A pump for a radioactive waste concentrator in a shielded enclosure is mounted on a wheeled vehicle that travels on tracks, and a spare pump is mounted on an identical wheeled vehicle outside of the shielded enclosure, adjacent the tracks. If the pump fails, it is wheeled out of the shielded enclosure, and the vehicle carrying the spare pump is put on the tracks and wheeled into the enclosure for quick connection to the concentrator.

Radioactive waste concentration

A continuous process for the recovery of chemicals in saline water including the steps of converting the sulfates in the saline water feed to sodium sulfate; separating and recovering in the oxide forms essentially all of the magnesium and calcium from the saline water feed; then preparing a sodium chloride fortified solution by mixing the feed with recycled sodium chloride; crystallizing and re-crystallizing and then separating sodium chloride crystals, preferably in two evaporative crystallization processes; stripping bromine from the sodium chloride depleted solution; crystallizing and then separating sodium chloride and sodium sulfate crystals from each other and then from solution; recycling the separated sodium chloride to the first sodium chloride crystallization step; separating residual sulfates from the solution; crystallizing and then separating sodium chloride crystals; recycling the separated sodium chloride to the first sodium chloride crystallization step; crystallizing and then separating potassium chloride from the solution; and recycling the resulting solution to the last sodium chloride crystallization step. Substantial quantities of potable water are produced by the process. In a preferred embodiment, sodium chloride is electrolytically converted to sodium hydroxide, chlorine and hydrogen. Part of the sodium hydroxide is used in the process, the remainder is concentrated and flaked. Part of the chlorine is liquified, the remainder is combined with a portion of the hydrogen to form hydrochloric acid. Finally, the steam boiler flue gas may be combined with sodium hydroxide to produce the sodium carbonate used in the process.

Process for recovery of chemicals from saline water

A heat exchanger employs a variable number of repositionable baffles in its headers to permit changing the number of passes made by the fluid processed therein.

A liquid-gas separator may be used with a liquid concentrator for returning entrained liquid. The separator employs serially arranged mesh pads of different cross-sectional areas. The largest pad is closest to the liquid-gas inlet, and the smallest pad is closest to the gas outlet.

Entrainment separator apparatus

In the condensing operation of a waste concentration system, water vapor is condensed, by cooling, into liquid condensate which is reboiled so as to drive off and strip gas that has been redissolved into such condensate. The stripped and driven off gas is directly recombined with the undissolved gas without being mixed with the main body of vapors. The resulting mixture is further cooled to remove the remaining portion of water vapor after which the noncondensible gas stream is filtered and cooled.

Pure distillate recovery system

A vertical cylindrical liquid-gas separator of an evaporator is connected to horizontal cylindrical piping by a rectangular gas discharge conduit that promotes optimum gas flow characteristics through the separator.
