Abstract
U radu je opisana zaštita nadzemnih spremnika za naftu inhibitorima korozije. U teorijskom dijelu rada obrađeni su nadzemni spremnici za skladištenje naftnih derivata izrađenih od nelegiranog ugljičnog čelika. Opisane su metode korozijske zaštite skladišnih spremnika. Detaljnije su obrađeni inhibitori korozije. U eksperimentalnom dijelu rada provedena su ispitivanja trajnosti zaštite plutajućeg premaza M-645 u 3,5 % otopini NaCl i prirodnoj morskoj vodi. U ispitni medij dodana su sredstva za kemijsko vezivanje kisika i biocid u cilju istraživanja njihovog utjecaja na učinkovitost zaštite od korozije. Elektrokemijskim ispitivanjem provedenim na uzorcima određeni su korozijski potencijal (Ecor), polarizacijski otpor (Rp), jakost korozijske struje (Icor), te brzina korozije (vcor). Provedena su gravimetrijska mjerenja i vizualna kontrola prije i nakon uranjanja u ispitni medij. Ispitano sredstvo na bazi inhibitora korozije pokazalo se kao učinkovito rješenje za zaštitu od korozije kod hidrostatske probe ugljičnih čelika.
Abstract (english)
In this thesis, the protection of above-ground oil storage tanks with corrosion inhibitors is described. In the theoretical part of the thesis, a overview of above-ground storage tanks of oil derivatives made of unalloyed carbon steel is given. Furthermore, methods of corrosion protection of storage tanks were described in the theoretical part as well, including detailed explanation of corrosion inhibitors. In the experimental part of the work, the durability tests of the protection of floating coating M-645 in 3.5% NaCl solution and natural sea water were carried out. Agents for oxygen scavanger and biocide were added to the test medium, in order to investigate their influence on the effectiveness of corrosion protection. Open circuit potential (Ecor), polarization resistance (Rp), corrosion current (Icor), and corrosion rate (vcor) were determined by electrochemical testing of the samples. Gravimetric measurements and visual control were performed before and after immersion in the test medium. The tested agent based on corrosion inhibitors proved to be an effective solution for corrosion protection during hydrostatic testing of carbon steels.
