    Abstract: Procedimiento para la obtención de propeno a partir propano, con los siguientes pasos: A) se prepara un flujo de gas de alimentación a que contiene propano; B) el flujo de gas de alimentación a que contiene propano, eventualmente, vapor de agua y, eventualmente, un flujo de gas que contiene oxígeno, son suministrados a una zona de deshidrogenación y el propano es sometido a una deshidrogenación a propeno, en la cual se obtiene un flujo de gas producto b que contiene propano, propeno, metano, etano, eteno, monóxido de carbono, dióxido de carbono, vapor de agua, eventualmente, hidrógeno y, eventualmente, oxígeno; C) el flujo de gas producto b es refrigerado, eventualmente, comprimido, y el vapor de agua es eliminado por condensación, obteniéndose un flujo de gas producto c empobrecido en vapor de agua; D) En una primera zona de absorción, el flujo de gas producto c es puesto en contacto con un absorbente que actúa de manera selectiva, que absorbe de manera selectiva el propeno, de este modo se obtienen un flujo de absorbente d1 cargado, esencialmente, con propeno, y un flujo de gas d2 que contiene propano, propeno, metano, etano, eteno, monóxido de carbono, dióxido de carbono, eventualmente, hidrógeno y, eventualmente, oxígeno; E) Eventualmente, el flujo de absorbente d1 es distendido en una primera zona de desorción hasta alcanzar una presión más baja, se obtienen de este modo un flujo de absorbente e1 cargado con propeno y un flujo de gas e2 que contiene propeno, asimismo, el flujo de gas e2 es reconducido a la primera zona de absorción, F) A partir de un flujo de absorbente d1 o e1 cargado, esencialmente, con propeno, en, al menos, una segunda zona de desorción y por distensión, calentamiento y/o despojamiento del flujo de absorbente d1 o e1 se libera un flujo de gas f1 que contiene propeno, asimismo, se recupera el absorbente de acción selectiva.

    Abstract: Disclosed is a method for the heterogeneously catalyzed partial direct oxidation of propane and/or isobutane. According to said method, target product is separated from the product gas mixture obtained in the reaction stage in a reprocessing stage, the remaining product gas mixture is divided into two partial quantities having the same composition, one partial quantity is redirected into the reaction stage while the other partial quantity is discharged, and both the reaction stage and the reprocessing stage are operated at an increased pressure.

    Abstract: A process comprising: (a) distilling a melt comprising crude alkanesulfonic acid to completely or partly remove low boilers, wherein the low boilers are drawn off at the top of a distillation column or of a one-stage evaporation apparatus and a material stream comprising alkanesulfonic acid, high boilers and residual low boilers is withdrawn at the bottom of the distillation column or of the one-stage evaporation apparatus, (b) sending the stream comprising alkanesulfonic acid, high boilers and residual low boilers into a melt crystallization as the starting melt to obtain crystals formed from the alkanesulfonic acid, hydrates of the alkanesulfonic acid or a mixture of both suspended in mother liquor, (c) performing a solid-liquid separation to remove the crystals from the mother liquor, and (d) optionally washing the crystals to remove mother liquor adhering to the crystals.

    Abstract: A process for preparing propene from propane, comprising the steps: A) a feed gas stream a comprising propane is provided; B) the fed gas stream a comprising propane, if appropriate steam and, if appropriate, an oxygenous gas stream are fed into a dehydrogenation zone and propane is subjected to a dehydrogenation to propene to obtain a product gas stream b comprising propane, propene, methane, ethane, ethene, carbon monoxide, carbon dioxide, steam, if appropriate hydrogen and, if appropriate, oxygen; C) product gas stream b is cooled, if appropriate condensed and steam is removed by condensation to obtain a steam-depleted product gas stream c; D) product gas stream c is contacted in a first absorption zone with a selective, inert absorbent which selectively absorbs propene to obtain an absorbent stream d1 laden substantially with propene and a gas stream d2 comprising propane, methane, ethane, ethene, carbon monoxide, carbon dioxide and hydrogen; E) if appropriate, the absorbent stream d1 is decompressed to a lower pressure in a first desorption zone to obtain an absorbent stream e1 laden substantially with propene and a gas stream e2 comprising propene, and gas stream e2 is recycled into the first absorption zone, F) from the absorbent stream d1 or e1 laden substantially with propene, in at least one second desorption zone, by decompression, heating and/or stripping the absorbent stream d1 or e1, a gas stream f1 comprising propene is released and the selective absorbent is recovered.
