Advancement of a Comprehensive Mechanistic CO2 Corrosion Model to Incorporate Simulated Hydrodynamics via a Turbulent Flow Model

Product Number: 51324-20657-SG

Author: Michael Jones; Gregory de Boer; Richard Woollam; Joshua Owen; Richard Barker

Publication Date: 2024

$40.00

In this work, two comprehensive mechanistic models of aqueous carbon dioxide (CO2) corrosion produced by Nordsveen et al.1 and Kahyarian et al.2 17 years apart are recreated and compared to highlight the evolution in understanding. The differences between the models include the role of carbonic acid at the surface, whether it is directly reduced or acts as a buffering agent, as well as different mechanisms for the anodic response, and varying temperature responses of multiple input variables. Through recreation and validation of these models using the same software, key comparisons are made to understand the effect of these changes on predicted corrosion rate, surface pH, and speciation through the boundary layers. These values are plotted across a range of input parameters to investigate how the change in scientific understanding influences predictive response of corrosion models.

An Exploratory Investigation of the Cracking Susceptibility of Three Corrosion Resistant Alloys under Thermal Cycles and Conditions Exceeding the Traditional NACE MR0175/ISO 15156 Recommendations

Product Number: 51324-20455-SG

Author: Manuel Marya

Publication Date: 2024

$40.00

The environmentally-assisted cracking (EAC) of three wrought corrosion-resistant alloys (CRAs) with a minimum yield strength of 110ksi (760MPa) was investigated between 70°F (21°C) and 450°F (232°C) through weekly thermal cycles totalizing 42 days. The thermal cycling was introduced to approximate service equipment conditions and gain additional confidence on the EAC-free limits of all three CRAs. Alloys 17-4PH, K-500, and 925 were selected and exposed to a 180,000-ppm NaCl brine (pH=2.75) in equilibrium with 1000 psi (68.95 bar) H2S, 1000 psi (68.95 bar) CO2, and 2500 psi (172.37 bar) CH4. All three CRAs were (a) acquired as per the NACE MR0175/ISO 1516 requirements (1), (b) tested as per NACE TM0177 Method C at 30-to-90% of the CRA minimum specified minimum yield strength (SMYS), and (c) also compared for their weight-loss corrosion and localized corrosion. The results show: (a) Alloy 17-4PH remains resistant to EAC below 45% of its SMYS, (b) Alloy K-500 resists cracking at an estimated 80% of its SMYS, but uniformly corrodes by sulfide conversion under film at a rate of 64 mpy (1.63 mm/yr.), and (c) Alloy 925 continues to be immune to EAC at 90% of its SMYS. Alloy 17-4PH also corroded at a rate of 22.8 mpy (0.58 mm/yr.) in comparison to only 0.6 mpy (15.2 mm/yr.) for Alloy 925, with no CRA showing experiencing crevice corrosion.

Distribution of Corrosion Attacks in Sour Pipelines – A Parametric Study

Product Number: 51323-18981-SG

Author: Abdulrahman Alqahtani, Layan AlSharif, Faisal Abbas, Christian Canto Maya

Publication Date: 2023

$20.00

In pipeline corrosion management practice, one challenge is how to locate the most corrosive area along the right-of-way of an existing pipeline. Pipeline networks are complex systems containing different grades of multiphase crude oil coming from dissimilar reservoirs, which results in fluids having dissimilar chemical and physical properties along each network. The fluid starts flowing into a pipeline at a certain pressure, temperature, and associated velocity.

H2S corrosion, also known as sour corrosion, is a very serious type of metal degradation in oil and gas transmission pipelines. When H2S is present in an operating pipeline, localized corrosion is the type of attack which contributes to the most failures in oilfields, consequently, its impact on the economics of oil and gas production is indisputable. Therefore, mitigation of this type of corrosion could prevent such failures and significantly enhance asset integrity while reducing maintenance costs as well as eliminating environmental damage.

Hydrocarbons still remain as a fundamental contributor towards meeting the worldwide demand for energy, despite the growth of other alternative sources such as renewable and nuclear options. Due to low cost and availability, carbon steel, remains as the most commonly used material for pipelines in down and upstream activities within the oil and gas industry. However, carbon steel is not an exceptional metal alloy from the perspective of internal corrosion resistance. The economical cost for its degradation and related failures represent 10% to 30% of the maintenance budget in petroleum industry. It is therefore crucial that the corrosion of such a susceptible steel is managed and controlled accordingly.

Internal Corrosion of Flare Header - A Case Study

Product Number: 51324-21201-SG

Author: Ayman A. Alabdullatif; Lay Seong Teh; Hatam Mehraz; Anaam H. Shaikh Ali

Publication Date: 2024

$40.00

In a major gas-oil separation plant (GOSP) in Saudi Arabia, a major flare header suffered from severe internal corrosion. Upon analyzing the scale and sludge that was found accumulated in the line, a significant proportion of elemental sulfur was identified. This indicated that in addition to hydrogen sulfide and water (which were expected to be present in the line), significant amount of oxygen was also present. An investigation was conducted to identify the source of this oxygen and to eliminate it. Other critical factors that impacted the internal corrosion were also identified. The line was not properly sloped to drain accumulated moisture. Knock-out boot levels were often high and not regularly drained. In addition, purge gas was not operated at rates adequate to sweep any accumulated liquids. All of these factors combined led to an accelerated deterioration of the header.
