Abstract




This study is based on the use of citric acid (CA) as inhibitor for the formation of scale on the stainless steel using drilling water (102°F) in domestic pipes. This paper shows the evolution of the behaviour of CaCO3 using chronoamperometry, impedancemetry and the fast controlled precipitation method. The study of citric acid electrochemically demonstrates a medium inhibition of calcite with a concentration of (70 ppm), while chemically, the inhibition reached 80%. The XRD showed that the intensity of a preferential orientation (104) corresponding to crystallographic planes of calcite decreases and the intensity of this pre- ferential orientation decrease when CA is added in drilling water.
