    Abstract: The invention concerns a method for producing propene from propane, said method consisting in: A) preparing an input gas stream (a) containing propane; B) introducing the input gas stream (a), containing propane, optionally water vapour and optionally an oxygen-containing gas stream, into a dehydrogenation zone then dehydrogenating propane to form propene, a product gas stream (b), containing propane, propene, methane, ethane, ethene, nitrogen, carbon monoxide, carbon dioxide, water vapour, optionally hydrogen and optionally oxygen, being obtained; C) cooling and optionally compressing the product gas stream (b) then separating water vapour by condensing a product gas stream (c) depleted in water vapour (c) being obtained; D) separating the non-condensable gas constituents or with low boiling point by contacting the product gas stream (c) with an inert absorbent then by desorbing the gases dissolved in said inert absorbent, a C 3 hydrocarbon stream (d1) and a residual gas stream (d2) containing methane, ethane, ethene, nitrogen, carbon monoxide, carbon dioxide, optionally hydrogen and optionally oxygen, being obtained; E) cooling and optionally compressing the C 3 hydrocarbon stream (d1), a gaseous or liquid C 3 hydrocarbon stream (e1) being obtained; F) optionally introducing the C 3 hydrocarbon stream (e1) into a first distillation zone then separating same by distillation into a propane and propene stream (f1) and a stream (f2) containing ethane and ethene; G) introducing the stream (e1) or (f1) into a (second) distillation zone then separating by distillation into a propene stream (g1) and a propane stream (g2), the stream (g2) being recycled at least partly to the dehydrogenation zone.

    Abstract: The invention relates to a method for producing aromatic hydrocarbons from a C 1 -C 4 alkane or a mixture of C 1 -C 4 alkanes. Said method is characterized in that a) an educt flow A containing a C 1 -C 4 alkane or a mixture of C 1 -C 4 alkanes is brought in contact with a catalyst, and some of the C 1 -C 4 alkane or some of the mixture of C 1 -C 4 alkanes is reacted to aromatic hydrocarbon/s, b) the product flow B resulting from step a) is separated into a low-boiling flow C containing the main portion of the hydrogen and the non-reacted C 1 -C 4 alkane or mixture of C 1 -C 4 alkanes, and a high-boiling flow D or several high-boiling flows D' containing the main portion of the obtained aromatic hydrocarbon, and c) the low-boiling flow C is fed to another process consuming C 1 -C 4 alkane, the hydrogen contained in the low-boiling flow C being optionally eliminated beforehand.
