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.
Claims16
A process for treating lignocellulosic pieces with a water-soluble lignocellulosic material preservative, the process comprising the step of:
- preparing a water-based preservative solution by dissolving the water-soluble lignocellulosic material preservative comprising disodium octaborate tetrahydrate (DOT) in a concentration above 40% wt, in water at a preparation temperature;
- lowering a temperature of the water-based preservative solution from the preparation temperature to a contact temperature lower than the preparation temperature;
- and
- submersing the lignocellulosic pieces with the water-based preservative solution at the contact temperature, the contact temperature being between 85° C. and 95° C.
