摘要： The invention relates to a process (100) for deriving polymerizable aromatic compounds having nine carbon atoms (S) in which a component mixture (B) is formed at least partially by steam cracking, in which the component mixture (B) is subjected to a workup (2, 3, 4, 5) comprising a gasoline removal (5) and thereafter is a compression (8) and a fractionation (10), and wherein one or more pyrolysis gasoline fractions (H, L) is or are formed in the gasoline removal (5) and/or the compression (8). The invention provides that a separation feed is formed which comprises predominantly exclusively pyrolysis gasoline from the or at least one of the pyrolysis gasoline fractions (H, L) and that the separation feed is subjected to a separation (7), wherein in the separation (7) at least one fraction (P) enriched in aromatic compounds having nine carbon atoms compared to the separation feed is formed. A corresponding plant likewise forms part of the subject matter of the invention.

摘要： The invention relates to a method for a low-temperature air separation in which an air separation unit is used comprising a first rectification column and a second rectification column. The first rectification column is operated at a first pressure level, and the second rectification column is operated at a second pressure level below the first pressure level. Fluid which is oxygen-enriched compared to atmospheric air is drawn from the first rectification column in the form of one or more first material flows. At least one fraction of the fluid which has been drawn from the first rectification column in the form of the one or more first material flows is heated in a heat exchanger; a fraction of the fluid which has been heated in the heat exchanger is compressed using a compressor and is returned to the first rectification column.

摘要： A method for low temperature separation of air using an air separating installation having a distillation column system which has a first, a second, a third and a fourth separating unit. Compressed and cooled air is fed into the first separating unit. An oxygen-enriched, nitrogen-depleted, argon-containing first sump liquid and a nitrogen-enriched, oxygen-depleted first head gas are formed by means of the first separating unit. An oxygen-rich second sump liquid and an argon-enriched second head gas are formed by means of the second separating unit. A liquid return to the second separating unit is provided by means of the third separating unit. A fourth sump liquid and a fourth head gas are formed by means of the fourth separating unit, and the fourth sump liquid is at least partially returned to the second separating unit.

摘要： The invention relates to a method for producing one or more olefins and one or more carboxylic acids, in which one or more paraffins is or are subjected to an oxidative dehydrogenation. For the oxidative dehydrogenation, a reactor (10) having a plurality of reaction zones (11, 12, 13) is used, a gas mixture comprising the one or more paraffins is successively passed through the reaction zones (11, 12, 13), and at least two of the reaction zones (11, 12, 13) are subject to varying temperature influences. The invention also relates to a corresponding system (100).

摘要： The invention relates to a process for separating a component mixture (K) comprising hydrogen, methane, hydrocarbons having two carbon atoms and hydrocarbons having three or more carbon atoms, wherein in a deethanization at least a portion of the component mixture (K) is subjected to a first partial condensation by cooling from a first temperature level to a second temperature level at a first pressure level to obtain a first gas fraction (G1) and a first liquid fraction (C1), at least a portion of the first gas fraction (G1) is subjected to a second partial condensation by cooling from the second temperature level to a third temperature level at the first pressure level to obtain a second gas fraction (G4) and a second liquid fraction (C2), and at least a portion of the first liquid fraction (C1) and at least a portion of the second liquid fraction (C2) are subjected to a rectification to obtain a third gas fraction (G3) and a third liquid fraction (C3+). The first liquid fraction (C1) or its part subjected to the rectification and the second liquid fraction (C2) or its part subjected to the rectification are expanded to a second pressure level and the rectification is carried out at the second pressure level, the first pressure level being 25 to 35 bar and the second pressure level being 14 to 17 bar. An overhead gas formed during the rectification is cooled to −25 to −35° C. and partially condensed, wherein a condensed portion of the overhead gas is used partially or completely as a reflux in the rectification and an uncondensed portion of the overhead gas is provided partially or completely as the third gas fraction (G3). The present invention likewise provides a corresponding plant (100, 200).

摘要： A reactor has a reactor vessel and one or more reaction tubes. One or more power input elements are guided into the reactor vessel for the electrical heating of the reaction tube(s). The one or more power input elements each have a rod-shaped section, and the rod-shaped section(s) each run in a respective wall passage through a wall of the reactor vessel. A connection chamber into which the rod-shaped section(s) project is arranged outside the reactor vessel and adjacent to the wall of the reactor vessel through which the rod-shaped section(s) run in their wall passages. Gas feed means apply an inerting gas to the connection chamber, and the wall passages with the rod-shaped sections received therein in a longitudinally-movable manner are designed to be gas-permeable so that at least a portion of the inerting gas fed into the connection chamber flows out into the reactor vessel.
