Abstract: An improved salt basket for dewatering solids, particularly salts resulting from evaporation of industrial wastewaters. The salt basket system includes a pressurizable vessel having a screen floor situated above a bottom liquid collection head, an inlet for the brine/solids slurry from which solids are to be separated and dried, an inlet for air, an inlet for steam (the latter two inlets may be combined, where convenient), an inlet for solids free feed, and a drain outlet (these two may be combined where convenient into a combination feed/drain connection). Preferably, an automated system for introducing feed brine and for removing the solids product is provided. For safety, a pivotally attached lower door has a hydraulic failsafe closure mechanism and locking safety latches to prevent the door from inadvertently opening.

Abstract: Concentrated alcohol and distillery slop are produced from fermented beer with a reduced amount of energy by use of a multiple effect distillery slop evaporator in which evaporator vapors from one or more effects are used to strip alcohol from the fermented liquor before they are returned as heat source for the next succeeding effect, and by using vents from the partial condensation of these vapors in an evaporator effect as the principal heat and alcohol source for the rectification system. Condensed vapors from the vented evaporators and the bottom stream from the rectifier are stripped of their remaining alcohol content in a condensate stripper. The overhead stream from the condensate stripper can also be used as a heat source for an evaporator effect before being fed to the rectification system as a source of heat and alcohol.

Abstract: Concentrated alcohol and distillery slop are produced from fermented beer with a reduced amount of energy by employing a vapor recompression distillery slop evaporator in which evaporator vapors are used to strip alcohol from the fermented liquor before they are returned as the heat source for evaporation. Vents in the evaporator permit passage of uncondensed vapors used to drive the evaporator to a rectifier, in which they constitute the principal heat and alcohol source. Condensed vapors from the evaporator and the bottom stream from the rectifier are stripped of their remaining alcohol content in a condensate stripper, which is also driven by the recompressed vapors from the evaporator. This prevents dilution of the slops and the additional energy cost that would be necessary if the water content of these streams had to be removed in the slop evaporator.

Abstract: A forced circulation evaporator and method of use is disclosed that make use of a rotating impeller to both circulate liquid past the heating surface of the evaporator and to effect separation of liquid from vapor. A plurality of passage tubes acts as a generator of a liquid-vapor mixture. The impeller provides centrifugal force vectors to propel the liquid entity against the side wall of the separation zone to thereby leave the vapor to egress from the separation zone at a point near the axis of said impeller. Thus, the centrifugal force acts upon the varying densities of liquid versus vapor to cause separation more rapidly than under the mere influence of gravity.

Abstract: An apparatus and method for the adiabatic flashing of liquids and more particular, to flashing in a series of sequential stages to obtain vapor at successively lower pressure for each succeeding stage. A common application of such flashers is in the multistage flash process for desalination of sea water and brackish water.

Abstract: A multiple effect evaporator in which the feed is progressively preheated in an indirect falling film preheater by vapors from the lower temperature effects and then further preheated by direct contact with vapors from higher temperature effects, said preheated feed being degassed during said direct contact preheating, prior to evaporation.
