Supercritical water oxidation reactor with wall conduits for boundary flow control
First Claim
1. A reactor tube for supercritical water oxidation, comprising:
- a source of water, an elongate tube having a tube wall comprised of a laminate of platelets, each platelet less than about 0.100 inch in thickness and etched in a pattern such that the etched regions of all platelets overlap to form a plurality of flow passages communicating the exterior of said tube wall with the interior thereof, each said flow passage defining a direction of flow toward said interior and each said flow passage comprising;
a flow metering channel of substantially uniform cross section and elongate and unbranched in shape, the length and cross section of said flow metering channel selected to offer a preselected resistance to flow therethrough, said flow metering channel in fluid communication with said source of water, anda distribution section to receive water emerging from said flow metering channel and causing said water to flow in directions parallel to said tube wall, said distribution section having a cross section expanding in said direction of flow and terminating in an elongate exit port which is transverse relative to lift elongate tube and shaped to direct said water to flow in a sheet along the interior of said tube wall, said distribution section containing flow diverters to distribute said water substantially uniformly over the width of said elongate exit port,the elongate exit ports of all said flow passages being arranged to supply water along the interior of said tube wall in a substantially continuous film.

Abstract
A reactor tube for supercritical water oxidation is designed to supply a thin, continuous layer of water along the inner surface of the reaction zone by a wall lining formed of laminated platelets individually etched and superimposed to form an array of engineered fluid passages through the wall. Each passage includes a flow metering channel of closely controlled configuration to impose a preselected level of resistance to water flowing through it, plus a distribution section which distributes the water emerging from the flow metering channel over the length of a slot-shaped exit port. The exit port is arranged in conjunction with neighboring exit ports in an array over the inner surface of the reactor such that the emerging water forms a continuous film over the surface, thereby protecting the surface from corrosion and salts deposition from the supercritical reaction medium.
