A reactor and its internals used for the thermal processing of a mixture. The reactor comprises plates and at least part of the surface of said plates is used to perform said thermal processing. The reactor and its internals are used for the thermal processing of mixtures containing organic compounds. The processes, for thermal processing a mixture comprising organic compounds, comprising the steps of feeding the reactor and its internals and being useful for treating wastes oils and/or for destroying hazardous and/or toxic products; and/or for reusing waste products in an environmentally acceptable form and/or way, and/or for cleaning contaminated soils or beaches, and/or cleaning tar pits, and/or use in coal-oil co-processing, and/or recovering oil from oil spills, and/or PCB free transformed oils. A process for fabricating the reactor and its internals is also proposed.

A continuous acoustic chemical microreactor system is disclosed. The system includes a continuous process vessel (CPV) and an acoustic agitator coupled to the CPV and configured to agitate the CPV along an oscillation axis. The CPV includes a reactant inlet configured to receive one or more reactants into the CPV, an elongated tube coupled at a first end to the reactant inlet and configured to receive the reactants from the reactant inlet, and a product outlet coupled to a second end of the elongated tube and configured to discharge a product of a chemical reaction among the reactants from the CPV. The acoustic agitator is configured to agitate the CPV along the oscillation axis such that the inner surface of the elongated tube accelerates the one or more reactants in alternating upward and downward directions along the oscillation axis.

An apparatus for calcining gypsum includes a housing, at least one burner assembly, and at least one baffle. The housing has opposite first and second lateral walls, an inlet, and an outlet. The at least one burner assembly is connected to the housing, and can include a burner, a fluidization plenum, and a serpentine burner conduit. The serpentine burner conduit at least partly extends through the housing and to the fluidization plenum. The at least one baffle is disposed in the housing and attached to one of the first and second lateral walls. The baffle extends at least partly across the housing toward the other of the first and second lateral walls to define a flow path for the gypsum. The flow path extends from the inlet, around the baffle, and to the outlet.

An internal support system for a stirred tank reactor includes at least one plate securable to one or more axial positions within a vessel of the stirred tank reactor along an impeller axis. The at least one plate has an outer portion at least partially defining a primary opening and a plurality of peripheral openings radially spaced from the primary opening. The at least one plate may further include an inner portion positioned within the primary opening and fixed to the outer portion, the inner portion being disposable about the impeller axis and at least partially defining a central opening sized to receive a rotatable impeller shaft therethrough. Each opening of the plurality of peripheral openings may be coaxial with a different port of a headplate of the stirred tank reactor when the at least one plate is secured to the axial position within the vessel.

Disclosed herein is a rotary tube furnace configured to facilitate a chemical reaction between a solid mass and a gas in the furnace. The rotary tube furnace may comprise a reaction chamber extending through the furnace, the reaction chamber configured to control ingress and egress of each of the solid mass and the gas in the reaction chamber; a passage way configured to supply the solid mass to the reaction chamber; a passage way configured to supply the gas to the reaction chamber and circulate the gas through the reaction chamber; a heater providing heat to the reaction chamber and configured to control a reaction temperature in the reaction chamber; a magnetic field source in proximity to the reaction chamber for generating a magnetic field to one or more reaction zones of the reaction chamber; wherein the reaction chamber provides for mixing the solid mass and the gas.
