  • Fibrous media utilizing temperature gradient and methods of use thereof
    Patent number: 7147694
    Abstract: A method for removing a liquid from a gas, comprises passing the gas and the liquid through a network of fibers containing at least one fiber in which a temperature gradient has been induced along at least a portion of the length of the fiber, thereby permitting droplets of the liquid to be captured by the at least one fiber, and wherein the temperature gradient causes migration of the droplets. A method of preventing the fouling of a coalescence filter is also disclosed. The method comprises inducing a temperature gradient along at least a portion of a length of at least one fiber within the filter, wherein the temperature gradient causes migration of liquid droplets captured by the fiber. A coalescence filter medium comprising at least one fiber in which a temperature gradient has been induced along at least a portion of the length of the fiber is also provided.
