The apparatus passes a mixture of steam and gasses from the evaporator to the tubes of the condenser. Normandy's distiller was very complex in structure, consisting of many numerous working parts. With an elaborate layout and expensive cost, the distiller wasn't economically viable for smaller vessels.
This steam evaporator aboard HMS Belfast distilled up to six tons of fresh water per hour for the boiler and for drinking. An evaporator, distiller or distilling apparatus is a piece of ship's equipment used to produce fresh drinking water from sea water by distillation. As fresh water is bulky, may spoil in storage, and is an essential supply ...
Steam distillation is a separation process that consists of distilling water together with other volatile and non-volatile components. The steam from the boiling water carries the vapor of the volatiles to a condenser; both are cooled and return to the liquid or solid state, while the non-volatile residues remain behind in the boiling container.
Slingshot is a water purification device created by inventor Dean Kamen. [1] Powered by a Stirling engine running on a combustible fuel source, it claims to be able to produce drinking water from almost any source [2] by means of vapor compression distillation, [3] requires no filters, and can operate using cow dung as fuel.
Alembics from a 1606 alchemy book. Dioscorides's ambix, described in his De materia medica (c. 50 C.E.), is a helmet-shaped lid for gathering condensed mercury. For Athenaeus (c. 225 C.E.) it is a bottle or flask.
A vapor-compression evaporator, like most evaporators, can make reasonably clean water from any water source. In a salt crystallizer, for example, a typical analysis of the resulting condensate shows a typical content of residual salt not higher than 50 ppm or, in terms of electrical conductance , not higher than 10 μS/cm .
A copper retort A glass retort. In a chemistry laboratory, a retort is a device used for distillation or dry distillation of substances. It consists of a spherical vessel with a long downward-pointing neck.
Multiple-effect distillation or multi-effect distillation (MED) is a distillation process often used for sea water desalination. It consists of multiple stages or "effects". In each stage the feed water is heated by steam in tubes, usually by spraying saline water onto them.
