    摘要： A method and apparatus for analyzing a deposited layer on the inner surface of a fluid container wall having inner and outer surfaces are disclosed. One embodiment of the method comprises (a) transmitting an acoustic signal from a transmitter at a first distance from the outer surface of the wall; (b) receiving a first received signal A, comprising a reflection from the wall outer surface; (c) receiving a second received signal B, comprising a reflection from the wall inner surface; (d) receiving a third received signal C from the wall inner surface; (e) calculating a coefficient Rwp from A, B and C, and (f) calculating a coefficient Rpd from A, B and Rwp, and calculating the acoustic impedance of the deposited layer Zd from Rwp, Rpd, and Zw, where Zw is the acoustic impedance of the material between the transmitter and the wall outer surface. A preferred embodiment of the apparatus comprises a piezoelectric or ferroelectric transducer having front and back faces; a backing member acoustically coupled to said transducer back face and impedance-matched to said transducer element, said backing member having proximal and remote faces; and a delay material disposed between said transducer front face and the wall outer surface.

    摘要： An apparatus and method are provided for preventing or reducing buildup of certain solids in a system or a conduit containing or conveying a fluid. The fluid can be a single phase liquid, such as a liquid hydrocarbon, or a multiphase fluid such as a mixture of several immiscible liquids, for example liquid hydrocarbon and water, plus a gaseous phase that may include hydrocarbon vapors as well as other gases, for example carbon dioxide, hydrogen sulfide, etc. Preferably, the fluid is crude oil. The solids include all solids precipitating from fluids due to thermodynamically or chemical composition driven forces, as well as materials that can change phases. Preferably, the solids are solids typically dissolved in crude oil, such as higher paraffins, asphaltenes, hydrates, organic salts, and inorganic salts. The method involves passing the fluid through a treatment apparatus placed before the system or conduit under conditions sufficient to deposit the solids within the apparatus, slurrying the solids, and passing the resulting slurry to the system or conduit. The apparatus includes a passage having a length sufficient to effect substantially complete deposition of the solids.
