MANUFACTURINGS OF TALL OIL ACID:
In the kraft process, high alkalinity and temperature convert the esters and carboxylic acids in rosin into soluble sodium soaps of lignin, rosin, and fatty acids.
The spent cooking liquor is called weak black liquor and is about 15% dry content.
The black liquor is concentrated in a multiple effect evaporator and after the first stage the black liquor is about 20–30%.
At this stage Tall oil acid is called intermediate liquor.
Normally the soaps start to float in the storage tank for the weak or intermediate liquors and are skimmed off and collected.
A good soap skimming operation reduces the soap content of the black liquor down to 0.2–0.4% w/w of the dry residue.
Tall oil acid is called raw rosin soap or rosinate.
Tall oil acid is then allowed to settle or is centrifuged to release as much as possible of the entrained black liquor.
The soap goes then to the acidulator where it is heated and acidified with sulfuric acid to produce crude Tall oil acid (CTO).
The soap skimming and acidulator operation can be improved by addition of flocculants.
A flocculant will shorten the separation time and give a cleaner soap with lower viscosity.
This makes the acidulator run smoother as well.
COMPOSITIONS OF TALL OIL ACID:
The composition of crude Tall oil acid varies a great deal, depending on the type of wood used.
A common quality measure for Tall oil acid is acid number.
With pure pines Tall oil acid is possible to have acid numbers in the range 160–165, while mills using a mix of softwoods and hardwoods might give acid numbers in the range of 125–135.
Normally crude Tall oil acid contains rosins, which contains resin acids (mainly abietic acid and its isomers), fatty acids (mainly palmitic acid, oleic acid and linoleic acid) and fatty alcohols, unsaponifiable sterols (5–10%), some sterols, and other alkyl hydrocarbon derivates.
By fractional distillation Tall oil acid is obtained, with rosin content reduced to 10–35%.
By further reduction of the rosin content to 1–10%, Tall oil acid can be obtained, which is cheap, consists mostly of oleic acid, and is a source of volatile fatty acids.
