Cellular foams have many possible uses[l-51. They also occur on distillation and absorption trays[6-8]. Consequently, over the past few decades, they have attracted considerable engineering attention. When foam on a sieve tray gets converted into froth, some recirculation occurs which has been reported in the literature [9-11]. This paper presents substantially more experimental observations on recirculating semi-batch foam columns. These observations pertain to the following three hitherto unreported aspects of foam columns: (i) number of recirculation cells; (ii) critical liquid holdup at the foam-gas interface; and (iii) effect of clear liquid height on the liquid holdup profiles.
