  • Patent number: 9005340
    Abstract: A fiber bed assembly used to remove aerosols and/or wetted soluble solids from a moving gas stream includes a fiber bed support and a fiber bed supported by the fiber bed support so that the gas stream passes through the fiber bed moving from an upstream space to a downstream space with respect to the fiber bed. A re-entrainment control device is located within a downstream space defined by the fiber bed so that at least a portion of the gas stream passes through the re-entrainment control device. The re-entrainment control device is shaped to change the direction of the average flow path of the gas stream as the gas stream passes through the re-entrainment control device so as to cause aerosols and/or wettable solids contained therein to be separated from the gas stream by inertial force. A re-entrainment control device and method of use are also disclosed.

  • Patent number: 7758665
    Abstract: A fiber bed mist eliminator has a fiber bed which is formed of a composite fiber bed collecting media strip including a collection layer which is not subjected to needle punching. The fiber bed can be made very thin while retaining high efficiency in removing small particles of aerosol from a gas stream passing through the fiber bed. The fiber bed collecting media strip lends itself to be applied to the mist eliminator by spirally wrapping the element onto the mist eliminator. The fiber bed collecting media strip can overlap itself to seal at the locations where the fiber element overlaps itself. The fiber bed collecting media strip can be provided to the field in different formats for use in making a mist eliminator fiber bed.

  • Patent number: 7416576
    Abstract: A fiber bed assembly for a mist eliminator that operates at high efficiency and inhibits re-entrained liquid from leaving the mist eliminator. The fiber bed assembly has a construction that facilitates rapid drainage of liquid collected by the fiber bed. A pre-filter media can be employed upstream of the primary collection media to remove larger liquid drops. The pre-filter media can be used in unique combination with other features to reduce liquid re-entrainment, and/or allow increased flow capacity.

  • Patent number: 4478809
    Abstract: This invention provides a method of removing heat from the process gas in a sulfuric acid plant having interpass and final absorption towers by indirect heat exchange with a liquid without condensing acidic vapors from said process gas. The method comprises installing first and second economizers, the second economizer having first and second sections for liquid flow. The process gas flow through the first economizer before passing through the interpass absorption tower and through the second economizer before passing through the final absorption tower. A liquid flows through the first and second economizers for indirect heat exchange with the process gas, the liquid passing sequentially through the second section of the second economizer, the first economizer, and the first section of the second economizer.

  • Patent number: 4470449
    Abstract: A shell and tube type of economizer is divided into first, second and third sections. Gas flow through the economizer flows sequentially through the first, second and third sections. The liquid first flows through the second section and then through the third and first sections. The second section serves as a preheater to increase the heat recovered from the gas stream.

  • Patent number: 4086070
    Abstract: A fiber bed separator and method are provided for separating aerosols of 3 microns and less from gases. Two fiber beds in intimate contact with one another are used. The first fiber bed, in the direction of gas flow is of fibers of at least about 5 microns mean diameter packed to a bed voidage of from about 85 to 98%, the fiber diameter and bed voidage being selected such that at design bed velocity and aerosol loading the first bed is not flooded and the residual saturation of said first fiber bed against gas drag on the liquid collected is less than the residual saturation of said bed against gravity drainage of the liquid. The second fiber bed is packed to a bed voidage of from about 85 to 99% with fibers of equal or greater mean diameter than those in the first fiber bed such that the residual saturation of said second fiber bed against gas drag is greater than the residual saturation of the bed against gravity drainage.
