Abstract
The gases are passed through a cell containing a first solution for dissolving the hydrochloric acid, subjected to coulometric measurement of the chloride ion content Q, passed through a vessel for absorbing the hydrochloric acid and chlorine, the organochlorine compounds contained in the remaining gases being then burnt in a combustion chamber. The combustion gases are passed through a second solution for dissolving the hydrochloric acid liberated by the organochlorine compounds, subjected to a second coulometric measurement of the chloride ion content q, the ratio q/Q being determined by a computer.
