AB  - This paper reports on progress in developing an effective method for internal pipeline corrosion control in the presence of CO2. The inhibition effect of talloil diethylenetriamine imidazoline (TOFA/DETA imidazoline) on corrosion of mild steel API X65 in CO2-saturated 3 wt. % NaCl solution was investigated by: linear polarization resistance (LPR), potentiodynamic sweep (PDS), electrical resistance (ER) measurements, and atomic force microscopy (AFM). Novel top-of-the-line corrosion (TLC) mitigation method was verified in an innovative glass cell set-up and in a large scale flow loop. It was demonstrated that TOFA/DETA imidazoline can successfully protect the mild steel surface from corrosion in CO2-saturated 3 wt. % NaCl with the inhibition efficiency up to 92%. The TLC rate of mild steel, as measured in the vapor phase using the ER probe, was reduced effectively by periodic treatment by the foam containing TOFA/DETA imidazoline corrosion inhibitor in both glass cell and the large scale flow loop. The corrosion inhibition efficiency was calculated to be higher than 90 % and the inhibition effect lasted up to 50 h.

Efikasnost organskog inhibitora, imidazolinskog derivata smeše viših masnih kiselina i dietilentriamina, TOFA/DETA imidazolina za zaštitu niskougljeničnog čelika API X65 od korozije u 3 mas. % NaCl rastvoru zasićenom sa CO2 ispitivan je primenom metode linearne polarizacione otpornosti, metode polarizacione krive, metode određivanja gubitka mase na osnovu električne otpornosti, metode mikroskopije atomskih sila. Nova metoda zaštite od korozije u uslovima kondenzacije je ispitivana u staklenoj ćeliji kao i u sistemu sa višefaznim tokom fluida, posebno konstruisanom za ispitivanje uticaja operativnih parametara na koroziju čelika u uslovima kondenzacije. Na osnovu dobijenih rezultata merenja vršenih u tečnoj fazi potvrđeno je da je inhibitor TOFA/DETA imidazolin dobar i efikasan inhibitor za koroziju niskougljeničnog čelika u rastvoru 3 mas. % NaCl zasićenom sa CO2 uz izmerenu vrednost efikasnosti inhibicije preko 92%. Pena sa TOFA/DETA imidazolinom efikasno smanjuje brzinu korozije čelika u gasovitoj fazi uz efikasnost inhibicije od oko 90 % i vreme trajanja izvedene zaštite od korozije do 50 h.

AB  - Innovative top-of-the-line corrosion (TLC) inhibition techniques are being investigated as an alternative to batch treatment. A novel idea consists of injecting the corrosion inhibitor within a foam matrix. Previously, a "proof of concept" validation of the novel TLC mitigation method was successfully conducted in a small-scale laboratory setup. The findings in this paper present the next step in the study before field trial: validation of the method and characterization of the foam properties in realistic, large-scale flowing systems. The foam containing the inhibitor was injected into the flow loop, forming a dense plug, which was pushed forward by the gas. The foam-generation method carried considerable importance for foam stability, as well as inhibition persistency. Foam created under stagnant conditions retarded the corrosion rate up to 97%, however the inhibition effect was not persistent. When the foam containing 20,000 ppmv of corrosion inhibitor, TOFA/DETA imidazoline, was created in flowing conditions, the corrosion inhibition efficiency was calculated to be higher than 90%, and the inhibition effect lasted up to 50 h. The novel TLC mitigation method showed promising results in a largescale flow loop, and applications in oil and gas field environments should be considered.

AB  - Top-of-the-line corrosion (TLC) has been a serious issue for the oil and gas industry. Conventional inhibition techniques are expensive and often do not seem to provide enough protection to the steel surface at the top of the pipe. A novel idea is to inject the corrosion inhibitor within a foam matrix. The foam slug is formed first at an injection port and carried along the pipe by the gas phase. This process ensures homogeneous delivery of the inhibitor to the pipe wall along pipe sections suffering from TLC. This paper presents a comprehensive study performed in an innovative glass cell setup which consisted of a foaming cell and a corrosion cell to simulate intermittent contact between the foam and the steel surface. Corrosion measurements were performed using electrochemical techniques (electrochemical impedance spectroscopy [EIS], linear polarization resistance [LPR], potentiodynamic sweep) and electrical resistance (ER) measurements to determine the inhibitive performance of investigated inhibitor talloil diethylenetriamine imidazoline (TOFA/DETA imidazoline) within a foam matrix (sodium C14-16 olefin sulfonate).

