摘要： A mixture of a first liquid of one density and a second liquid of a different density and which is substantially insoluble in the first liquid is separated by flowing the mixture through a gravity settler tank where the mixture separates into a clear upper layer of the lighter liquid, a clear lower layer of the heavier liquid, and an intermediate layer of uncoalesced droplets of one of the liquids dispersed in a continuous phase of the other at the interface between the upper and lower layers. Clear liquid from the upper layer is withdrawn through an overflow, and clear liquid from the lower layer is withdrawn through an underflow. An impediment or baffle extends across the settler tank transversely to the direction of liquid flow, and is disposed in the intermediate layer of the mixture of the two liquids to impede the flow of the intermediate layer away from the tank inlet.

摘要： A countercurrent extraction column for carrying out a liquidliquid extraction of two phases which are insoluble in each other, where one of the phases is a conducting phase and the other of the phases is a non-conducting phase, by the use of simultaneous electrolysis. This extraction process is carried out in an upright column. A wall is provided within the column so as to separate the column into an anode compartment and a cathode compartment. An anode is provided within the anode compartment and a cathode within the cathode compartment. A communicating element is provided within the wall separating the two compartments so as to establish communication between the compartments. The communicating element is oriented so as to open into the compartment through which flows the non-conducting phase in such a manner as to face away from the direction of flow of the non-conducting phase.

摘要： Apparatus for performing a liquid-liquid extraction and electrolysis comprising a closed hollow container equipped with means for countercurrently contacting streams of liquid, means for creating turbulence in the liquid mixture, means for passing an electrical charge through the liquid mixture, and means for retarding the passage of liquid through the container. In one embodiment, the means for creating turbulence in the liquid mixture comprises a rotatable shaft with agitator blades mounted thereon and, in another embodiment, comprises a pulse wave generator. The apparatus is capable of carrying out a wide variety of liquid-liquid extractions and electrolysis reactions, but is particularly applicable to processes for changing the valence state of a metal of variable valence state to effect its separation from other metals and for concentrating metals of variable valence state in solution. In the process of the invention simultaneous valence change of a metal of variable valence state and concentration of that metal in aqueous solution is accomplished by passing a continuous stream of an aqueous solution through a column, passing a continuous stream of an organic solution of at least one metal of variable valence state which is preferentially soluble in the aqueous solution in its changed valence state countercurrently through the column, while maintaining the flow ratio of organic solution to aqueous solution greater than 1:1, forming a dispersion containing a continuous aqueous phase by creating turbulence in a zone where both the aqueous solution and the organic solution are present, allowing the dispersion to contact one electrode of an electrolytic cell which has its electrodes separated by a porous membrane, passing an electric current through the dispersion, and separating the immiscible organic and aqueous phases. This process is particularly useful to reduce hexavalent uranium to tetravalent uranium, to reduce tetravalent plutonium to trivalent plutonium, to concentrate these metals in solution in their changed valence states, and to separate plutonium from uranium.

摘要： The present disclosure relates to the technical field of chemical engineering, and specifically discloses a method for removing oxygenated compounds from a Fischer-Tropsch oil having a high carbon number. A reaction-extraction combined process is used in this method for removing oxygenated compounds from a Fischer-Tropsch oil having a high carbon number, wherein the Fischer-Tropsch oil (C5-C20) is firstly subjected to alkaline washing with an alkaline aqueous solution to convert acidic substances into water-soluble salts. The Fischer-Tropsch oil is subjected to a primary extraction with a carbonate-based extractant to remove alcohols and esters therein, and subsequently subjected to a secondary extraction with propylene carbonate to remove ketones and aldehydes impurities therein, thereby removing oxygenated compounds in the Fischer-Tropsch oil. After extraction, the content of the oxygenated compounds in the Fischer-Tropsch oil may be down to 1-60 ppm, and the yield of oil product may be kept 90% or more.

摘要： Systems and processes for removing and purifying bromide from an aqueous bromide solution are described. Electrochemistry is used to either convert bromide to bromine to allow its extraction in an organic phase, or to cause deposition of bromine onto an electrode. In either case, once removed from the aqueous bromide solution, the bromide can be recovered and purified.
