    摘要： A method of replenishing reactant-depleted cavitation medium within a cavitation chamber without re-pressurizing the entire cavitation system is provided, reactant depletion resulting from the cavitation process performed within the cavitation chamber. In addition to the cavitation chamber, the cavitation system includes a cavitation medium reservoir flexibly coupled to the chamber via a pair of conduits. The flexible couplings allow the relative positions of the cavitation chamber and the cavitation medium reservoir to be varied, thereby providing a means of either forcing the cavitation fluid to flow from the chamber and into the reservoir or from the reservoir and into the chamber. Such fluid flow causes mixing of the cavitation medium contained within the chamber and that contained within the reservoir, thus allowing replenishment of the source, e.g., reactant, within the chamber by mixing the cavitation fluid contained therein with non-depleted fluid contained within the reservoir. Additionally, inducing cavitation fluid mixing by altering the relative positions of the chamber and the reservoir can be used as an aid to degassing.

    摘要： Method and apparatus for measuring the surface tension of a liquid inside a vessel (2), reactor, or inside a section of flow-through process pipe that is pressurized above normal ambient pressure, up to but not limited, to 100 psig (7000 kPa), includes a pair of tubes (2,3) having a small and large orifice in a modular probe assembly that allows the probes to be positioned at selected and variable distances below the surface of the liquid. A high pressure source (4) provides an inert nitrogen or process gas through a pressure regulator (5) to the input of two or three mechanical or electronic mass flow controllers (6,7,8), powered by an external power supply (9), which control the bubble rate at each orifice through manual adjustments, or electronic set points determined by a computer software program, independent of the pressure in the vessel, reactor, or flow-through process pipe. One or more differential pressure transducers (10,11) measure the pressure of bubbles being formed and released from the two orifices. A transducer demodulator circuit (12) converts the resulting fluctuating pressure signal directly to an equivalent fluctuating electrical DC voltage signal. This signal is input to a (13) computer using one or more plug-in analog input/output computer interface circuit boards (14). A software program tracks the differential waveform and captures the maximum differential bubble pressure which is directly proportional to fluid surface tension. A temperature probe (15) and/or other commercially available probe (such as conductivity, viscosity, or density) is immersed at the same level as the orifices to measure liquid temperature, and/or other process parameters. A pneumatic damper (16) smoothes the large orifice signal in the single transducer apparatus (FIG. 1), whereas in a two transdcuer apparatus the average maximum values of the two individual, undampened, pressure signals are electronically substracted to provide the maximum differential bubble pressure which is directly proportional to fluid surface tension.

    摘要： Apparatus for measuring the surface tension of a liquid contained in a flow-through pressure vessel (60) includes a pair of tubes (50,51) having small and large orifices positioned below the surface of the liquid. A source (10) provides gas through a pressure regulator (15) and a flow regulator (30) to the tubes. The bubble rate from the orifices is controlled by needle valves (40,41) and is made independent of the pressure in the vessel by the flow regulator (30). Differential pressure transducer (70) measures the pressure in the tubes as an indication of surface tension. Check valves (72,73) protect the transducer, and a thermometer (65) measures liquid temperature.

    摘要： A cavitation system in which a source gas, e.g., a reactant, is loaded into the cavitation medium prior to cavitation is provided. The cavitation system includes a cavitation chamber with suitable cavitation drivers and a cavitation medium reservoir, the chamber and reservoir being flexibly coupled together via a pair of conduits. The conduits can be fabricated from a plastic or, as is preferred for higher temperature liquids, a metal. Typically metal conduits are formed into a coil, thus providing the desired flexibility. Flexibility is required in order to allow the relative positions of the cavitation chamber and the cavitation medium reservoir to be varied. The system is configured such that the cavitation fluid will flow out of the cavitation chamber, through the lower coupling conduit and into the cavitation medium reservoir when the chamber is positioned higher than the reservoir, and flow out of the cavitation medium reservoir, through the lower coupling conduit and into the cavitation chamber when the reservoir is positioned higher than the chamber. As a consequence of this configuration, cavitation fluid can be readily exchanged between the cavitation chamber and the cavitation medium reservoir, thereby aiding the degassing process as well as providing a means of replenishing reactant-depleted cavitation medium.

    摘要： The present invention provides an objective bubble point pressure determination method enables new applications of downhole PV (Pressure Volume) test results such as in situ measurement of the bubble point pressure for use as a quality control parameter for sampling. The present invention provides a method and apparatus to fit data points to a curve and to smooth these points over an interval of N points. The derivative of the curve is determined to obtain peak acceleration. The peak acceleration represents the bubble point pressure. This bubble point pressure is verified by comparison to changes in fluid compressibility and visual observation of a pressure volume plot history.
