Abstract
An Isopropyl Alcohol (IPA) tank vapor/liquid phase separator for collecting liquid while still allowing for efficient vapor flow in an IPA tank includes a first row and a second row of spaced-apart coplanar parallel catch trays. Vapor flows upwardly through the openings between the catch trays. The catch trays are arranged so that contaminated IPA condensate falls into either the first or second row of catch trays. In one embodiment, both of the catch trays are upright V-shaped or upright semi-circular-shaped. In another embodiment the catch trays are formed as plates with staggered holes formed therein for upward passage of vapor and for downward collection of condensate.
