ABSTRACT:
The heat exchanger, which forms a part of the fluid treatment apparatus of this invention, includes an insulated tubular having concentric telescopically nested spaced tubes, wherein the space between the tubes is sealed and filled with an inert gas. The surfaces of the tubes are coated with a hydrogen permeation barrier preferably comprising an aluminum-iron alloy, nickel or copper which limits atomic hydrogen permeation into the space between the tubes, which would combine to form hydrogen gas and result in heat loss. The insulated tubular is telescopically nested in a pipe, forming a fluid heat exchanger and the heat exchanger is telescopically nested in fluid waste circulation pipes, forming the fluid treatment apparatus of this invention. The preferred fluid heat exchanger is a vertically extending deep well reactor suitable for wet oxidation reaction of fluid wastes including municipal sludge.
