A reactor includes a reactor vessel and one or more reaction tubes A number of tube sections of the one or more reaction tubes in each case run between a first region and a second region in the reactor vessel. For the electrical heating of the tube sections, the tube sections in the first region can be electrically connected to (a) current connection(s) of a current source. In the first region, current feed arrangements are provided; in each case one or in each case one group of the tube sections are electrically connected, and each comprise (a) contact passage(s) that in each case adjoin(s) at least one of the tube sections in the first region. A wall of the contact passages in each case is connected to a current feed element that has a rod-shaped section that runs at a wall passage through a wall of the reactor vessel.

Reactor and method for carrying out a chemical reaction

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.

A reactor for carrying out a chemical reaction has a reactor vessel, one or more reaction tubes and means for the electrical heating of the one or more reaction tubes. The reactor vessel has one or more discharge orifices which are permanently open or are set up to open above a preset pressure level, and gas feed means are provided, which are set up to feed an inerting gas into an interior of the reactor vessel.

The invention relates to a process for treating a waste lye of a lye scrub using an oxidation reactor (), the waste lye and oxygen or an oxygen-containing gas mixture being introduced into the oxidation reactor () and steam being introduced into the oxidation reactor (). It is provided that the steam is at least partially introduced by means of a steam feeding device (), which has a cylindrical section () with a centre axis () and a wall (), the centre axis () being aligned perpendicularly, a number of groups of openings () being formed in the wall, each of the groups comprising a number of the openings (), and the number of openings () of each of the groups being arranged in one or more planes () that is or are in each case aligned perpendicularly to the centre axis (). A corresponding installation and also a corresponding oxidation reactor () are likewise the subject of the present invention.

Process and device for treating a waste lye

In a process as disclosed according to the present invention, gases or gas mixtures used to form a reactant mixture in an at least temporarily ignitable composition are fed into a mixing chamber () through the passages () in a boundary wall () of the mixing chamber () and by means of one or more feed conduits () which have feed orifices () and extend into the mixing chamber (), respectively. The present invention likewise provides a corresponding reactor ().

Method for oligomerization of ethylene

The invention relates to a process for preparing linear &#x3b1;-olefins, wherein ethyleneis conducted into the oligomerization reactorin the liquid phase. The oligomerization reactorhas a mechanical stirrerin order to ensure optimal mixing of the liquid ethylene and of the catalyst in the liquid phase. From the top of the oligomerization reactor, vaporized ethylene is drawn off together with light &#x3b1;-olefins and a small proportion of the organic solvent. The gas mixture drawn off from the top of the reactoris condensed together with gaseous fresh ethyleneby means of heat exchangerand separator. The liquid phase drawn off from the separatoris conducted by means of circulation pumpas liquid ethylene inputback into the oligomerization reactor. The liquid products of the oligomerization reaction are drawn offlaterally from the base of the reactor

Process for preparing linear &#x3b1;-olefins

Valve arrangement for a system which is loaded with fluid, for connecting a first pressure region to a second pressure region by means of a first valve and a second valve connected in series. A third valve connects a region between the first valve and the second valves to a third pressure region. The first valve closes when a pressure which prevails on the side of the second pressure region is at least as high as a pressure which prevails on the side of the first pressure region. The first valve is coupled to the second valve so that the second valve closes when the first valve closes. The second valve is coupled to the third valve so that the third valve opens when the second valve closes.
