutene, at least part of the principal effluent from the skeletal isomerization zone being recycled upstream of the reactive distillation zone (1).

    摘要: A process for simultaneously exchanging material and for exchanging heat, material change being effected between a gas phase and at least one liquid phase by contact and passage in opposite directions of the gas phase and of the at least one liquid phase and heat exchange being effected between a compartment (I) and another compartment (II). In compartment (I) a plurality of spacer plates defining material exchange passages are arranged and the material exchange is effected by causing the at least one liquid phase to flow over a substantially vertical or inclined wall of a corrugated spacer plate having perforations and by causing at least a fraction of the gas phase to traverse simultaneously said perforations in a substantially ascending direction to contact said at least one liquid phase. The heat exchange is effected by circulating a heat exchange fluid in the compartment (II) which has a common wall with the compartment (I).
