Abstract
Utilization of coal mine saline waters is regarded as the most appropriate method of solving the ecological problems created by these waters in Poland. One of the methods of utilizing the most concentrated saline waters - called coal mine brines, which is presently being considered - consists in using them for chlorine production in a diaphragm electrolysis process. On the basis of investigations a technology for preparing mine brine for diaphragm electrolysis has been developed. The process consists of purification of brine with a high magnesium ion concentration while obtaining, as a by-product, magnesium hydroxide and bringing the brine to the state of saturation using sodium chloride from the catholute evaporation process. The technology has been verified on the diaphragm electrolysis experimental installation. It offers low energy consumption and waste-free operation.
