摘要： A method for the recovery of at least one of an organic acid or an organic acid amide, such as heat stable lactic acid or lactamide, from a feedstream (1) including mixing said feedstream that comprises the organic acid and/or organic acid amide with at least one azeotroping agent (2) in reactor (3). The azeotroping agent is a hydrocarbon capable of forming at least one heteroazeotrope with the organic acid or the organic acid amide. The mixture is heated to produce a vapor stream (11) and the vapor stream is further heated to separate components or it can be condensed in condenser (12) into a liquid stream. The liquid stream is capable of being separated into a first phase (18) and a second phase (17). The liquid stream can be further distilled or, alternatively, the two phases of the liquid stream can be separated. The first phase can be separated from the remainder of the liquid stream resulting in recovery of the organic acid and/or organic acid amide. The recovered organic acid and/or organic acid amide can be further purified and/or concentrated from the separated first phase.

摘要： Disclosed herein is a compact vacuum distillation device for the distillation of liquids. The device comprises an evaporator (14) in which liquid is evaporated and a condenser (24) where the liquid is condensed, both evaporator (14) and condenser (24) units are contained within the same distiller vessel (42). A refrigeration cycle (14, 28, 24, 10) is used to supply heat to boil the liquid being distilled and to condense the vapor. The distiller vessel (42) also includes a novel heater vacuum generator (30, 32, 34) which creates a vacuum inside the vessel. This vacuum allows boiling of the liquids at a reduced temperature thus allowing the use of a refrigeration system as the heating and cooling source that reduces energy consumption. The device will produce distilled liquid at a cost less than 25 - 50 % of simple distillation. Due to the compact size and the use of the same components as a conventional refrigerator, this device can be integrated into the refrigerator system and produce distilled water.
