“…Moreover, the cathodic reaction, involve oxygen in neutral or alkaline solutions can be expressed as follows [34]: In the presence of oxygen, the aqueous corrosion mostly likely formed the oxyhydroxides: α-FeOOH, γ-FeOOH, akageneite (β-FeOOH) and Fe 2 O 3 [13]. Corrosion occurred via metal dissolution as an anodic reaction: …”

“…According to the reported literature, more than 99% of adhered bacteria on the solid surface could be killed under available chlorine ranging from 50 to 100 ppm [11]. The biocidal mechanism of available chlorine is due to its reaction with organic and inorganic components, inactivate microbial cells and oxidise nutrients [12,13]. However, the available chlorine affected by impurities or light in the water can produce hypochlorite, which is among the most corrosive of chemicals [14].…”

Available chlorine is known to play a significant role in metal corrosion due to its oxidising properties. In this paper, the effect of available chlorine concentration on corrosion behaviour of the low alloy marine steel was investigated by electrochemical and immersion tests. Experimental results show that the corrosion rate of low alloy marine steel is accelerated with the increase of available chlorine concentration in seawater. The localised electrochemical dissolution of the steel is more active with the concentration of available chlorine increasing. Energy dispersive spectroscopy (EDS) was performed to understand the composition of the corrosion products that the large enrichment of Cl element occurred for the high available chlorine concentration (100 ppm) after 720 h exposure to seawater. The influence of available chlorine concentration on mechanical property of low alloy marine steel indicatesthe less impact on the tensile and yield strength of the low alloy marine steel.

“…This was reported Nordin et al: Electrochemical Degradation of Reactive Blue 21 ... by several researchers in previous studies. [26][27][28] According to Galvan-Martinez et al, 26 OClions are corrosive to some elements. This resulted in the corrosion of Co 47.5 / C 47.5 -PVC 5 electrode surface after electrolysis of RB21 by using NaCl electrolytes.…”

In this study, cobalt/graphite-polyvinyl chloride (Co 47.5 /C 47.5 -PVC 5 ) composite electrode was fabricated by mechanical alloying technique. The fabricated electrode and graphite rod were used as anode and cathode, respectively, in the decolourisation of aqueous C. I. Reactive Blue 21 (RB21) and synthetic textile effluent, containing a mixture of azo and anthraquinone dyes. The fabricated electrode showed high efficiency in the decolorisation of aqueous RB21 (99.95%) and synthetic textile effluent. This is further confirmed by the high reduction percentage (>75%) of COD and BOD 5 for both treated samples. The elemental composition study by using FESEM-EDX showed no significant changes in the composition of elements (C, Co and Cl) in the freshly fabricated electrode and after electrolysis of synthetic textile effluent. This showed that the fabricated electrode has a high mechanical strength and strong binding ability between C and Co due to the use of PVC as a binder.

“…In the abiotic system, the corrosion rates were higher with a maximum value of 5.0782 mm/ year after 200 hours of testing. Oliveira et al 30 investigated the corrosion rate by weight loss of carbon steel SAE 1010 after 28 days of immersion in seawater with and without sodium hypochlorite. The results showed high corrosion rate in the seawater system (control), while in the seawater with sodium hypochlorite system there was a reduction of the corrosion rate and the existing microorganisms.…”

Corrosion Behavior of API 5L X80 Steel in the Produced Water of Onshore Oil Recovery Facilities

et al. 2017

High-strength low-alloy steel is used in pipelines, which transport oil/gas and also produced water in the process of the secondary recovery of oil. This paper investigates the corrosion of X80 steel after immersion in static systems (biotic and abiotic). The corrosion rate, the corrosion morphology and the hardness of the coupons were investigated. The corrosion products were determined by SEM/EDS and XRD. The corrosion rates of the coupons in the biotic system were moderate and had an agressive pit morphology, while those of the coupons in the abiotic system were low with less aggressive pit. The hardness of the coupons after exposure to the systems of produced water was not changed compared with that of the control coupons. The corrosion products formed in the biotic system were Fe(OH) 3 , Fe(OH) 2 , FeOOH, Fe 3 O 4 , FeS 2 , FeCl 3 , and in the abiotic system, NaCl, CaCl 2 and SrSO 4 . BaSO 4 and CaCO 3 were identified in both systems.
