A plant for concentrating a tartaric acid solution includes a first and a second evaporation unit arranged in series, a pump for feeding a diluted tartaric acid solution into the first evaporation unit, a barometric condenser placed downstream of the second evaporation unit, and a system for feeding a first low-temperature vapor into the first evaporation unit. A process for concentrating tartaric acid includes providing a plant according to the above description, performing a first concentration, by evaporation, of the diluted tartaric acid solution, inside the first evaporation unit, and performing a second concentration, by evaporation, of the partially concentrated tartaric acid solution from the first evaporation unit, inside the second evaporation unit. The plant and process for concentrating tartaric acid have the advantages of ensuring low energy consumption, allowing concentration of solutions tending to crystallization, and allowing the continuous measurement of the tartaric acid concentration to be concentrated.

A high capacity and high efficiency co-current and cross-flow vapor-liquid contacting apparatus and process is useful in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by an arrangement of offset contacting modules in horizontal stages. The modules define a co-current contacting volume and in an exemplary configuration the modules include a liquid distributor and a demister. Half modules comprise downcomers against the shell of the vessel for transporting liquid to the subjacent stage.

A salt water desalination assembly includes a tank for containing salt water. The tank has an inverted cone therein that is positioned above the salt water thereby facilitating water vapor from the salt water to condense on the inverted cone. An input pipe extends into the tank to fill the tank with the salt water. A condensate pipe extends upwardly into the tank and the condensate pipe is aligned with the inverted cone to collect the condensed water vapor for subsequent use. A stand is vertically oriented and is positioned adjacent to the tank. A reflector is pivotally coupled to the stand and the reflector is exposed to sunlight. The reflector focuses the reflected sunlight onto the tank for heating the tank and thereby facilitate the salt water in the tank to be heated for producing the water vapor.

This disclosure concerns a system and a method for removing dissolved solids from liquids. Specific implementations concern desalinating water. The system may comprise a blower, such as a thermal fan/compressor, configured to atomize a solid-bearing liquid to produce a hot, humid gas containing dissolved solids; a gas-solid separator configured to receive hot, humid gas containing entrained dissolved solids from the blower to separate the solids from the humid gas and to transmit the humid gas with solids removed through an exit port; a heater configured to heat the hot, humid gas received from the exit port of the gas-solid separator; and a condenser configured to receive heated humid gas from the heater and to condense solids-free liquid therefrom. The thermal fan/compressor may comprise a plurality of nozzles with outlets positioned adjacent atomization apertures across which a solid-bearing liquid flows and through which gas exiting the nozzles passes.
