ABSTRACT:
Apparatus for use in fractionation, stripping, absorption, and the like, wherein a column or tower has plural vertically spaced trays each consisting of two vertically spaced rows of strips which are parallel and of which the strips of the lower row are centered below the spaces of the upper row, and has a separator above each said tray consisting of plural vertically spaced rows of upwardly facing channels which are parallel and of which the channels of one row are centered between the channels of the adjacent row or rows, the trays and separators occupying a major portion of the cross sectional area of the tower and the remainder of the cross sectional area of the tower being occupied by downcomers, whereby the tower has a major portion of its cross sectional area used for upflow of vapor and liquid, or vapor. The towers or columns according to the invention result in reduced size and cost as compared with conventional apparatuses, and result in improved efficiencies and performance.
