POSSIBILITY OF USING THE CORROSION RATE CONTROL SYSTEM FOR HYDROGEN SULPHIDE ENVIRONMENTS

Annotation. Purpose. The determination of the possibility of using the Corrosion rate control system for corrosion rate measurement of carbon steels in hydrogen sulphide environments. Methodology. Corrosion rate monitoring system is based on the electrical resistance method. During the study the data, obtained with the System, was compared with the gravimetric measurement data. Findings. Corrosion rate values, obtained in two independent methods, showed the good convergence. The relative error of corrosion rate measurement by the System was about 3,5 %. Originality. It was found that conductive products of the hydrogen sulphide corrosion do not affect the corrosion rate measurement by electrical resistance method. Practical value. Corrosion rate control system allows to obtain on-line the reliable data about carbon steel corrosion rate in hydrogen sulphide environments continuously and constantly.