The foam was then injected into the flow loop, forming a dense plug which is pushed forward by the gas. This provided uniform delivery of the inhibitor to the inner pipe wall. Hydrodynamic tests in flow loop were performed in order to investigate the foam stability as a function of gas velocity as well as the effect of different foaming agent concentrations on the consistency and strength of the foam. Corrosion rate was monitored under condensing conditions using electrical resistance (ER) measurements. The TLC rate of mild steel, as measured in the wet gas flow using the ER probe, was reduced by periodic treatment using the optimized foam composition.

AB  - This paper presents a comprehensive method to evaluate a mixture of dicyclohexylamine and oleylamine (DCHA+OA) as a corrosion inhibitor for mild steel in a CO2 environment in the liquid and vapor phase. The volatile properties of the corrosion inhibitor were investigated in order to determine whether DCHA+OA could be used to control the severity of a top of the line (TLC) corrosion attack. Corrosion measurements were performed using electrochemical impedance spectroscopy, linear polarization resistance, potentio-dynamic sweep measurements, as well as electrical resistance and weight loss measurements, in order to determine the inhibitive performances of dicyclohexylamine and oleylamine. In order to define the surface morphological characteristics, the scanning electron microscopy technique was applied. The electrochemical study and the weight loss measurements indicated that DCHA+OA significantly decreased the corrosion rate in the liquid phase when 50 ppm of DCHA+OA was added. Scanning electron microphotographs indicated a protective inhibitor film was formed on the steel surface and revealed that good protection was achieved, together with a decrease in the corrosion rate, as determined by weight loss and electrochemical techniques. It was shown using electrical resistance measurements in the vapor phase, that a concentration of 1000 ppm DCHA+OA significantly decreased the corrosion rate at the top of the line only when it was carried there within its own foam and not due its volatility.

Isparljivost smese DCHA+OA je ispitivana u cilju potencijalne primene DCHA+OA kao lako isparljivog inhibitora za smanjenje brzine korozije u uslovima kondenzacije. Pri ispitivanju inhibitorskih svojstava smese diciklohekcilamina i oleilamina primenjene su sledeće tehnike karakterizacije: spektroskopija elektrohemijske impedancije, metoda linearne polarizacione otpornosti, metoda polarizacije linearno promenljivim potencijalom, merenje električne otpornosti, gravimetrijska metoda određivanja gubitka mase, kao i skenirajuća elektronska mikroskopija. Rezultati elektrohemijskih merenja i gravimetrijske metode određivanja gubitka mase pokazuju da dodata smesa DCHA+OA u koncentraciji od 50 ppm značajno smanjuje brzinu korozije u tečnoj fazi u odnosu na sistem bez inhibitora. Mikrofotografije površine čelika potvrđuju da se u prisustvu smese DCHA+OA smanjuje stepen korozije kao posledica formiranja zaštitnog filma inhibitora na površini niskougljeničnog čelika. Primenom tehnike merenja električne otpornosti u gasovitoj fazi pokazano je da dodatak smese inhibitora DCHA+OA u koncentraciji od 1000 ppm dovodi do značajnog smanjenja brzine korozije u uslovima kondenzacije, samo u slučaju kada se transport inhibitora do površine čelika ostvaruje u obliku pene, a ne zbog isparljivosti samog inhibitora.

AB  - Top of the Line Corrosion (TLC) has been a serious issue for the Oil & Gas industry. Conventional inhibition techniques are expensive and often do not seem to provide enough protection to the steel surface at the top of the pipe. A novel idea is to inject the corrosion inhibitor within a foam matrix. The foam slug is first formed at an injection port and carried along the pipe by the gas phase. This process ensures homogeneous delivery of the inhibitor to the pipe wall along pipe sections suffering from TLC. This paper presents more comprehensive study performed in an innovative glass cell setup which consisted of a foaming cell and a corrosion cell in order to simulate intermittent contact between the foam and the steel surface. Corrosion measurements were performed using electrochemical techniques (EIS, LPR, potentiodynamic sweep) and electrical resistance (ER) measurements, in order to determine the inhibitive performance of investigated inhibitor talloil diethylenetriamine imidazoline (TOFA/DETA imidazoline) within a foam matrix (sodium C14-16 olefin sulfonate).
