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.
