| 284 | Continuous Evaporative Concentration of Used Drilling Muds | US14504072 | 2014-10-01 | US20160096122A1 | 2016-04-07 | Kevin Smith; Alan Rossiter |
| Used water-in-oil emulsified drilling muds are prepared for reuse by removing excess water. The excess water is removed by passing the used mud through a cavitation device, under controlled conditions, along with injected air. While the emulsion is heated in the cavitation device, the air is finely dispersed in it, so is able to absorb water evaporated from the discrete, discontinuous phase aqueous droplets in the emulsion. A mixture of incoming and aerated emulsion is maintained at an optimal temperature in a process tank while a steady state continuous process is controlled to utilize the heat input, after compensating for radiant heat losses and other system losses, substantially exclusively for the evaporation of water in the emulsion. The process is applicable to any water-in-oil emulsion. | ||||||

| 293 | Method for processing gold-bearing sulfide ores involving preparation of a sulfide concentrate | US735783 | 1996-10-23 | US5837210A | 1998-11-17 | Gary L. Simmons; John C. Gathje |
| Provided is a method for processing a gold-bearing sulfide ore which involves maintaining the ore in a substantially oxygen free environment, preferably beginning with comminution of the ore and ending when a desired final concentrate, enriched in sulfide minerals, is obtained by flotation. In one embodiment, nitrogen gas is used to substantially prevent contact between the ore and air during comminution of the ore and during flotation operations. It is believed that oxygen gas present in air detrimentally affects the recovery of sulfide minerals in a flotation concentrate through surface oxidation of sulfide mineral particles. The use of a gas such as nitrogen can significantly reduce the potential for such surface oxidation. Additionally, gases separated from an oxygen plant may be beneficially used, with an oxygen gas stream being used, for example, for pressure oxidation of sulfide mineral materials, and with a nitrogen gas stream being used in comminution and/or flotation operations, resulting in advantageous use of a nitrogen gas by-product stream which has previously been vented to the atmosphere as waste. | ||||||

| An invention including an apparatus and process for generating small bubble foam using foam generating equipment in manufacturing processes such as benefication, flotation, flocculation, and for dust control in size reduction processes of a substrate, whereby a continuous, precise amount of a defactant is added to the treated substrate after introduction of the foam and processing of the substrate, in order to neutralize the residual small bubble foam so that the residual foam does not interfere in subsequent processes. | ||||||
| 295 | Fruit/vegetable floatation grading | US920017 | 1992-07-27 | US5305888A | 1994-04-26 | Donald M. Meylor; Patrick J. Finn |
| A floatation separation method is described for separating pieces of fruit or vegetable of the same type, but wherein desirable pieces have a slightly different specific gravity from the undesirable ones, and all have a specific gravity about the same as that of water. The pieces (12, FIG. 3 ) are placed near the surface of a body of water, and a cloud (40) of tiny air bubbles is maintained in the water. As the bubbles float to the surface they encounter the articles and slightly increase their buoyancy. The increase in buoyancy is slight and uniform, so those articles having a density slightly greater than that of the water will remain at the water surface, while those of a slightly greater density cannot be floated by the air bubbles and will sink to the bottom. The cloud of air bubbles is created by allowing air at about atmospheric pressure, to emerge from apertures in a rapidly spinning rotor that open in a direction primarily opposite to the spin direction. | ||||||

| A method of, and apparatus for, separating phases in a polyphase system is described and particularly in separating oil from produced water by the contact of gas bubbles and oil droplets by a dispersed gas flotation technique. A polyphase system is divided into at least two portions. The pressure of one portion is reduced to form bubbles of a gas, and the two portions are then recombined whereby the bubbles in the mixture enhances flotation, and hence separation of the dispensed phase, e.g. oil, from the continuous phase, e.g. water. The invention has particular application in the oil industry and in other fields where efficient separation is required. | ||||||
| 297 | Method of removing dissolved oil from produced water | US939865 | 1986-12-08 | US4752399A | 1988-06-21 | Carrol L. Viator; Glenn E. Gilley; Dennis Gracy |
| A process for removing dissolved and undissolved oil and chemical additives from waste and/or produced water streams involves contacting a first gas with the produced water stream, the first gas utilizing hydrogen bonding and dipole interactions with the contaminants to remove them from the water. The rise rate of the first gas is accelerated by mixing a second, more buoyant gas with the first gas. The first gas and second gas are recovered by the application of a vacuum to the waste stream after treatment. The first gas is separated from the second gas by compressing and cooling the combined gas stream, venting the majority of the second gas stream while the first gas is liquified, then expanding the first gas before returning it to the flotation vessel. The first and second gases are mixed with the contaminated water stream at line pressure so that mixing is intimate and flotation is accelerated. | ||||||
| 298 | Process for cleaning metal working fluids for re-use | US572341 | 1984-01-20 | US4492636A | 1985-01-08 | John M. Burke |
| Disclosed is a process for removing foreign matter and tramp oil from a continuously recirculating metal working fluid. The process includes the use of saturated dissolved air flotation which, contrary to prior belief, is able to effectively remove the foreign matter and tramp oil in a quiescent manner with little or no foaming and without removing or harming any emulsions present in the metal working fluid. The process further includes the use of water soluble organic cationic and anionic polyelectrolytes where desired to flocculate the foreign matter and tramp oil to enhance their removal from the metal working fluid and a process by which the formation of foam at or near the surface of the metal working fluid being clarified is able to be suppressed. | ||||||

| An elutriation apparatus which combines pressurized liquid jets and the low energy air bubble flotation for the separation is described. A manifolded set of multiple apparatus which increases operator efficiency is described. Quantitative separation of roots is achieved by the apparatus by a closed system of mechanical separations using water and air to isolate and deposit roots on a sieve submerged in the water. The method provides a rapid, quantitative and inexpensive method for measuring plant root responses to soil biological, chemical, and physical conditions. | ||||||

| Mineral impurities can be effectively removed from coal by introducing oil droplets into an aqueous slurry of pulverized coal. Coal, which is lipophilic, attaches to the surface of the oil droplets and floats upwardly along with the oil droplets utilizing their buoyancy. On the other hand, mineral impurities, which are hydrophilic, are left in the aqueous slurry. | ||||||
