Absorption of Hydrochloric Acid (HCL) Treatment System

Absorption of Hydrochloric Acid (HCL) Treatment System

Absorption of HCl in water. The absorption of hydrogen chloride in water is strongly exothermic ~2100 kJ/kg HCl, which means that the absorption liquid becomes easily warm. High concentrations of HCl in water can be achieved only at temperatures lower than 40C.In order to keep these low temperatures the removal of absorption energy is necessary.
