ABSTRACT:
A defoaming apparatus comprising a column having three levels, a lower level, an intermediate level, and an upper level. The foam to be broken is injected into the lower level with mud. A shaft in the intermediate level serves as an aspirator. Air or another gas is injected into the shaft and the vacuum thus produced pulls the foam upwardly. The foam is discharged from the shaft against vanes located in the upper level where upon the foam is broken into gas which is discharged and liquid which is recovered. Sediment from the foam is drawn off at the bottom of the apparatus.
