Abstract

A paired stage flash evaporator unit (10) is provided with an elongated shell (15) having respective higher temperature and lower temperature evaporation chambers (11 and 13) extending along a bottom portion of the shell space and separated from each other by an interstage elongated partition wall (44). A condenser tube bundle (30) extends longitudinally between opposite shell end walls (18 and 20) in an upper portion of the shell space. A transverse interstage partition (32) separates the tube bundle into separate condenser chambers (34 and 36). Each condenser chamber (34 and 36) is paired with an evaporation chamber (11 and 13) by means of shroud (35 and 37) and other isolation structure thereby forming two paired stages in the unit. In each stage, a liquid separator mesh (40, 41) extends coextensively with the evaporation chamber (11) and both condenser chambers (34 and 36) to direct vapor from the evaporation chamber (11) into a flow path above the mesh (40). A distillate collection tray (38) is supported beneath the tube bundle (30) and it is divided into stage-separated tray portions (38a and 38b) by the transverse interstage partition (32). A collection duct (50) extends through a plant train of such evaporator units (10) beneath the interstage partitions (32) and tray portions (38a and 38b) in such evaporator units (10). The duct (50) is internally partitioned to receive distillate from each stage and cascade the accumulated distillate to the next stage.
