ABSTRACT:
A method and apparatus for separating saponified tall oil or soap from black liquor which has been stored in an open pond. During such storage, the tall oil saponifies into soap, and the soap separates somewhat and a portion of it settles with the lignin to the bottom of the pond. A submerged propeller is operated by an internal combustion engine on a boat and directs a liquid and gas stream into the layer of liquid soap "sludge" so that the soap is whipped and dispersed. The whipping action causes the soap particles to agglomerage so as to form larger soap portions. The propeller also produces small bubbles of air which become attached to the soap portions thus aiding them in floating to the pond surface. The soap forms in a layer and is pushed along the liquid surface into a discharge tank from which it is pumped to a tank truck. The soap is then hauled to a plant where it is processed.
