The principles of drying solid materials by exposure to organic vapour are considered. The composition of the vapour-drying atmosphere is discussed in relation to the equilibrium moisture content of wood. Phase diagrams are presented showing the variation of composition and equilibrium moisture content with pressure and temperature when perchloroethylene is used as the drying agent. The interaction of the drying atmosphere with the wood, and its effect on the temperature of the wood interior, are examined. Evidence is presented that during vapour drying, the mechanism controlling the rate of vapour phase movement of moisture through the wood may be Poiseuille flow
