Abstract
Cilj ovoga rada bio je utvrditi učinkovitost provođenja unutarnje katodne zaštite čeličnih separatora slojne vode s vanjskim izvorom struje u odnosu na češće primjenjivane inhibitore korozije. Stjenke čeličnih separatora slojne vode oponašale su dvije pločice od ugljičnog željeza uronjene u realni uzorak slojne vode. Jedna od njih bila je katodno zaštićena, a druga nije. Eksperiment se provodio 40 dana bez prekida pri temperaturi od oko 55 °C i uz miješanje otopine. Brzina korozije određena je na temelju metode gubitka mase. Dobiveni rezultati pokazuju da katodna zaštita doista smanjuje brzinu korozije ugljičnog čelika u slojnoj vodi i to već pri blagoj katodnoj polarizaciji.
Abstract (english)
The main goal of this work was to determine the viability of using cathodic protection, as a replacement for a more common use of corrosion inhibitors, in order to inhibit the corrosion of the inner walls of carbon steel-based formation water separator tanks. In this work, the steel walls were represented by two carbon steel plates, where one of them was under impressed current cathodic protection. Both plates were immersed in a sample of oilfield formation water for forty days. The system was heated to 55 °C and was constantly stirred using a magnetic stirrer, thus simulating real-life industrial conditions. The rate of corrosion was determined by measuring the weight loss. Results indicate that the impressed current cathodic protection does indeed lower the corrosion rate od carbon steel in formation water, even at a lower cathodic polarisation.
