Corrosion Of 2Cr Steel In Supercritical CO2 Saturated Saline Water With Cl, S and Br Anions

Before full decarburization can be achieved, the Intergovernmental Panel of Climate Change (IPCC) suggests an applicable way of combining CO2-producing processes with the carbon capture, utilization, and storage (CCUS) chain. Except for permanent CO2 storage, the economics and efficiency of CCUS processes can be further improved by utilizing the CO2 byproduct in other industry areas. One of the promising methods is to use the captured CO2 for enhanced oil recovery (EOR).

In the context of urgent efforts to reduce global carbon emissions, carbon capture, utilization, and storage (CCUS) has gained prominence. Tubing and casing steels are vital materials of construction (MOC) in CCUS systems, especially in supercritical CO2 (s-CO2) environments. However, the understanding of the corrosion behavior of these steels under s-CO2 conditions is limited, which presents integrity challenges. Immersion experiments were conducted with steels containing varying chromium (Cr) levels (0.5 wt% to 16.5 wt%), including P110, P91, and SS 316. These steels were exposed to s-CO2-saturated brine water (3.5 wt% NaCl) at 50 °C and 10 MPa for durations of 10 and 100 hours. Corrosion rates were determined via weight loss measurements, and corrosion products were analyzed with SEM and XRD. P110 displayed the highest corrosion rates (15.7 mm/y at 10 hours, 2.9 mm/y at 100 hours) but developed a thick FeCO3 layer after 100 hours. In contrast, P91 and SS 316 exhibited lower corrosion rates after 100 hours (0.04 mm/y and < 0.01 mm/y, respectively). The influence of Cr content and exposure duration on the corrosion behavior of these steels were discussed. All steels exhibited decreasing corrosion rates over time, primarily due to oxide formation, enhancing the understanding of casing and tubing steel corrosion in s-CO2 environments.

Carbon nanotubes are well-known for their ability to improve critical properties of polymeric materials. Our research objective is to quantify the influence of incorporating multi-walled carbon nanotubes (MWCNT) modified with amine, hydroxyl, or epoxy functionalities on the corrosion performance of epoxy amine coatings on steel substrates.

Cyclic Polarization and Electrochemical Impedance Techniques to Rapidly Screen and Assess Pitting Tendencies of Corrosion Inhibitor Actives in Carbon Steel

Product Number: 51323-19389-SG

Author: Yolanda De-Abreu, Ana Ferrer, Geeta Rana, Sherman Kung

Publication Date: 2023

$20.00

Corrosion inhibitors (CI) are typically evaluated using either short-term electrochemical methods or long-term weight loss methods in laboratory set up. Although electrochemical methods provide fast and real-time corrosion information, corrosion subject matter experts, in general, rely on long term weight loss methods to determine localized corrosion information. These long-term methods include exposure of the metal coupon in a corrosive media under specific field conditions/parameters such as temperature, pressure, wall shear stress, corrosive gas species and test length in the presence of corrosion inhibitor active(s).

Determination of the Corrosion Rate of Thermally Spayed Aluminum (TSA) in Simulated Marine Service

Product Number: 51320-14650-SG

Publication Date: 2020

Operators desire extended life of offshore facilities, structures and components to improve affordability, and to increase their availability in later years of operation. Whilst maintenance and replacement of topside facilities is possible, critical to this objective is the design and construction of supporting infrastructure and facilities capable of withstanding splash and tidal zone corrosion for the lifetime of the structure with minimum maintenance.

Thermally sprayed aluminum (TSA) is increasingly applied in marine environments as a corrosion mitigation solution but few studies provide quantitative corrosion rate data, from which a lifetime of little or no maintenance can be predicted. A technology review was undertaken to establish current working practice and experience related to the mitigation of splash and tidal zone corrosion. A number of coating systems (thermally sprayed, organic paints and duplex combined thermal spray and paint), currently used in the splash and tidal zone of offshore structures, were identified. Thermal spray coatings with and without aluminum-silicone sealant were prepared and tested in alternate immersion using linear polarisation resistance (LPR) methods. The data were analysed and corrosion rates values were obtained.

The work here is the culmination of many years of prior effort in the development of an atmospheric corrosion model and accompanying sensors. Atmospheric corrosion is a complicated process where many factors interact to determine if it occurs and its severity. These factors can be separated into
three general categories: environmental, surface salts, and materials.

Effect of Flow Velocity on the Corrosion Performance of Thermally Sprayed Aluminium Coating in Synthetic Seawater

Product Number: 51324-20835-SG

Author: Adriana Castro Vargas; Shiladitya Paul

Publication Date: 2024

This work focuses on the effect of flow velocity on the corrosion performance of Thermal Spray Aluminium (TSA) Coating obtained by twin-wire arc spraying. Cylindrical electrodes (12 mm diameter) were machined from an S355 steel rod and coated with 300 µm thick TSA (AA 1050). An analytical rotator was employed for testing the coupons at 50 rpm and 600 rpm for 10 d in synthetic seawater. Testing under stagnant conditions was also included. Open Circuit Potential (OCP) and Linear Polarisation Resistance (LPR) measurements were carried out at 18 ±2 °C to assess the flow velocity effect and calculate the corrosion rate. Within 5 days of immersion, the OCP became more positive at higher rotation speeds. White corrosion products and calcareous deposits were observed on the coupon surfaces after 5 days, and the corrosion rate decreased in all cases.

A 2002 study estimated the annual cost associated with corrosion of gas pipelines to be around $5 billion. Corrosion of oil and gas pipelines continues to pose a major issue in the oil and gas industry due to the combination of brine produced with the oil and the type of acid gas present which can lead to significant internal corrosion. Oil and gas reservoirs can be separated into two categories, sweet and sour.

Electrochemical Methods vs Long-Term Immersion Tests to Assess Localized Corrosion Tendencies of Corrosion Inhibitors (Phase II)

Publication Date: 2023

Electrochemical methods have long been utilized to provide real-time corrosion information but have rarely been used to study localized corrosion. Most recently, electrochemical methods such as electrochemical impedance spectroscopy (EIS) and cyclic polarization (CP) were investigated to predict pitting tendencies and the work was presented in 2022.

Based on this work, it was proved that CP technique can be used to predict localized corrosion tendency of continuous corrosion inhibitors.
