Tall oil neutralisation

Tall oil production

PROCESS DESCRIPTION

In the case of tall oil neutralisation, the soaps obtained from the thin liquor are separated from the crude tall oil as a black, viscous liquid by adding an acid. Crude tall oil, depending on its origin, consists of 20 to 65 % resin acids, 15 to 55 % fatty acids and 5 to 30 % unsaponifiable parts. The recovery of crude tall oil can be carried out continuously or discontinuously, the yield is generally between 20 and 50 kg/t pulp.
