Abstract:
A device for desalination of water having an inlet for saltwater, a first inner container arranged rotatable around an axis, a second container having an evaporation surface, a heater for heating of the second container and thereby also the evaporation surface, and a motor arranged to rotate the containers around the axis of rotation. The second container encloses the first inner container and is connected fixed to the first inner container. A mechanism for distributing water on the evaporation surface is constituted by holes arranged in the container wall of the first inner container so that water may pass out to the second container. Holes are also arranged in the container wall of the second container so that steam may pass out from the second container. A condensation surface is arranged for condensation of steam which passes out through the holes in the container of the second container.
Abstract:
The present embodiments provide a system and method for separation within a polymer production process. Specifically, a flashline heater configured according to present embodiments may provide more time than is required for complete vaporization of liquid hydrocarbons that are not entrained within a polymer fluff produced within a polymerization reactor. Such extra time may allow for liquid hydrocarbons that are entrained within the polymer fluff to be vaporized.
Abstract:
A process for recovering metal from a process material comprising the metal and a component that is more volatile than the metal, which process comprises: transporting the process material in a retort provided in a furnace, the retort being operated under vacuum and at a temperature sufficient to cause sublimation of the component from the process material thereby producing purified metal; depositing the component that has been sublimed on a cool surface; removing purified metal from the retort; and removing deposited component from the cool surface.
Abstract:
A grease removing device for removing liquid grease from solutions such as soups and broths and a method for using the device are disclosed. The grease removing device includes a flat plate having a multiplicity of projections on its undersurface. A container for holding coolant and a handle are also provided. In operation, the plate is cooled to a temperature lower than the freezing point of the grease; the undersurface of the plate is then brought into contact with the floating grease; and the plate with the attached solidified grease is then removed from the solution.
Abstract:
This invention relates to an apparatus and method for evaporative concentration of aqueous solutions and slurries which utilizes as the evaporative unit a wet-wall direct heat exchange evaporator. In a preferred embodiment, an open flame jet operates within a descending liquid vortex, radiant heat being transferred from the flame to the liquid on the walls of the evaporator, and the hot combustion gases being intermixed with the exiting liquid for sensible heat transfer. By special means and method steps scale formation is avoided and the solids are precipitated in filterable form. The apparatus and method are particularly adapted for the restorative processing of spent aqueous sulfuric acid pickling liquors which contain high concentrations of metal salts, including salts such as ferrous sulfate, which exhibit reverse solubility characteristics.
Abstract:
A groundwater remediation system includes a capillary media supported and positioned such that it is partially submerged into a groundwater source to be remediated. Groundwater is drawn into the submerged portion of the capillary media and further into the non-submerged portion of the capillary material via natural capillary action. As the water evaporates from the non-submerged portion of the capillary media, the dissolved solids within the water precipitate onto the media leaving the precipitated solids for reclamation or disposal and allowing the cleaned water vapor to disperse into the ambient air. In some embodiments, heat may be added to the media, water, or air to accelerate the evaporative process.
Abstract:
A supercritical extractor system may include extractor chambers coupled to a supercritical fluid pump and configured to receive a matrix for an extraction process and a supercritical fluid from the supercritical fluid pump, and evaporator chambers coupled to the extractor chambers and configured to output an extractant from the matrix. Each evaporator chamber may include a body defining a cavity, a cone within the cavity, and arms coupled between an inner surface of the body and the cone. The supercritical extractor system may include a condenser coupled between the evaporator chambers and the supercritical fluid reservoir, and a controller coupled to the supercritical fluid pump, the extractor chambers, and the evaporator chambers and configured to monitor a characteristic during the extraction process.
Abstract:
A process for production of minerals using an evaporation unit comprising an evaporation element for exposing thereof to the atmosphere for evaporation of a liquid solution therefrom. The evaporation element comprises an evaporation surface and a texture for deflecting the solution during movement along the surface, leaving minerals on the surface as a result of evaporation of the solution. The texture allows the minerals to detach from the element under the sole influence of normal forces of nature before the minerals reach a weight capable of damaging the evaporation unit. The process includes wetting the element with the solution, which at least partially evaporates and forms precipitated minerals, at least some of which are left on the surface; and letting the minerals detach from the surface solely under the influence of normal forces of nature before the minerals on the surface reach a weight capable of damaging the unit.
Abstract:
A pond for cooling and/or recovering salt from a hot aqueous solution of a salt such as potassium chloride produced by solution mining. The pond comprises a plurality of channels arranged side-by-side, each of the channels being defined by a plurality of sides. An inlet is provided in a side of a channel for receiving the aqueous solution, and an outlet is provided in a side of another one of the channels for discharging the aqueous solution. The pond has at least one dike separating the channels from one another. A gap is formed in each dike to permit the aqueous solution to flow between the channels, the gap having a length which is about 10 to about 40 percent of the length of the sides of the channels. Salt is crystallized and the solution is cooled as it passes through the channels of the pond.
