ABSTRACT:
A chloride analyzer includes an inlet valve and filters for process water to be analyzed, as well as a pH electrode to verify the pH value of the incoming liquid before further treatment. A stripper bubbles stripping air through the process water to remove hydrocarbons and hydrogen sulfide therefrom, and the discharge line from said stripper feeds a reaction vessel to which also reagent from a supply vessel is passed. After a suitable reaction time, optionally followed by a further air stripping operation through air supply line, the reaction products are fed via line to an ionometry measuring cell where chloride analysis is carried out using a specific ion selective electrode.
