  • Method of and apparatus for high intensity heat and/or mass transfer between two or more phases
    Patent number: 4009751
    Abstract: Heat and/or mass transmission between two or more phases is accomplished by a helical guide for both phases inside a column flowing either in counter-current or in co-current. The phase with a higher specific mass flows within the column along a continuous track formed by an outer helix; the phase with a lower specific mass flows along an internal helix within the column. These flows are brought about by suitable elements which are built-in in a cylindrical column.
