Противоточный центробежный экстрактор

A continuous, completely jacketed countercurrent centrifugal extractor of the type utilized to mix and separate two liquids that have different specific gravities and enter through separate inlets. The extractor has at least one overflow weir in a mixing zone between the inlet for the specifically lighter and the inlet for the specifically heavier liquid phase and a division of the mixing zone into mixing-and-separation compartments. Access channels empty into the vicinity of the inner surface of a drum jacket and into that of the heavier phase, to conduct the lighter phase out of the compartment inside the hub of a conveyor worm into the initial mixing-and-separation compartment. One or more overflow channels also empty into the vicinity of the heavier phase, in the overflow weir to divert the lighter phase separated in the initial mixing-and-separation compartment into another and subsequent mixing-and-separation compartment. The design creates several highly efficient contact points in the vicinity of the mixing zone that enhance the extracting action.

METHOD OF SEPARATING A SUBSTANCE FROM A LIQUID BY MEANS OF A PARTICULATE MATERIAL

In connection with separation of a substance from a liquid by binding said substance to small particles, for instance solids, a body of liquid is kept in rotation together with the particles having a density lower than that of the liquid. Liquid from which said substance is to be separated is brought into contact with the particles in a way such that these are maintained suspended in the rotating liquid body.

CENTRIFUGAL EXTRACTION PROCESS

A process for extracting a component from liquids using dense phase gases or supercritical fluids (dense phase solvent). The process contacts a liquid and the dense phase solvent in a rotating mixer to dissolve a desired fraction into the dense phase solvent to form a loaded solvent. Furthermore, the mixer separates the loaded solvent from the remaining raffinate. Then the rotating mixer discharges the loaded solvent and raffinate. Decreasing pressure on the loaded solvent converts the loaded solvent into a gas and the desired fraction to liberate the desired fraction from the gas.

Water Extraction Using a Directional Solvent

Purified water can be obtained via a continuous or semi-continuous process by mixing a liquid composition (e.g., sea water or produced frac water) including water with a directional solvent to selectively dissolve water from the liquid composition into the directional solvent. The concentrated remainder of the liquid composition (e.g., brine) is removed, and the water is precipitated from the directional solvent and removed in a purified form.

Mineral oils, purifying.- In treating a liquid by successive intermixture with another liquid of different density and by successive discharge of the mixed liquids into a series of gravity separators a, a<1>, a<2> from which they are separately withdrawn, the successive intermixture of the liquids is obtained in and by pumps b, b<1>, b<2>.

Distillative recovery of aromatics with water addition in azeotropic proportions

A hydrocarbon mixture consisting of an aromatic and a non-aromatic component is subjected to a liquid-liquid extraction and/or an extractive distillation. A solvent is used which selectively dissolves the aromatic component so as to form an extract phase. The extract phase is introduced into a distillation column for separating the solvent and the aromatic component. The column is provided with trays and the extract phase is introduced into the column at about the middle thereof from where the solvent flows downwardly and the aromatic component flows upwardly. Sufficient water is introduced into the sump of the column to insure that the trays above the location at which the extract phase enters the column are filled with water during the separation. This improves the operation of the distillation column. An arrangement for carrying out the above process is also disclosed.
