Thermal Unit Operations
this can be achieved depends on the thermal unit operation regarded. Generally the interface between the two phases is maximized by dispersing one of the phases with-in the other to form small drops, bubbles or thin films. The concentration gradient can e.g. be maximized by operating the equipment in a counter-current fashion (Ge-genstrom).
