Continuous Extraction of Crude Tall Oil |
|
| Abstract: | Abstract A new continuous extraction method for fatty and resinic acids separation from crude tall-oil sodium salts aqueous solutions by countercurrent contact with n-heptane was developed using a bench-scale multistage mixer-settler plant. The data obtained showed good recoveries and high purities, especially for resinic fraction stream, for which the consumption of chemical reagents is virtually obviated with consequent economic advantages. |
