Using coal mine saline water to produce chlorine

Journal Article:

Abstract

Utilizing hard coal mine waters with salt concentration reaching 140 kg/mat3 in the chemical industry would significantly reduce the cost of protecting the natural environment from salt. The Institute of Chemistry and Inorganic Technology of the Silesian Technical University in Gliwice developed an efficient technology of producing chorine from underground black coal mine waters. A scheme of the technology is explained: double stage brine purification with magnesium hydroxide as by-product. During the first stage magnesium is precipitated using sodium hydroxide; after increasing salt content in the brine calcium and a low percentage of magnesium are removed by lye-sodium method. During the second stage sedimentation rate increases to 1.4 mm/s, and volume of sludge is only 1%. Magnesium hydroxide is removed using a method patented in Poland (after adding a flocculant magnesium hydroxide is left untouched). Only at a later stage does sedimentation occur. The proposed technology of utilizing mine water will be tested in an experimental plant which will be built at the Ziemowit black coal mine. (7 refs.) (In Polish)
