" DEAERATOR CIRCUIT FOR BITUMEN FROTH" ABSTRACT Bitumen froth streams from the primary separation vessel and secondary flotation cells are gravity transferred into one or more columns and heated and deaerated therein by passing them countercurrent to steam. The heated deaerated froth is then pumped with centrifugal pump means to the froth treatment circuit. By deaerating and heating before pumping, the froth is converted from a form difficult to pump to one which is relatively easy to pump.
