Abstract
The invention relates to a process for treating vapours released from lignocellulose biomass during acid treatment at elevated temperature of the lignocellulose biomass. The process comprises condensing (3) the vapours to produce a condensate, adjusting (4) the pH of the condensate to about 9, and decanting (5) the condensate to produce turpentine, and may further comprise distilling (6) the mixture remaining after decanting to produce furfuraland a reject comprising tall oil fatty acids. The invention also relates to a corresponding system for treating vapours released from lignocellulose biomass during acid treatment at elevated temperature of the lignocellulose biomass.
