TL;DR: In this article, the vapours are substantially liquefied by heat exchange with a coolant which evaporates during this, the coolant vapour is heated by compression to a temperature above the evaporation temperature and is then condensed with the liquid to be evaporated.
Abstract: In the process, the vapours are substantially liquefied by heat exchange with a coolant which evaporates during this, the coolant vapour is heated by compression to a temperature above the evaporation temperature and is then condensed by heat exchange with the liquid to be evaporated and the liquefied coolant is then depressurised and returned to the heat exchange with the vapours

TL;DR: In this article, an apparatus and a method for the removal from biodiesel of excess water resulting from hygroscopic absorption during transport or storage is presented, which can be connected directly to a warehouse for decontamination of the extracted water by means of decanting or recycling.
Abstract: The present invention refers to an apparatus and a method for the removal from biodiesel of excess water resulting from hygroscopic absorption during transport or storage. The apparatus is compact, can be transported on a mobile base and can be connected directly to a warehouse for decontamination of the extracted water by means of decanting or recycling. The apparatus for drying biodiesel comprises: - a device (2) for extraction of the biodiesel from a warehouse (1); - an evaporation circuit comprising a return pipe (3), heat exchangers (3c and 3e) and a flash reactor (4); - a condenser (5) to condense waste vapours; - a collector for the waste vapours (6) condensed in the condenser (5); and - a centrifugal pump (5c) for elimination of the waste vapours.

TL;DR: In this paper, the vapours from one steam distillation zone are partially condensed and the uncondensed steam and entrained material returned to the previous zone while undistilled residue is forwarded to the following zone.
Abstract: In the distillation of decomposable organic materials in a series of zones in cascade, with the aid of steam in at least two consecutive zones, the vapours from one steam distillation zone are partially condensed and the uncondensed steam and entrained material returned to the previous zone while undistilled residue is forwarded to the following zone. Decomposable materials specified are fatty acids and their esters, alcohols, nitriles and amines and tall oil acids. A fatty acid mixture comprising mainly palmitic and oleic acids is fed via line 10 into a tower 1 maintained under reduced pressure and from which odiferous vapours are removed via condenser 14 whilst the bottoms are fed via line 11 into a tower 2 separated from a tower 3 by an imperforate plate 13. Vapours from tower 2 comprising mainly palmitic acid are condensed in a condenser 24 which communicates with a steam ejector pump 27, the steam from which, together with entrained vapours from the condenser 24, passes over heating coils 30 into the tower 1. The bottoms from tower 2 are fed into tower 3, the tarry bottoms from the latter being removed. Vapours from tower 3, comprising mainly oleic acid, are condensed in a condenser 40 which communicates with two steam ejectors 44 and 46, the steam from which, together with entrained vapours from the condenser 40, passes over the steam coil 48 into the column 2.
