Abstract:
A process for treating lignocellulosic pieces with a water-soluble lignocellulosic material preservative. The process comprises the step of contacting the lignocellulosic pieces with a water-based preservative solution having a contact temperature between about 70° C. and about 95° C., the water-based preservative solution containing the water-soluble lignocellulosic material preservative in a concentration above about 25% wt. A lignocellulosic treatment apparatus for treating lignocellulosic pieces is also provided.
