Abstract: 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.

Abstract: A three phase centrifugal separator for separating the components of a fluid mixture of oil, water and gas, consisting of a cylindrical drum rotatably mounted within a pressure vessel. Two liquid phase holding tanks connected to the pressure vessel are also maintained under pressure. The drum has an initial separation chamber which separates gaseous phase fluids from liquid phase fluids. Water is forced to the outer circumference of the drum by centrifugal force and forms a water zone within the confines of a first and a second annular weirs. The first annular weir is lower than the second annular weir such that water is retained in the water zone until the level of the first annular weir is attached, thereafter any additional water entering the water zone results in a migration of water between the drum and the first annular weir to a water phase outlet. Oil is forced into a water/oil interface on top of the water zone by centrifugal force.

The apparatus further provides for measuring the pressure of the exiting degassed liquid, the pressure measurement being used to regulate the flow of liquid into the bowl so as to maintain a substantially constant level of liquid therein.

Abstract: A multi-stage rotary inertial device and method in which rotary inertial thermodynamic impedance is used in the separation of materials according to their diferences in mass. Thus, an input flow composed of substances having two different masses is separated into two output flows having preferred concentrations, respectively, according to their different masses. Rotary inertial thermodynamic pumping is used for operation of intermediate separator stages. This can be controlled from outside the rotating device by selectively supplying heat to the rotating device.

Abstract: In connection with reduction of the pressure of newly produced oil, i.e. a mixture of hydrocarbon compounds, this conventionally is performed stepwise, a momentary pressure drop occurring at each stage.According to the invention it is suggested that oil is caused to flow radially inward in a chamber (12), which is formed by a rotating vessel (1) and which is only partly filled with rotating oil, whereby the pressure drop in the oil can occur relatively slowly. A free liquid surface is maintained in the chamber (12), and a certain gas pressure is maintained in the liquid free part thereof, while evaporated hydrocarbon compounds are removed through a central gas outlet (18).

Abstract: A fuel cell power system for use in a weightless environment, such as in space, includes a device for removing water from a water-hydrogen mixture condensed from the exhaust from the fuel cell power section of the system. Water is removed from the mixture in a centrifugal separator, and is fed into a holding, pressure operated water discharge valve via a Pitot tube. Entrained nondissolved hydrogen is removed from the Pitot tube by a bleed orifice in the Pitot tube before the water reaches the water discharge valve. Water discharged from the valve thus has a substantially reduced hydrogen content.

Liquid is supplied to the receiving chamber in such a way that a continuous liquid phase is maintained between the mixture in the supply conduit and in the receiving chamber.
