摘要： The invention relates to a welding process for producing a component (10) by depositing multiple layers (100) of a metal material in layers, said layers lying one on top of the other. In said process, the base (10a) of the component (10) is placed in a liquid coolant (6) such that the coolant contacts the base (6), and a surface (10b) of the base (6) lies above the coolant level (3). A first layer (100) of the material is deposited onto the surface (10b) by welding the material to the surface (10b), and each subsequent layer (100) is deposited onto a temporary component surface (10bb) formed by the previously deposited layer (100) by welding the material to the temporary component surface (10bb), wherein the heat resulting from welding the material is absorbed by the coolant (6). The invention additionally relates to a device (1) for carrying out the method.

摘要： The invention relates to a process for treating a sulfide-containing waste lye from a lye scrub in which the waste lye and oxygen or an oxygen-containing gas mixture is fed to an oxidation reactor (10) and in the latter is subjected to a wet oxidation, steam being fed into the oxidation reactor (10). It is provided that an oxidation reactor (10) with a number of chambers (11-19), of which a first chamber (11) has a greater volume than a second chamber (12), is used, the waste lye and the oxygen or the oxygen-containing gas mixture being fed to the first chamber (11), fluid flowing out of the first chamber (11) being transferred into the second chamber (12), the steam quantity and/or steam temperature of the steam fed into the oxidation reactor (10) being controlled by a control device (TIC), and the steam fed into the oxidation reactor (10) being at least partially fed into the first chamber (11) and into the second chamber (12). A corresponding installation (100) and also a corresponding oxidation reactor (10) are likewise the subject of the invention.
