A device for the thermal treatment of material comprises a housing having a heatable housing jacket, which surrounds a treatment chamber and forms a rotationally symmetrical treatment surface extending in an axial direction, and a drivable rotor, which is arranged in the treatment chamber and extends coaxially. The rotor comprises a shaft, arranged in a manner distributed over the circumference of which are spreading elements. The device also comprises a condensation space, in which a condenser is formed and into which gaseous material components escaping from the material during the thermal treatment can pass, a condensate outlet for discharging the material components condensed in the condensation space, and a vacuum connection, which is fluidically connected to the condensation space. The vacuum connection is arranged in a region of the housing that lies downstream of the treatment surface, as viewed in the transport direction of the material.

A rotary evaporator for evaporating a substance contained in an initial substance comprises an evaporation flask (2) for receiving the initial substance, a device (3) for heating the substance, a condenser (4) for condensing the vaporized substance, a collection container (6) for receiving the re-liquefied substance and at least one device (5) for generating a low pressure and/or an excess pressure. In order to remove the re-liquefied substance an excess pressure can be generated at least within the collection container (6) and/or in order to remove residues of the initial substance an excess pressure can be generated at least within the evaporation flask (2).

The present invention provides a rotary evaporator capable of accurately quantifying concentrated liquid and/or distillate. A distillation flask is improved into a structure having a liquid discharge opening formed at the bottom, and/or a spherical collecting flask is improved into a structure having a liquid release opening formed at the bottom. Concentrated liquid and/or distillate can be discharged without dismounting the distillation flask and/or the collecting flask. In addition, fine metering scale tubes and quantitative capacity increase units are disposed at the liquid discharge opening and/or the liquid release opening, there is a valve on the top and another valve on the bottom of each tube, so that the constant subtle changes of the amount of concentrated liquid and/or distillate can be observed, and an accurate amount of concentrated liquid and/or distillate can be discharged.

Provided herein are integrated distillation apparatuses configured as stand-alone fully integrated systems having a reduced footprint. Integrated distillation apparatuses can have a rotary evaporator, a condenser, and an integrated refrigeration system or chiller, as well as an integrated water bath and vacuum pump, all of which can be integrated into a central frame and/or housing assembly. Integrated distillation apparatuses can be configured such that the rotary evaporator is movably attached to a frame structure and configured to be vertically translatable in position, whereas the condenser can be affixed to the structure by an arm extending from the structure and adjacent to the rotary evaporator, and wherein the refrigeration system can be in fluid communication with the condenser.

Herein, a cleaning device for a rotary evaporator (2) is provided. The rotary evaporator (2) comprises at least a rotatably arranged rotary flask (4) for receiving a substance to be evaporated and a condenser (5) for condensing the evaporated substance during operation of the rotary evaporator (2). The cleaning device (1) comprises at least a supply line (16, 16′) for supplying a cleaning agent, a cleaning agent supply (13) for storing the cleaning agent and a pressure generating means (15) for generating a pressure in the cleaning agent in order to supply a pressurized cleaning agent from the cleaning agent supply (13) through the supply line (16, 16′) to the rotary flask (4) and/or to the condenser (5).

A catalyst-free electrochemical deuteration method using deuterium oxide as a deuterium source, adding an electrolyte, an organic compound containing an ethylenic bond or acetylenic bond, deuterium oxide, and an organic solvent into a reactor, applying a direct current voltage of 4-8 V between electrodes of a carbon felt in an atmosphere of an inert gas for an electrolytic reaction, to obtain a product, and purifying the product to obtain a deuterated product. In the method provided by the present disclosure, with the organic compound containing an ethylenic bond or acetylenic bond as a raw material, deuterium oxide as a deuterium source, cheap and readily available carbon electrode materials as cathodes and anodes, it is possible to obtain deuterated products by a direct current electrolysis in an organic solvent, without any transition metal catalysts.

A system and method for decontaminating a fluid and recovered vapor, particularly processing and recycling water used in an oil zone steam process, utilizing a vaporizer-desalination unit to separate a contaminated water flow into a contaminated disposal flow and a clean water vapor flow. The contaminated water flow is recovered after separation from a combined oil and water flow from an oil well. The clean water vapor flow is preferably passed through a steam generator to produce the steam used in the oil zone steam process. The steam is injected into the oil zone of a designated well and then extracted as the combined oil and water flow. Once primed with sufficient external water, the system and method is designed to operate continuously with minimal replenishment because of the water/vapor/steam cycle.
