摘要： A method for removing a surface foulant is disclosed. An operating heat exchanger is provided. A carrier liquid that contains potential fouling agents is provided to the heat exchanger. The potential fouling agents foul at least a portion of the heat exchanger. The exchanger is operated such that the carrier liquid is at a vapor pressure equal to the operating pressure. Cavitation inducing devices are provided to the exchanger. A condition indicating fouling is detected. The cavitation inducing devices are operated on a portion of the exchanger to cause a localized pressure change, vaporizing a portion of the carrier liquid and forming a transient bubble or bubbles which collapse by cavitation, producing a localized shockwave, a re-entrant microjet, and extreme transient pressures and temperatures. These steps are repeated as necessary to remove the surface foulant. In this manner, the surface foulant is removed from the operating heat exchanger.

摘要： An apparatus and method for measuring the level of a liquid. The apparatus includes an elongated probe comprising an electrically and thermally conductive material. The probe has an upper region to be disposed above the surface of the liquid, a lower region to be disposed below the surface of the liquid, and a middle region. A heater adds heat to the probe, and temperature sensors may measure the temperature of the probe in the upper and lower regions. Electrical circuitry may be used to control and receive signals from the various components and to measure the electrical resistance between a location in the upper region of the probe and a location in the lower region of the probe. The liquid level may be computed as a function of the measured values, the probe dimensions, and the known temperature dependence of the electrical resistance of the probe.

摘要： A device and a method for contacting gases and liquids in the presence of entrained solids is disclosed. A vertical, cylindrical vessel of a first diameter with a bubbling apparatus is provided comprising an outer apparatus diameter, surrounded by an annular space, a height above the bottom of the vessel. The outer apparatus diameter is between ⅓ and ¾ of the first diameter. The height is less than ½ of the difference between the first diameter and the outer apparatus diameter. The carrier gas bubbles upward out of the bubbling apparatus. A fluid passing through the vessel transitions from turbulent, to laminar or transitional, back to turbulent flow due to the changes in flow path areas.
