摘要： This invention relates to a method of producing purified methyl isobutyl ketone (MIBK) comprising subjecting a feed stream containing MIBK and impurities to a first distillation procedure from which acetone is recovered and a bottom product containing MIBK and impurities is withdrawn. This bottom product is fed to a second distillation column, where a vapour overhead product is withdrawn, condensed and fed to an overhead liquid-liquid separator. Part of an organic phase from the overhead liquid-liquid separator is fed to the second distillation column and part is fed to a third distillation column. A vapour overhead product is withdrawn from the third column which is condensed in the same said condensor. The condensed product is fed to the same said overhead liquid-liquid separator, and purified MIBK is withdrawn from the third distillation column. This invention also relates to an apparatus used in such a method.

摘要： A process (8, 108) to separate a multi-component hydrocarbon stream (10.1 ) which includes ethylene and other components with at least some of the components being present in a plurality of phases, is provided. The process (8,108) includes in a first flash stage (16), flashing the multi-component hydrocarbon stream (10.1 ), from an elevated pressure and temperature to a pressure in the range of 10 -18 bar(a), producing a first ethylene-containing vapour stream (16.1 ) at a pressure in the range of 10 - 18 bar(a) and a multi-phase stream (16.2) which includes some ethylene. In a second flash stage (20), the multi-phase stream (16.2) is flashed to a pressure of less than 6 bar(a), producing a second vapour stream (20.1 ) at a pressure of less than 6 bar(a) and a bottoms stream (20.2). The first ethylene-containing vapour stream (16.1 ) is removed from the first flash stage (16), the second vapour stream (20.1 ) is removed from the second flash stage (20) and the bottoms stream (20.2) is removed from the second flash stage (20).

摘要： A process (10) for polymerising or oligomerising a hydrocarbon includes feeding a liquid hydrocarbon reactant (32) and a liquid evaporative cooling medium into a bulk liquid phase (14) which includes polymeric or oligomeric product admixed with a catalyst, and allowing at least a portion of the liquid hydrocarbon reactant and the liquid evaporative cooling medium to vapouhse to form bubbles rising through the bulk liquid phase (14), with the hydrocarbon reactant polymerising or oligomerising to form the polymeric or oligomeric product and with the evaporation of both the liquid hydrocarbon reactant and the liquid evaporative cooling medium effecting heat removal from the bulk liquid phase (14). Gaseous components are withdrawn (26) from a head space, cooled (28) and separated (30). Condensed hydrocarbon reactant and condensed cooling medium are recycled (32) to the bulk liquid phase (14).
