Abstract: A reactor system for thermally treating a hydrocarbon-containing stream, that includes a pressure containment vessel comprising an interior chamber and a heat transfer medium that converts electrical current to heat and is positioned within the interior chamber of the pressure containment vessel, wherein the heat transfer medium comprises a first end face, a second end face, and channels extending between the first end face and the second end face. A process for thermally treating a hydrocarbon-containing stream includes introducing the hydrocarbon-containing stream into the reactor system, pressurizing the pressure containment vessel and the heat transfer medium without heating the pressure containment vessel or the heat transfer medium, supplying electrical current to the heat transfer medium, converting the electrical current to heat, heating the hydrocarbon-containing stream, and converting the hydrocarbon-containing stream to an effluent stream.

Abstract: The present invention relates to a method and an arrangement for pressure and temperature let down of autoclave discharge slurry, in particular in pressure oxidation or high pressure acid leach of metal containing ore. The method of the invention comprises a step of providing autoclave vent gas obtained from the autoclave to the top-entry flash vessel for inducing overpressure to the top-entry flash vessel and preventing boiling of the slurry during the transfer to next top-entry flash vessel. The invention further relates to an autoclave and pressure let-down arrangement adapted for providing autoclave vent gas to one or more top-entry flash vessels.

Abstract: An autoclave suitable for use for heating articles such as tires is described. The autoclave includes an elongated chamber having an interior section and an annular duct surrounding the interior section, wherein the annular duct is separated from the interior section by a dividing wall; said autoclave further including a heat source for heating the air, a fan for circulating the air in the chamber, and an air deflector mounted in a distal end of the chamber. The air deflector is positioned to redirect the airflow towards the interior portion of the chamber to eliminate air recirculation zones and improve the temperature uniformity.

Abstract: Disclosed are a hydrogen generator and a method of producing hydrogen gas therefrom. A fuel unit containing a fuel that releases hydrogen gas when heated is removably disposed in a cavity within a housing having a door. A heater assembly for heating the fuel unit is disposed in the hydrogen generator. A mechanism retracts the heater assembly from the fuel unit when the door is opened and extends the heater assembly to contact the fuel unit when the door is closed. When the heater assembly is retracted, more space is available into which the fuel unit can be inserted to prevent damage to the heater assembly and the fuel unit, and when the heater assembly is extended, good contact is provided between the heater assembly and the fuel unit for efficient heating. A cam bar can move the heater assembly normal to the lateral motion of the cam bar.
