Abstract: A thermal desalination system adapted to produce distilled water from feed water which may be sea water, based on a forward feed evaporator made up of a main water feed line, a vapor feed line, a distilled water main line and any number of effect groups. The effect groups include any number of effects which in turn include vapor inlets, water inflow lines, concentrate outflow lines that drain into a common concentrate drainage line, a vapor and water outlet in fluid communication with the distilled water main line, and heat transfer means that condense part of an inlet vapor to produce the distilled water.

Abstract: A multi-effect evaporator, having an upstream and a downstream end, adapted for distillation of water. It includes a plurality of effects connected in a series manner and arranged into groups. Each group has a common parallel water feed inlet adapted to supply all effects in the group with feed water. The evaporator further includes a main feed water line in fluid communication with the most upstream group. An array of heaters is disposed along the line, adapted for heating the feed water before its entry into the effects of the latter group. Each effect includes means for forwarding the second outlet vapor into one of the heaters for heating the feed water. Each group includes a pump adapted to extract the concentrate from the effects of the group and pump it into the common parallel water feed of an adjacent downstream group.

Abstract: An evaporator having more efficient heat transfer tubes, that are either or both coated and vertically corrugated. The coating, though reducing the heat transfer co-efficient, lengthens the time between cleaning treatment to increase the overall efficiency of the evaporator. The corrugation of the tubes controls the film characteristics and enhances evaporation from the film upon condensation of vapor within the tubes. The corrugation profile is selected to enhance waviness and turbulence of the films and thereby increase evaporation and condensation and hence the effectivity of the evaporator.

Abstract: A stream of non-condensable gases that include hydrogen sulfide which are produced by a geothermal plant are disposed of by first compressing at least a part of the stream to form compressed gases. Spent geothermal liquid produced by the power plant is pressurized, and directly contacted with the compressed gases to produce an effluent containing substantially all of the hydrogen sulfide, which can be disposed of in a re-injection well, and a stream of pressurized gases substantially free of hydrogen sulfide which can be released to the atmosphere. Before the stream of pressurized gases are released to the atmosphere, such stream preferably is expanded in a turbine for producing power. Also, preferably, this power so produced is used to compress the non-condensable gases thus reducing the net power consumed. In a further alternative, where chemicals are utilized, almost all of the hydrogen sulfide is stripped from the stream of gases.
