Abstract

L'invention concerne un procédé d'obtention en continu d'acide chlorhydrique présentant une teneur constante en HCl, comprise entre 20 et 36 %, par élimination du gaz chlorhydrique de gaz de combustion, les gaz chauds de combustion étant refroidis brutalement par un acide chlorhydrique obtenu au préalable. L'installation comporte un circuit de refroidissement 1-5, de lavage 13-17, de lavage 21-25, dont les cuves de stockage sont reliées pour permettre le maintien de la concentration constante. Pollution atmosphérique très réduite.
