Abstract
Free chlorine is removed from materials containing it by subjecting the materials, preferably in the presence of water, to the action of carbon which has been activated with water vapour at a temperature of 800-1000 DEG C. The chlorine is converted into hydrochloric acid. The carbon should preferably be moulded to a suitable grain size before activation or may be reduced from irregularly-shaped charcoal into uniformly rounded pieces by mutual attrition in a grinding drum or the like. Water containing free chlorine may be rendered chlorine free by passage through a filter comprising a layer of the said carbon. Chlorine dissolved in organic liquids or gaseous chlorine contained in a mixture of gases can be removed by sending such liquids or mixtures of gases through filters comprising the carbon together with liquid water. These gases may also be passed up a series of scrubbers filled with the carbon down which water percolates. Solid substances may be similarly purified when in suspension in water.ALSO:Free chlorine is removed from liquids containing it by subjecting the liquids, preferably in the presence of water, to the action of carbon which has been activated with water vapour at a temperature of 800-1000 DEG C. The carbon should preferably be moulded to a suitable grain size before activation or may be reduced from irregularly shaped charcoal into uniformly rounded pieces by mutual attrition in a grinding drum or the like.
