Abstract
PURPOSE: In preparing hydrogen chloride from an alkali metal chloride as a raw material, to obtain clear hydrogen chloride with low volatile impurities, by heat- treating the alkali metal chloride at high temperature previously, followed by reacting it with sulfuric acid.
CONSTITUTION: The alkali metal chloride 1, e.g., NaCl, KCl, etc. is fed to the heater A, and heat-treated by the part 2 of the combustion exhaust gas 7 of the reaction furnace B at 250W750°C for not more than 10min. The treated alkali metal chloride 4 and sulfuric acid 6 are fed to the reaction furnace B. The reaction furnace B consists of the combustion chamber B' and the reaction chamber B", and the heavy oil 5, etc. is burnt in the combustion chamber B' to give heat which is transferred to the reaction chamber B". Hydrogen chloride 8 produced by the reaction of the alkali metal chloride 4 and sulfuric acid 6 is introduced from the reaction chamber B" to the cooling and absorbing column C where hydrogen chloride 8 is brought into contact with dilute aqueous solution of hydrochloric acid to give a concentrated aqueous solution of hydrochloric acid 10, which is sent to the stripper D to give clear hydrogen chloride 13.
