TLDR
In this paper, the supercritical zone is enclosed by a subcritical jacket stream formed from cooling water, and the reaction is carried out in the form of a flame (5).Abstract:
In the process according to the invention for the purification of salt-laden waste water by wet oxidation of organic constituents at supercritical conditions, the reaction is carried out in the form of a flame (5). The supercritical zone is enclosed by a subcritical jacket stream (4) formed from cooling water. At one end of the reactor (1) designed as a cylindrical pressure vessel at least one burner nozzle (2) and at least one annular cooling water feed position (48) surrounding the burner nozzle are provided; at the other end, at least one collective exit position (160) for cooling water, reaction products and, in particular, precipitated salts are arranged. Because of the jacket stream, there are no blockages due to salts; corrosion problems are substantially neutralised.read more

Supercritical oxidation system using a cooled-wall shell
Cocero Alonso Maria Jose,Gonzalez Calvo Rafael,Fernandez-Polanco Fernando,Soria Garcia Jose Luis +3 more
TL;DR: In this article, a supercritical oxidation system using a cooled-wall shell is described, where the shell is cooled either by its own feed from the system or by a fluid external to the process, and therefore requires less thickness, the cooling in both cases having a pressure similar to that of the oxidation process.

Method for solids separation in a wet oxidation type process
TL;DR: In this paper, a two-zone pressure vessel is proposed for aqueous phase oxidizer and solids separator, in which precipitates and other solids fall or are sprayed from a supercritical temperature super zone into a lower temperature sub zone.
