| titleOfInvention | RESIDUAL IRON CHLORIDE SOLUTION PROCESSING METHOD |
| abstract | method of processing residual iron chloride solution method of processing residual iron chloride solution with ferrous chloride, ferric chloride or possible mixtures thereof, and free hydrochloric acid, the method comprising: a concentration step, in which the solution of residual iron chloride is concentrated to a concentrated liquid with an iron chloride concentration of at least 30% by weight; optionally an oxidation step, in which ferrous chloride contained in the concentrated liquid obtained from said concentration step is oxidized to ferric chloride to obtain a liquid with ferric chloride; a hydrolysis step, in which the liquid containing ferric chloride optionally obtained from the oxidation step is hydrolyzed at a temperature of 155 - 350 ° C while maintaining the ferric chloride concentration at a level of at least 65% by weight, to generate steam containing hydrogen chloride and liquid containing ferric oxide, a separation step, in which ferric oxide is separated from said liquid containing ferric oxide obtained in said hydrolysis step and a recovery step, in which steam containing hydrogen chloride obtained in said the hydrolysis step is condensed to recover hydrochloric acid at a concentration of at least 10% by weight, preferably at least 15% by weight, the condensation energy of the vapor containing hydrogen chloride obtained in the recovery step being directly or indirectly used as a heating source for said concentration step, the concentration step being carried out under reduced pressure. |
