The invention relates to a method and a device for cleaning contaminated used oil, in which starting material is heated to the gas phase and the resultant vapor is rectified, with purified oil being removed as condensate from a drain in a rectification column. This enables efficient operation even in the smallest of systems, such that a compact system configuration and thus in particular mobile use by a container structure is made possible. The invention also reduces the cost required for servicing. The used oil is subjected to an evaporation process by at least indirectly placing the starting material in contact with a melting bath, the melting temperature of which is above the evaporation temperature but below the ignition temperature of the used oil, and by rectifying the vapor in the rectification column.

A produced water evaporation system for spray evaporating water comprising a geothermal heat retainment system and an evaporation system is disclosed. The geothermal heat retainment system comprises a first feed inlet, an optional solar collection system or a heat exchanger, and a first discharge outlet. The evaporation system comprises a second feed inlet, a pump, a drip manifold comprising a drip orifice or a manifold comprising a nozzle, a container, wherein a first portion of a ceiling of the container is constituted by a demister element such that the first portion of the ceiling is entirely configured as an outlet for evaporated water and wherein a second portion of the ceiling is adjacent to an upper edge of a wall of the container, a second discharge outlet, and an air system comprising an air blower and an optional air preheater, wherein the air system is disposed through the wall of the container and wherein the air system discharges air flow counter to the produced water and/or water droplets from the drip orifice. A method of using the produced water evaporation system is also disclosed.

A MEG reclamation process includes the step of increasing above 2,000 ppm the divalent metal salts concentration of a rich (wet) MEG feed stream flowing into a precipitator. The increasing step includes routing a salts-saturated MEG slipstream from the flash separator it to the precipitator. The slipstream may be mixed with a fresh water feed stream, a portion of the rich MEG feed stream, or some combination of the two. The rich MEG feed stream also may be split into two streams, with a portion of the stream being heated and routed to the flash separator and the other portion being combined as above with the removed slipstream. The process can be performed on the slipstream after dilution and prior to entering the precipitator or after being loaded into the precipitator. Removal of the insoluble salts may be done in either a batch or continuous mode.

The invention is a high-salt waste water air powered low temperature evaporating device and method of use. A tray is mounted on a lifting platform; an air inlet and a water inlet are on the tray. Air distributing pipes are arranged at the center of the nested column tubes (33). A groove (4) is installed at the top of the tray, and mounting points are accompanied by multiple nested column tubes (33). The nested column tubes (33) are connected with the air inlet. An atomizer is arranged inside the air distributing pipes; and the atomizer is connected with the water distributing pipes. Using air power evaporates concentrated waste water multiple times so that the salt in the wastewater reaches saturated concentration, and therefore, the wastewater temperature is reduced, salt is crystallized and separated out, liquid is continuously evaporated, and the wastewater can be completely treated.

This application is for a device and article of manufacture for the purpose of drinking, tasting, sampling, and nosing and evaluating alcohol beverages without alcohol nose burn and numbing; a procedure or method to manipulate said vapors for the same purpose; and a process to separate and dissipate ethanol vapors to accomplish the same purpose. The device is one embodiment of a vessel which collects vapors in a chamber with curved sides and large surface area to promote evaporation, which chamber's top opening orifice concentrates same vapors prior to passing into an expansion chamber releasing and dissipating fast moving ethanol prior to nosing, providing improved aroma detection and enhancing nosing, tasting, and sampling experiences for all spirits, wines and liqueurs, distilled, fermented, and fortified.
