摘要： A distillation tower (1) has a plurality of liquid sidestream lines (5, 6, 7) and a multi-stage sidestream stripper (13) which includes a respective stripping section (14, 15, 16) for each sidestream line housed in a common, upright, cylindrical shell (28) which allows vapor to pass freely from each stage to the one above. Partial vaporization of each sidestream is achieved by applying a vacuum to the top of the stripper shell (point 21) and/or introducing strip gas at the bottom (point 20). Because the vapor passes serially through the stripping sections from the bottom of the stripper (13) to the top, the need to supply strip gas separately to the stripping sections and/or apply vacuum individually is avoided. The separation between the sidestream products is improved by including, in each stage, a rectification zone (22, 23, 24) positioned above the stripping section.

摘要： A solvent recovery system is provided which is characterized by improved efficiency and safety. The system includes an evaporator unit having a heat source for vaporizing contaminated solvent. The resulting vapors are subsequently liquified in a condensing unit. During evaporation and condensation of the solvent, a negative pressure is maintained within the system using a vacuum generator. After condensation, the liquid solvent passes into at least one accumulator which is periodically drained. The accumulator and vacuum generator operate in synchronization so that a vacuum is maintained in the system while drainage of the accumulator occurs. Since the evaporation and condensation systems of the invention are maintained at a negative pressure, any leaks therein do not result in the escape of flammable vapors.

摘要： A de-salinator 10 for brackish- or salt-water has a heat insulating shell 11 closed by end plates 12. A heat exchanger 22 in the bottom of the chamber 13 is heated by engine coolant from a marine engine 27, while a pair of condensor coils 19, connected to manifolds 33, 34, use sea water to cool the fresh water vapour which is drawn off by outlets 21. The engine driven pump 37 which draws the water through the condensor coils 19 operates an eductor 36 which generates a partial vacuum in the chamber 13, drawing off brine from the bottom of the chamber and any excess water in the chamber. The level of water in the chamber 13 is maintained by drawing off a portion of the heated water passing through the condensor tubes 19. The condensate is drawn from the outlets 21 via an eductor 46 which is driven by a suction pump 45 connected to the fresh water tank 47.

摘要： A process for the nondegenerative distillation of C.sub.6 -C.sub.24 -fatty acids, of the type obtained by splitting natural fats and oils or by synthetic processes, such as for example the oxidation of paraffins, the crude product is thermally dried under reduced pressure, the dried and heated crude product is subjected to fractional evaporation in falling-film evaporators, optionally in the presence of superheated steam, and the various vapor fractions are deposited in condensers. The thermal drying process is conducted at a temperature of 60.degree.-80.degree. C. and a pressure of 90-100 mbars. The de-watered crude product is fractionated in a film-forming evaporator and, after distillation, passes to a rectification column which condenses the low boiling constituents as the main runnings.

摘要： A heat-transfer medium is heated by a solar heat collector and then adiabatically compressed. The heat-transfer medium thus compressed exchanges heat with the seawater to heat it, and is then adiabatically expanded with the heated seawater being evaporated and the steam thus produced, upon heat exchange with the seawater, changed into fresh water.

摘要： A mechanical energy conversion method and system for the restoration of dissipated heat energy, contained in natural or artificial water bodies at or near ambient temperatures, to industrial process heat, mainly in the form of steam up to 200.degree.-400.degree. C. The sensible heat contained in a water body is concentrated as latent heat in low pressure water vapor which is thermo-compressed by steam ejection to an intermediate pressure level, wherefrom mechanical compression takes over, generating highly superheated output steam. The ejecting steam is not generated in a boiler, but is continuously regenerated by the compressor and routed back for repeated ejection. The compressor is driven by a heat engine whose reject heat is collected and upgraded as well. The output of heat energy is essentially equal to the sum of the heating value of the fuel consumed and the intake of latent heat and amounts thus to substantially more than the heating value of the fuel alone.

摘要： Water containing dissolved compounds is preheated, and is then pressurized in stages of water pressure, while receiving a quantum of steam. Scale-forming compounds in the water are thermally precipitated, and clarified post-thermal water is formed. This is flash vaporized in stages corresponding to the stages of water pressure, and the flashed vapors are compressed to form each said quantum of steam. Alternately, the flashed vapors themselves comprise each said quantum of steam, by being induced into the water as it flows through an eductor means. Flash-cooled, post-thermal water, substantially devoid of scale-forming compounds, is employed as such, or more generally is evaporated to form fresh water and an end concentrate of dissolved compounds.
