The Use of Sea Water Electrolysis and the Membrane between the Electrodes for Desalination of Sea Water, Production of Separately Chlorine, Hydrogen Gas and Alkalis

Abstract

Existing seawater desalination processes such as distillation or thermal distillation, reverse osmosis, electrodialysis, extraction, and crystallization have been widely used. Along with the positive qualities, these processes have serious disadvantages that lead to the complexity of their use in practice due to economic unprofitability, the complexity of the design of equipment, and the expensive and rapidly wearing out materials used. In this regard, the development of new alternative methods of seawater desalination that can eliminate the above disadvantages is of great interest. The article presents the developed multi-purpose seawater desalination method and industrial distiller, using the seawater electrolysis process, which is created by electrodes, separated by a membrane, allowing desalination of large volumes of seawater, obtaining separately valuable products: gaseous chlorine and hydrogen, NaOH in sufficient quantities simply and economically beneficial. The developed industrial distiller is a continuous operation device, which allows building parallel and serial connections of distillers, allowing controlling the productivity and quality of produced fresh water.
