ABSTRACT:
This invention provides vertically disposed fiber bed elements and separators containing the same wherein "bubble re-entrainment" of a collected liquid phase in a gas stream flowing through the fiber bed is substantially eliminated or reduced. "Bubble re-entrainment" refers to that re-entrainment of liquid which occurs at the bottom of the fiber bed where the cumulative drainage of the liquid is at its maximum. This is accomplished by providing at the bottom of the fiber bed a vertically disposed gas flow baffle means such as, e.g., a baffle plate, such that some portion of the fiber bed is disposed downstream of the baffle means and shielded by the lee side of said baffle means from the moving gas stream, said shielding being effective throughout the shielded portion of the fiber bed to reduce the bed velocity of any gas flowing therethrough to below a bubble re-entraining velocity. In a preferred embodiment, the fiber bed is a bicomponent bed of two fiber beds, the first or upstream bed being of at least 5 micron mean diameter fibers, the second or downstream bed being of somewhat coarser fibers than, in intimate contact with, the first bed, and the baffle means being disposed at the interface between the two beds.
