A lot of oil and gas facilities face corrosion problems because the production fluid contains some corrosive components represented by CO₂. Generally, corrosion inhibitors are used in order to mitigate corrosion problems of tubing and pipeline. Imidazoline is known as one of the active ingredients of corrosion inhibitors and widely used in the oil and gas industries. However, imidazoline-type inhibitor is easily hydrolyzed to amide if water mixes into it.

In hydrocarbon production systems, mild steel is overwhelmingly used for the construction of pipelines and tanks for the transmission and storage of crude oil, natural gas, and derived petroleum products. Although mild steel has excellent mechanical properties and low cost, it is susceptible to corrosion attack in typical service environments. Inhibition of internal corrosion is essential for assuring asset integrity of oil and gas transportation pipelines.

Effect of Ni on Sulfide Stress Cracking and Stress Grooving in Carbon Steel - Part 1: Constant-load (Dead-weight) Test

Product Number: 51324-20715-SG

Sulfide stress cracking (SSC) occurs in steel exposed to sour environments. Ni promotes the formation of a crack-like corrosion morphology (so-called stress groove or fissure), which accelerates the SSC; however, the mechanisms underlying fissure formation and growth are not fully understood. In this study, the effects of Ni on SSC and fissures were investigated. Constant-load tests were conducted at various potentials using TS 800 MPa grade steel with and without 1 % Ni addition. The fissures were formed near the corrosion potential on adding Ni. Anodic or cathodic polarization promoted SSC, suggesting that SSC was affected by both active path corrosion (APC) and hydrogen embrittlement (HE) mechanisms. In addition, the fissure shapes and crystal orientations of the microstructure were analyzed to classify the fissures as dissolution (corrosion) or mechanical cracking. Further, characteristic grooves promoted by Ni were confirmed to be APC.

Four point bend sulfide stress cracking (SSC) tests were carried out under various conditions of H2S partial pressure, pH, soaking time, and applied stress to investigate the formation of stress groove (or fissure) and SSC behavior in TS 800 MPa (116 ksi) grade steel plates with 1%Ni added and 0% Ni steels. Under low hydrogen sulfide (H2S) partial pressure conditions, a fissure was formed only in the 1%Ni steel, although no SSC occurred. Morphology of the fissure in 1% Ni steel indicates that fissure extends by a corrosion, which is also called the anodic dissolution or the active path corrosion (APC). The fissure in 1%Ni steel grew almost linearly with soaking time in the test solution with stabilized pH condition. Formation and growth of fissure was enhanced by higher applied stress and there was a limiting stress for the formation of fissure. SSC occurred in both steels under high H2S partial pressure and low pH conditions. Detailed metallographic investigation for SSC cracks revealed that a corrosion pit initially formed then turned into a crack possibly by hydrogen embrittlement (HE), then finally caused unstable crack extension to rapture the specimen. Based on the experimental results for the fissure formation and SSC, the effect of both APC and HE are discussed.

Due to the increase in world’s population and technologies, and the limited fossil fuel reserves, efforts have been taken to seek alternative energy resources, such as bioenergy that is produced from renewable biomass, to meet the increasing need for energy. The feedstocks for bioenergy production can include the waste biomass from forestry and agricultural sectors and various industries such as food processing industry and pulp and paper industry, making a profit while saving costs from waste management.

Effect of Residual Copper, Nickel, and Chromium on the Corrosion Resistance of Carbon Steel in Hydrofluoric Acid Alkylation Services

Product Number: 51393-93623-SG

Author: H.H. Hashim, W.L. Valerioti,

Publication Date: 1993

Carbon steel is the main construction material in HYDROFLUORIC ACID (HF) alkylation units. Carbon Steel has good corrosion resistance to anhydrous HF (AHF) below 160 degrees fahrenheit (71 C). The corrosion resistance is due to the formation of an inorganic iron fluoride scale on the carbon steel surface that protects the steel from futher corrosion. The presence of an adherent and continuous scale is essential in keeping the corrosion rate at a minimum.

Electrochemical Corrosion Behavior of Carbon Steel With and Without Residual Elements

Product Number: 51320-14245-SG

Publication Date: 2020

Residual elements (RE) in carbon steel, not specifically included in the specified steel, appear to influence the corrosion rate under certain conditions, especially in services involving hydrofluoric acid (HF). The relative proportions of RE, specifically %C, %Ni, %Cu, and %Cr in carbon steel base and weld metals used in refineries, especially in alkylation processes with HF as the catalyst, significantly impact corrosion behavior. Studies described in the literature show corrosion damage with high RE (Cu + Ni + Cr >0.20) components as compared to low RE (Cu + Ni + Cr <0.20) components.

In this study, electrochemical corrosion testing was performed on a 3-inch pipe elbow section with high REs that had developed a through-wall leak in service. Test results were compared to those obtained on a similar pipe elbow section with lower REs. The samples were exposed to 50% HF at room temperature and at 65°C. Linear polarization resistance (LPR) corrosion rates were measured at both temperatures. Potentiodynamic (PD) polarization scans were performed on samples of low and high RE steel exposed to 50% HF at room temperature.

Test results indicated that LPR corrosion rates were higher for the high RE carbon steel samples than for low RE carbon steel samples at both temperatures. PD scans showed that the critical current densities were higher for high RE steel than for low RE steel.

Biocides are used to control problematic microorganisms in the oil and gas industry. High doses of biocides cause environmental and operational problems. Therefore, using biocide enhancers to make biocides more effective is highly desirable. 2,2-dibromo-3-nitrilopropionamide (DBNPA) is a popular biocide because it is broad-spectrum, effective, kills microorganisms immediately upon addition, and it degrades rapidly. D-amino acids are natural chemicals that have been used in lab tests to enhance biocides to treat biofilms. In this work, D-tyrosine was used to enhance DBNPA against Desulfovibrio vulgaris biofilm on C1018 carbon steel. After 7 days of incubation, the weight loss of coupons without treatment chemicals in culture medium was found to be 3.1 ± 0.1 mg/cm2. With a treatment of 150 ppm (w/w) DBNPA, the weight loss was reduced to 1.9 ± 0.1 mg/cm2 accompanied by a 1-log reduction in the sessile cell count. The combination of 150 ppm DBNPA + 1 ppm D-tyrosine achieved an extra 3-log reduction in sessile cell counts and an additional 30% reduction in weight loss compared with 150 ppm treatment of only DBNPA. The combination also led to a smaller maximum pit depth. Linear polarization resistance (LPR), potentiodynamic polarization and electrochemical impedance spectrometry (EIS) tests corroborated the enhancement effects.

Enhanced Oil Recovery: Localization of corrosion during polymer flooding

Product Number: 51323-18888-SG

Author: Moritz Schwingenschlögl, Gunther Ball

Publication Date: 2023

Traditionally, oil recovery operations are subdivided into primary, secondary and tertiary stages. EOR is commonly classified as tertiary recovery, where gases, liquid chemicals and thermal energy can be used to enhance the displacement of reservoir fluids. Different sources divide EOR into two to five categories, one particular method, polymer flooding, is based on increasing the fluid viscosity by adding a polymer to the injected water. Polymer EOR is a mobility-control process using a polymer-augmented waterflood, typically a solution of partially hydrolyzed polyacrylamide (HPAM) or polysaccharides, which is injected to displace oil towards production wells.
