Cathodic Protection System for Hot Sulphur Tank BottomA Cathodic protection system was designed and installed for the external bottom steel surfaces of a hot sulphur storage tank. The impressed current type system comprises a transformer rectifier to provide d.c. current to a grid of conductor bars and mixed metal oxide ribbon anodes installed in the tank foundation between a plastic containment layer and the tank bottom. During service the tank bottom temperature is over 100 degree C and the challenge was to define the right design location and distance of anodes and reference electrode and to specify the right materials to avoid detrimental effects of temperature.This paper presents the design data and the survey results registered during the commissioning of the CP system carried out before and after the filling of the tank.
