摘要

The conversion of conventional pulp and paper manufacturing processes into an integrated forest products biorefinery has great potential in the context of sustainable development. In this paper, we present a process concept which uses induced air flotation technology for recovery of manool, a valuable bioproduct, from the condensate of the multi-effect evaporation system in the kraft pulping process. The results showed that approximately 70% (purity of approximately 35%) recovery of manool was achieved from crude manool when the aeration time was about 7 min. The glass microbeads were effective in preventing sticking, due to their hydrophobic nature, and facilitating froth collection. Also, the use of a silicone defoamer at a dosage of approximately 40 ppm mitigated excessive foaming in the process.
