Abstract
Abstract Apparatus for transferring heat and/or mass in fluid to fluid contact apparatus wherein at least one fluid is liquid, comprising a housing in which a plurality of transfer sections are tandemly arranged. Each transfer section comprising a plurality of vertically disposed planar structures spaced from each other by spacers having projections forming gaps for flow of one fluid. The housing being spaced to provide for movement of the other fluid from between the planar structure of one to those of another.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
163 words
Apparatus for the mass or heat transfer between fluid phases comprising a. a vertical housing adapted to receive a primary fluid at its upper end for downward flow and a secondary fluid at its lower end for flow upwardly counter to said primary fluid, b. a plurality of transfer sections arranged adjacent each other in tandem within said housing, each of said transfer sections comprising 1. a plurality of vertically disposed substantially planar structures 2. spacer means located between said structures along one edge thereof for separating said planar structures from each other providing distributing passages for flow of primary fluid thereover, c. said housing having an enlarged portion surrounding the juncture of adjacent transfer sections with said spacer means and forming a chamber for movement of said counter flow fluid about said spacer means from the structures of one section to the structures of the adjacent section, said spacer means defining with said structures vertical openings along the faces of said structures.
