摘要： The invention relates to a process for treating an hydroalcoholic feedstock comprising ethanol and butanol in order to produce an ethanol-rich effluent, a water-rich effluent and a butanol-rich effluent, comprising a) a water-ethanol separation step comprising a distillation column fed with said hydroalcoholic feedstock and comprising at least 14 theoretical plates, a molar reflux ratio of less than or equal to 1.2, a side withdrawal in the butanol accumulation zone and two injections of recycled streams resulting from steps b) and c); b) a demixing step comprising a section for mixing the stream withdrawn in step a) and the fraction withdrawn in step c), and a decanting section, the heavy phase being recycled to the distillation column of step a); c) a butanol separation step comprising a distillation column fed with the light phase resulting from step b), comprising a side withdrawal of a water/butanol/ethanol fraction recycled to the mixing section of step b) and producing a butanol-rich effluent and an ethanol-water distillate which is recycled to the distillation column of step a). This process appears to be particularly advantageous for the treatment of the hydroalcoholic effluent from the Lebedev process.

摘要： The present invention describes a process for steam reforming natural gas, comprising a steam reforming exchanger-reactor (3000), a reactor for converting CO to CO2 (3100), and a PSA hydrogen purification unit (4300), with a view to producing a synthesis gas in which the heat necessary for the steam reforming reaction is supplied by a first combustion chamber (3100) connected to a second combustion chamber (3200) generating fumes in order to produce a very high degree of thermal integration.

摘要： The invention relates to a plant and to a method for chemical looping oxidation-reduction combustion of a gaseous hydrocarbon feed, for example natural gas essentially containing methane. According to the invention, catalytic pre-reforming of the feed is performed in a pre-reforming zone comprising a fixed reforming catalyst, while benefiting from a heat transfer between the reduction or oxidation zone of the chemical loop and the pre-reforming zone adjoining the reduction or oxidation zone. Pre-reforming zone (130) and oxidation zone (110) or pre-reforming zone (130) and reduction zone (120) are thus thermally integrated within the same reactor (100) while being separated by at least one thermally conductive separation wall (140).

摘要： The invention relates to a process for the steam cracking of a feedstock composed of at least 80% by weight, in particular of at least 90% by weight, of ethane, the process comprising a steam cracking of the feedstock in a furnace (2), then a quenching of the pyrolysis products, then a compression operation, then a series of successive operations on the products resulting from the quenching, the said series of operations comprising a washing operation, followed by a drying operation and at least one compression operation, and finally a fractionation by cryogenic distillation. A selective hydrogenation operation, followed by a catalytic conversion operation, will be inserted into the said process, after the drying operation and before the fractionation, in order to partially convert the ethylene predominantly into propylene.
