PROCESS FOR THE CONTINUOUS ANALYSIS OF CHLORIDE IONS PRESENT IN THE HEAD-WATERS OF A DISTILLATION COLUMN FOR HYDROCARBONS, AND ANALYSING APPARATUS FOR CARRYING OUT THIS PROCESS

摘要

This process of analysis comprises the following operations taken in this order or in a different order:… - abstracting from the said head-waters an offtake flow of water to be analysed,… - removing the hydrocarbons and the suspended matter from the said offtake,… - injecting nitrogen into this offtake to entrain hydrogen sulphide and residual hydrocarbons, oxidising the sulphide ions S<2><-> or HS<-> to sulphate ions,… - acidifying the said offtake,… - finally measuring, by ionometry, especially by means of a combined electrode (46), the content of chloride ions present. ……
