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

A device for introducing fluid medium into a container, the device including a container for receiving the medium and a pipeline for introducing the medium into the interior of the container. The pipeline has a pipeline section arranged in the interior of the container having a hollow cylindrical casing that extends along a cylinder axis of the pipeline section. The casing has an opening on a lower face that faces downward for introducing the fluid medium into the interior of the container. The opening includes two first edge portions extending along the cylinder axis and two opposing arc-shaped second edge portions that connect the two first edge portions to each other. A plate-shaped impact element is fixed to the casing and arranged below the opening so that the fluid medium that flows out of the opening strikes the impact element.

Device for introducing a fluid medium into a container

The invention relates to a distribution system () for distributing a fluid () into a container () from a fluid inlet () of the container (). Distribution system () comprises one or more guide plates that form a guide section () and a distribution section () that adjoins the guide section (). Distribution section () has regions () with openings () for allowing fluid () to pass through. The invention also relates to a heat exchanger device () that has a container () with a fluid inlet (), with at least one heat exchanger block () that is arranged in the container (). A distribution system () according to the invention is arranged in the container () above the heat exchanger block ().

The invention relates to a process for separating off solid particles, in particular coke particles, from a water phase by means of gravity in a plant for generating hydrocarbons by cracking a hydrocarbonaceous feed, and also to a device for carrying out the process. In contrast to the prior art, the water phase is taken off predominantly from a point above the column bottom B via the outlet A. The first gravity separatorwhich is constructed as a multistage settling tankis situated not beneath, but next to, the scrubbing water column. The bottom phase of the scrubbing water columnalready acts as a part of the first gravity separator. Thus, via the outletin the column bottom B, a heavy water phase which is loaded with coke particles is already taken off and passed into the second gravity separator. This heavy water phase is further treated, together with the heavy water phase which is loaded with coke particles from the recessesof the multistage settling tank. In this embodiment of the invention, the feed rate into the multistage settling tankneed not be controlled as in the prior art. The multistage settling tankand the bottom phase of the quench columnform a communicating liquid system in which the same level of the water phase is established.
