Tall Oil


Tall oil is one of the most commercially important by-products of the paper making process. After the black liquor soap is converted to tall oil, or “liquid rosin”, by a boiling process with sulfuric acid, it becomes a dark brown viscous liquid containing about 95% equal amounts of rosin acids and fatty acids. This liquid requires a heavy duty industrial positive displacement pump capable of handling abrasives, varying pressures and running dry without damage.
