摘要： Method and apparatus for separating volatile contaminants from a liquid to be continuously distilled. A continuous still comprises evaporator (1) having a heating coil (2), and condensor coil (6), and distillate collector (5). An entrainment device (11) removes distillate (13) from collector (5) via line (10) and reduces pressure in evaporator (1). Feed liquid (21) containing volatile contaminants is charged batchwise to a pre-chamber (20) at sub-atmospheric pressure which is then sealed (valve 22) from feed supply (21). Volatile contaminants are extracted from the charge in prechamber (20) via line (26) and entrainment device (32). Pre-chamber (20) is subsequently placed in communication (via valve 25) with evaporator (1) whereby to equilibrate pressure between evaporator (1) and pre-chamber (20). Liquid levels in pre-cheamber (20) and evaporator (1) then equilibrate whereby decontaminated liquid is automatically transferred (line 36) from the pre-chamber (20) to evaporator (1) to make up for distillate removed from evaporator (1). Valve (25) is then closed and the cycle repeated. The valves are automatically operated in a timed sequence.

摘要： Apparel us for impregnating a porous substrate (e.g., wood) with an active agent, including a reservoir for containing a low boiling fluid, a controllable first fluid pathway to permit fluid to flow from the reservoir to a treatment vessel, a fluid junction for introducing the active agent into the first fluid pathway to permit mixing of the active agent with the low boiling fluid to produce an impregnation fluid containing an initial level of active agent and a controllable second fluid pathway to allow fluid to flow from the treatment vessel to the reservoir. The treatment vessel contains the porous substrate while it contacts the impregnation fluid in a liquid state to produce a treated substrate impregnated with the active agent. Also, a method for impregnating a substrate with an active agent, including preparing an impregnation fluid including a low boiling solvent and an active agent, and optionally a co-solvent, contacting the porous substrate with the impregnation fluid in a liquid substrate in an impregnation chamber and removing the impregnation fluid.

摘要： A low pressure distillation apparatus in which evaporation takes place at sub-atmospheric pressures. An evaporation chamber has a feed liquid inlet port, a concentrated liquid outlet port, and a vapor outlet port. The vapor outlet port is in communication with a vapor treating device immersed in distillate in a distillate chamber. The preferred vapor treating device is a rotating impeller pump which reduces the pressure in the evaporation chamber to a working pressure, draws off vapor boiled from the liquid in the evaporation chamber, entrains the vapor in a stream of distillate, and condenses the vapor in the stream of distillate to transfer the latent heat of condensation of the vapor directly to the distillate.
