Abstract
A method and apparatus for continuously removing agglomerable particles from a liquid, such as for example tall oil soap particles from the black liquor formed in a wood pulping process, are disclosed wherein a substantially continuous stream of the liquor is supplied to a first container wherein the liquor is whipped in the presence of air to agglomerate soap particles into particles of substantially larger size. The foam is then removed from the first container, near the top of the container, and supplied in a deaerating apparatus which deaerates the foam and produces a mixture of liquid and agglomerated soap particles. This mixture is then supplied to a skimming tank wherein the soap particles float to the top of the tank and are removed while liquid is drained from the bottom of the container.
