摘要： Apparatus and method for separating oil from water in produced oil without requiring large separation tanks in which the fluid is heated, using a simple, energy efficient separation process, are described. Centrifugal forces, by themselves, are not effective for completely separating a two-component fluid, especially when the densities of the fluids are similar, such as for heavy oil. By combining both primary and secondary acoustic forces, and taking advantage of centrifugal forces from fluid flow, such that acoustic radiation forces initiate the process of droplet accumulation, and contribute to droplet coalescence, centrifugal separation is enhanced.

摘要： Methods forth chemical dissolution of human and other cadavers, such as pets as an example, using ethanolic potassium hydroxide (KOH) or ethanol-water solutions of KOH at atmospheric pressure are described. After acid neutralization, to a neutral pH range, the resulting solutions may be applied to the earth for disposal as fertilizer, or further treated using hydrogen peroxide. Use of ethanol has been found to reduce the dissolution time of the cadavers to approximately two hours for high concentrations of KOH.

摘要： Apparatus (10) and methods for making simultaneous measurements of composition (water-cut), fluid flow, and sound attenuation in a multiphase fluid flowing (15) through a pipe (12) in real-time, using the same apparatus (10) are described. Additionally, the apparatus (10) provides real-time pipe wall thickness monitoring for observing pipe corrosion or internal deposition. Knowledge of wall thickness is necessary to correct for water-cut (oil-water composition) automatically by adjusting the liquid path length internal to the pipe (spool). The use of short duration frequency chirp excitation signals (24) enables the apparatus to provide information that can be used to extract multiple levels of information from the same measurement in multiphase fluids including the presence of a significant quantity of gas (~ 60% gas volume fraction) in different flow regimes. Besides measuring steady flow, this device is useful for measurements during fast changing flows, such as for a rod-pumped well. Measurements up to about 1000 times a second can reliably be made.

摘要： Apparatus (10) and methods for measurement of pore pressure in rock formations through a metal borehole casing (32) after a well is cased and cemented, are described. Such measurements may be accomplished by using the Dynamic Acoustic Elasticity (DAE) method for characterizing nonlinear parameters by perturbing a selected rock formation region with a High Amplitude, Low Frequency (HALF) acoustic strain wave, and probing this region using a Low Amplitude, High Frequency (LAHF) acoustic wave (18), (22). Time reversal techniques (36) may be employed for focusing acoustic energy into the formation in the vicinity of the pipe or open hole. The change in wave speed of the probe pulses as the HALF induced strain wave oscillation propagates through the formation, as a function of the induced strain, may be used to determine the nonlinear elastic parameters α, β, δ, and A of the pore pressure, from which the pore pressure may be determined in the region of the HALF wave.

摘要： Methods for noninvasive determination of acoustical properties of fluids flowing in pipes having a large ratio (> 10) of pipe diameter to wall thickness, and in highly attenuating fluids are described. When vibrations are excited on the outer surface of the wall of a pipe, the resulting vibrations propagate directly through the wall in a normal direction and through the pipe wail as guided waves, appearing on the opposite side of the pipe, in the oil/gas industry, where a majority of the pipes used for exploration are 2-in. diameter steel pipes, the time of arrival of the signals through these two paths are almost identical. Additionally, if the pipe is filled with various types of crude oil or crude oil/water mixtures, the acoustic attenuation increases significantly and the signals travelling through the two paths become similar in strength. This dual path propagation through pipes, where guided waves take the circumferential path in the wall of the pipe and may interfere with the time-of-flight measurement obtained from the direct path through the fluid, is at least in part resolved by subtracting the signal from the guided wave from the combined signal, thereby permitting improved observation of the direct path propagation through the fluid.

摘要： An apparatus for storing, warming and manually individually dispensing elongated cylindrical vials having different contents, while minimizing error and clutter, is described. Vials are stored in bins, which have manually operated dispensing members. Each bin may be separately heated using small incandescent bulbs or other heating elements. Adjustable temperature sensors may be placed in each bin to permit separate temperature control, and provide a high-temperature cutoff. One embodiment of the apparatus may be wall mounted to relieve congestion on horizontal surfaces. Another embodiment is suitable for table use, and has a reduced profile for clutter reduction.

摘要： An apparatus and method for the separation of an oil-water mixture into its components are described. An acoustic radiation force moves oil droplets to the nodes of an acoustic standing wave generated in a vertical column containing the oil-water mixture. Once the droplets are sufficiently close together, attractive forces become dominant and the droplets may coalesce to form larger droplets, which have greater buoyancy, and separation of the mixture into a layer of oil and a layer of water occurs, not possible by simple gravitational separation. Acoustically-driven oil-water separation may be used for water-cut measurements in oil production wells, since separation of the oil from the water permits accurate sound speed measurements to be made for both the oil and the water, thereby allowing frequent in situ calibrations of the apparatus to determine whether sound speed measurements on the mixture are accurate in the event that one or both of the mixture constituents is changing.
摘要翻译：描述了用于将油水混合物分离成其组分的装置和方法。声辐射力将油滴移动到在含有油 - 水混合物的垂直柱中产生的声驻波的节点。一旦液滴充分靠近在一起，吸引力将变得占主导地位，并且液滴可以聚结形成更大的液滴，其具有更大的浮力，并且混合物分离成一层油和一层水，不可能通过简单的重力分离。声学驱动的油水分离可用于生产油井中的水分测量，因为油与水的分离允许对油和水进行精确的声速测量，从而允许频繁的原位校准以确定混合物中的一个或两个混合物组分正在改变的情况下混合物上的声速测量是否准确。

摘要： A method for determining the total organic carbon in a sample (22) which includes mixing the sample with a reagent (32) containing at least one acid effective for reacting with inorganic carbon-containing materials in the sample, and at least one oxidizing agent effective for oxidizing organic carbon-containing materials in the sample in the presence of ultraviolet radiation, and detecting the carbon dioxide generated, is described. The at least one acid may include phosphoric acid, while the oxidizing agent may include sodium persulfate. The sample is first injected into a reaction chamber (16), which is continuously flushed with carbon dioxide free gas with no UV light present, and CO2 generated from any inorganic carbon in the sample as carbonates is flowed through the detector, and may be recorded. Subsequent to this step, UV light is passed through the reaction chamber and CO2 generated from the reaction of the at least one oxidizing agent with the organic material in the solution in the presence of ultraviolet radiation, is flowed through the detector (20), after the reaction chamber is sparged using a carbon dioxide free gas, and recorded.

摘要： The use of the electride form of 12CaO-7Al 2 O 3 , or C12A7, as a low work function electron emitter in a hollow cathode discharge apparatus (10) is described. No heater is required to initiate operation of the present cathode (12), as is necessary for traditional hollow cathode devices. Because C12A7 has a fully oxidized lattice structure, exposure to oxygen does not degrade the electride. The electride was surrounded by a graphite liner (18) since it was found that the C12A7 electride converts to it's eutectic (CA+C3A) form when heated (through natural hollow cathode operation) in a metal tube.
