Tall oil, also called "liquid rosin" or tallol, is a viscous yellow-black odorous liquid obtained as a by-product of the Kraft process of wood pulp manufacture when pulping mainly coniferous trees. The name originated as an anglicization of the Swedish "tallolja" ("pine oil"). Tall oil is the third largest chemical by-product in a Kraft mill after lignin and hemicellulose; the yield of crude tall oil from the process is in the range of 30 – 50 kg / ton pulp. It may contribute to 1.0 - 1.5% of the mill's revenue if not used internally.

Famous quotes containing the words tall and/or oil:
“And then a tall fat man with stringy hair
And a manner that was innocent of sin,
His galluses greasy, his eyes coldly gray,
Appeared, and with a gravely learned air
Spoke from the deep coherence of hell....”
—Allen Tate (1899–1979)
“Eat what you can get.
Where’s the salt
in this dump of a village?
And, Lucky Man,
what’s the use
of a salty thing
if there’s no oil in it?”
—Hla Stavhana (c. 50 A.D.)
