    • The invention relates to a method for producing propene from propane. Said method comprises the following steps: A) a feed gas stream (a) containing propane is prepared; B) the feed gas stream (a) containing propane, is introduced with optionally water vapour and optionally, an oxygen-containing gas stream into a dehydrogenation zone and then the propane is dehydrogenated to form propene, and a product gas stream (b) containing propane, propene, methane, ethane, ethene, hydrogen, optionally carbon monoxide, carbon dioxide, water vapour and oxygen, is obtained; C) the product gas stream (b) is cooled, optionally compressed and then water vapour is separated by condensation and a product gas stream (c) depleted in water vapour is obtained; D) the product gas stream (c) is brought into contact with a selectively active adsorber which selectively adsorbs propene in the selected adsorption conditions, and an adsorber charged with propene and a gas stream (d2) depleted in propene and containing propane, methane, ethane, ethene and hydrogen, carbon monoxide and carbon dioxide are obtained; E) a gas stream (e1) containing propene is released from the adsorber charged with propene by reducing the pressure and/or heat of the adsorber.

    • The invention relates to a method for predicting a time-variant parameter of a technical process which has at least two types of working phases that proceed repeatedly one after the other and have a respective variable duration. In a learning mode of the method according to the invention, every type of working phase proceeds several times over an empirical interval, the effective duration of the respective working phase is measured for every type of working phase during a plurality of passages and this duration is collected jointly for all working phases of the same type that have been analyzed in the past in an orderly manner so that a frequency distribution of the duration of the corresponding type of working phase is obtained. In a prognostic mode, the current type of working phase is determined at a current point in time, the phase duration passed so far is determined and a prognostic value of the parameter in at least one point in time in the future is determined using the frequency distribution of the duration of the corresponding type of working phase determined in the learning mode.

    • The present invention relates to processes for preparing propene from propane, comprising the steps: A) a feed gas stream a comprising propane is provided; B) the feed gas stream a comprising propane, if appropriate steam and if appropriate and 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, hydrogen, if appropriate carbon monoxide, carbon dioxide, steam and oxygen; C) the product gas stream b is cooled, if appropriate compressed and steam is removed by condensation to obtain a steam-depleted product gas stream c; D) the product gas stream c is contacted with a selective adsorbent which adsorbs propene selectively under the selected adsorption conditions to obtain a propene-laden adsorbent and a propene-depleted gas stream d2 comprising propane, methane, ethane, ethene and hydrogen, carbon monoxide and carbon dioxide; E) a propene-comprising gas stream e1 is released from the propane-laden adsorbent by pressure reduction and/or heating of the adsorbent.
