Abstract
U ovom radu simuliran je korozijski proces niskougljičnog čelika u cjevovodnom sustavu za transport nafte pri različitim procesnim parametrima. Za simulaciju je korištena programska podrška za predviđanje korozije FREECORP TM 2.0. Glavne značajke modela su: predviđanje brzine korozije uzrokovane CO 2 , H 2 S, organskim kiselinama, tj. CH 3 COOH, i/ili O 2 , simulacija rasta sloja željezova(II) karbonata i željezova(II) sulfida te kvantitativno određivanje doprinosa različitih korozijskih vrsta korozijskom procesu i identifikacija dominantne korozijske vrste. Glavni parametri ispitivanog sustava su temperatura, vrijeme, tlak, promjer cijevi i brzina strujanja vodene otopine. Parametri vodene otopine su pH-vrijednost, koncentracija korozivnih vrsta kao što su ugljikov dioksid, sumporovodik, octena kiselina, kisik i koncentracija Fe 2+ iona. Na temelju određenih ulaznih parametara, izračunata je brzina opće korozije i određen doprinos korozivnih vrsta ukupnoj brzini.
Abstract (english)
This paper aims to study the corrosion process of mild steel in a pipeline system for oil transport as different process parameters are simulated. FREECORP TM 2.0 corrosion prediction software was used for the simulation. The main features of this model include: prediction of corrosion rate caused by CO 2 , H 2 S, organic acids, i.e. CH 3 COOH, and/or O 2 , simulation of iron carbonate film and iron sulphide film growth and identification of major corrosive species by quantifying respective contributions from various species. The main parameters are temperature, time, pressure, pipe diameter and liquid velocity. The parameters of the aqueous solution are pH and concentration of corrosive species such as carbon dioxide, hydrogen sulphide, acetic acid, oxygen and concentration of Fe 2+ ions. Based on specific input parameters, the uniform corrosion rate was calculated and the contribution of corrosive species to overall corrosion rate was determined.
