  • Patent number: 10822548
    Abstract: 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.

  • Patent number: 10473325
    Abstract: 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).

  • Patent number: 9222724
    Abstract: The method provides liquefaction of a natural gas by carrying out the following stages: cooling the natural gas; feeding the cooled natural gas into a fractionating column so as to separate a methane-rich gas phase and a liquid phase rich in compounds heavier than ethane; and liquefying the methane-rich stream so as to obtain the liquid natural gas. According to the invention, the operating conditions in the fractionating column are so selected that said liquid phase comprises a molar proportion of methane ranging between 10% and 150% of the molar proportion of ethane.
