    Abstract: The present invention relates to a method for continuous acetylation of wood elements. The acetylation is conducted with an acetylation medium at a pressure of at least 1.5 barg in a substantially oxygen free environment. Alternatively, the method according to the invention comprises the steps of: (a) feeding wood elements in a substantially oxygen free environment to a continuous acetylation reactor, and (b) treating the wood elements with an acetylation medium in the continuous acetylation reactor under wood acetylation reaction conditions, at a pressure of at least 1.5 barg. The process according to the present invention allows to acetylate wood elements to a high acetyl content in a very efficient way, without compromising on the quality of the material. The acetylated wood elements can be used in the production of medium density fibreboards with superior qualities such as dimensional stability and durability.

    Abstract: Title: A system and a method for transferring solid particles from a first environment at a first gas pressure to a second environment at a second gas pressure Abstract A system for transferring solid particles from a first environment at a first gas pressure to a second environment at a second gas pressure. The system comprises a first rotary valve having an inlet which is in fluid communication with the first environment, a second rotary valve having an outlet which is in fluid communication with the second environment, and an intermediate housing bounding an intermediate channel, of which an inlet is fluidly connected to an outlet of the first rotary valve and of which an outlet is fluidly connected to an inlet of the second rotary valve. The intermediate channel is fluidly connected to a third environment maintained at a third gas pressure. The third gas pressure is higher than both the first gas pressure and the second gas pressure or lower than both the first gas pressure and the second gas pressure.

    Abstract: Disclosed is the integration of the production of acetic anhydride from ketene, and the acetylation of wood using acetylation fluid comprising acetic acid and acetic anhydride. The invention involves recirculating acetylation fluid recovered from wood acetylation to a unit for the production of acetic anhydride from acetic acid and ketene. The acetic anhydride product stream can, in turn, be directly used as a wood acetylation fluid.
