This paper studies the effect of oxygen in methanol on the structures and growth kinetics of iron sulfide scales. Gravimetric weight analysis was used to evaluate the corrosion mechanisms and rates. Scanning Electron Microscope/ Energy Dispersive X-ray Spectrometry (SEM/EDX), Optical Microscope and X-ray Diffraction (XRD) were used to analyze the scale.
Case histories are presented where Oxygen ingress has led to Sulfur corrosion failures in pipelines and downhole equipment.
A polyamide 12 (PA12) material has been specifically engineered. After laboratory testing, a significant project was developed to install PA12 in a sour, multiphase, pipeline. Material qualification program is discussed. Performance of the liner in service and inspection of test coupons are described.
In this work, both planar electrode and 1-dimensional (1D) artificial pit experiments were performed The effects of deposit chemistry and morphology on the electrochemical dissolution behavior are discussed in terms of a transport-controlled model for pit propagation.
The focus of this paper is the welding metallurgy and weld metal properties of N07022 alloy. Evaluation of the N07022 weld metal microstructure will be discussed. Sour gas testing of N07022 weld overlay material will be highlighted. Mechanical properties will be presented.
A sour gas plant was experiencing high corrosion and fouling in aggressive conditions (170 to 195°F, 170 psi pH2S, 280 psi pCO2) including the presence of elemental sulfur (0.1 wt%). The current chemical program appeared to be ineffective.
Carbon dioxide capture, utilization, and storage (CCUS) is part of decarbonization solutions to reduce green-house gas emissions, as exemplified by the growing number of capital expenditure projects worldwide.1-2 In CCUS, the carbon dioxide (CO2) is consecutively (1) captured at origin, such as power plants and natural gas production sites, (2) separated from other gases and impurities, (3) compressed, (4) transported through pipelines, and finally (5) injected into a storage site such as deleted hydrocarbon wells, saline aquafers, coal beds, underground caverns, or seawater.1,3 Since the 1970s, specifically the first commercial carbon dioxide flooding in the United States (known as SACROC), carbon dioxide sequestration has been largely discussed in the context of enhanced oil recovery (EOR), not in the newer context of Sustainability. Nonetheless, substantial experience has been drawn from EOR, including for the selection of the right and economical materials.4 As reflected by the literature, past materials test programs have rarely given any attention to downhole jewelry alloys compared to tubulars or surface-infrastructure alloys, and consequently the track records for such bar-stock alloys are either inexistent or not readily available. 5-7 This lack of apparent return-on-experience represents a knowledge gap against the prospect of a safe greenhouse gas control method; needless to say, it also justifies the requirements for reliable well integrity monitoring solutions in carbon dioxide sequestration wells.8-9
Application of sour linepipes has expanded toward severe sour environment regions including higher H2S partial pressure conditions. In 2013, actual sour gas pipeline failure occurred due to SSC (Newbury et al., 2018). One of the possible root cause of SSC was assumed to be a formation of hard spots in asurface region of steel. Fairchild et al. investigated and proposed three hard zone formation mechanisms including carbon contamination, dual phase microstructure and heat transfer variation in a recent paper (Fairchild et al., 2019; Newbury et al., 2019).
Failure of a diffuser (with vanes, made from material P265GH) is investigated. The gas compressor was in service for over 10 years. The gas contained both CO2 and H2S. Relative humidity of the gas was 100 %. It was found that the diffuser was fractured in 3 locations.
Recent results of sour gas and hydrogen embrittlement testing of CW N07022 alloy will be presented. The test results of CW N07022 alloy will demonstrate that it offers superior properties to precipitation-strengthened Ni-base alloys for demanding oil and gas applications.
