    摘要: In a method of separating carbon dioxide from a gas mixture, a liquid solvent flows down an array of vertical wires with the gas mixture flowing over the liquid. Once on the wire, the liquid quickly breaks up into drops of varying sizes, with each size moving down the wire at a different velocity. Large, faster moving drops overtake the small, slower moving drops to form even larger drops. As the drops fall, new drops are created behind the falling drops. Consequently, drops of a large range of sizes are forming, colliding, and mixing as they travel down the wire. During this process, gas molecules that have adsorbed onto the liquid surface are mixed into the interior of the solvent, resulting in highly effective mass transfer and gas absorption. This enhanced mass transfer allows greater flexibility in the choice of solvent and in the system design.

    摘要: The invention provides a device useful for measuring water temperature at a certain depth. The device includes a temperature sensing part embedded in an insulating matrix part which provides a useful heat flow pattern. After being exposed to water of a certain temperature the temperature sensing part wil thermally equilibrate to that temperature after a period of time. The device will then hold this temperature reading even while being briefly exposed to mediums of different temperatures, such as exposing the device to air or water of varying temperature, and will allow accurate readings of the original temperature. The device appears to exploit the difference in thermal conductivities of air versus other media, such as water or slurries.
