A Parametric Evaluation of Well Construction Corrosion-Resistant Alloys for Geological Carbon Sequestration

A parametric test program involving completion alloys in supercritical CO2 was conducted using both isothermal and non-isothermal cycles in the presence of contaminants (i.e., H2O, NO2, SO2, H2S, H2) above typical impurity limits for carbon capture and sequestration (CCS). The isothermal testing consisted of 4500 psi (310 bar) autoclave tests at 175°F (79°C) with the test materials in supercritical CO2, and optionally, in a NaCl-rich brine in equilibrium; the non-isothermal testing was similar, but included three consecutive cycles with 250°F (121°C) and 70°F (21°C) exposures. Up to ten corrosion-resistant alloys [i.e., 9Cr (UNS K90941), 13Cr (UNS S42000), S13Cr (ISO13680 (1) Type 13-5-2), 15Cr (proprietary), 17Cr (proprietary, 22Cr (UNS S32205), 25Cr (UNS S32750), G3 (UNS N06985), 925 (UNS N09925), 718 (UNS N07718), and 716 (UNS N07716)] were tested for weight loss, pitting, and crevice corrosion. The alloys, known to be more susceptible to environmentally-assisted cracking (EAC), were also evaluated for cracking with ppm-levels impurities (25-to-150 ppmv each), including hydrogen sulfide (H2S). Alloys 22Cr, 25Cr, and API (2) Spec. 6A and Std. 5CRA nickel-based alloys are generally found to be fit-for-service for subsurface CCS. In contrast, the alloys with 9-to-17 wt.% chromium tend to suffer from pitting, which when extensive, has been associated with a case of EAC. For the pitting-resistant alloys under test, neither EAC nor crevice corrosion created major new risks. The introduction of non-isothermal cycles to qualify alloys for CCS has successfully emphasized the dominant effects of condensates, otherwise under-represented, and is suggested for future material testing and qualification programs.

An Evaluation of Well Completion Materials for Impure Carbon Dioxide Supercritical Streams in Hydrocarbon Production and Geological Carbon Sequestration

Product Number: MECC23-20034-SG

Author: Manuel Marya

Publication Date: 2023

Carbon capture and storage (CCS) represents to traditional industrial emitters a critical transitional technology to globally manage greenhouse gas emission, meet the latest carbon net-zero ambitions, and continue the commercial use of fossil fuels. In CCS, anthropogenic CO2 is captured near emission, treated, compressed, transported (usually by steel pipelines), injected underground through casings, tubings, and completion equipment, and finally permanently stored into saline formations, aquifers, depleted (abandoned) reservoirs, or un-mineable coal seams. [1] Depending upon emitters, the injected CO2 is either near or in a dense state (i.e., indistinctly including a supercritical phase and potentially liquids) having various impurities.

CO2 Transport and Injection, Effect of Impurities, Understanding of Reactions and Consequences

The effect of CO2 concentration in the atmosphere on temperature has been known for a long time. Although an increase in CO2 concentration has been observed since the 1960s, a clear change in trend of global temperature increase can be observed from around the 1990s. CCS (Carbon Capture and Storage) is a mature technology available to reduce emissions from large scale fossil-based energy and industry sources. Sufficient geological storage is available for these sources. Mitigation of CO2 emissions via CCS has been identified as crucial to limit global warming.3 In recent years a significant increase in CCS projects have been proposed and initiated.

Compatibility Of Steels At 450°-650°C In Supercritical CO2 With O2 And H2O Additions

Product Number: 51322-18018-SG

Publication Date: 2022

$20.00

Using supercritical CO₂ (sCO₂) as a working fluid is being explored for a number of power generation technologies including fossil, nuclear, geothermal, concentrating solar power (CSP) and waste heat recovery^1-7. The various sCO₂ cycles are attractive because of the low critical point (31°C/73.8 bar) and the reduced work of compression compared to an ideal gas. While CO₂ is sometimes described as inert, there is a long history of component degradation in subcritical and supercritical CO₂ and a particular concern about internal carburization^8-16.

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).

Vital work is being carried out across engineering to ensure the net-zero commitments as laid out in the Paris agreement are met. Due to increased government investment, carbon capture, utilisation, and storage (CCUS) has become key to achieving these commitments, with some industries only able to decarbonise through CCUS, such as concrete or fertiliser production. Carbon capture has also moved away from vertically integrated systems, with single emitters having dedicated downstream transport and storage sites, to larger systems gathering CO2 with a shared transport and storage infrastructure.

Publication Date: 2023

Supercritical CO2 (sCO2) has many attractive features as a working fluid including its low critical point (31°C/73.8 bar) and the reduced work of compression compared to an ideal gas. Thus, it is being explored for many different applications including fossil, nuclear, geothermal, concentrating solar power (CSP) and waste heat recovery. However, CO2 environments are known to carburize steels6-20 which limits their usage to lower temperatures (450°C21 for 9%Cr steels) than in steam boilers.

A dense phase or supercritical CO2 pipeline is a crucial state in the oil and gas sector, particularly when it comes to enhanced oil recovery (EOR) and carbon capture and storage (CCS)1. The process of CCS involves three stages: capture from sources (e.g., cement factories and power plants), transportation process, and storage. Generally, these pipelines carry CO2 from different industrial facilities to geological formations.

SCC Of Alloy 82 Weld Metal In BWR Water

Product Number: ED22-17242-SG

Author: Peter L. Andresen, Katsuhiko Kumagai

Publication Date: 2022

$20.00

There is extensive evidence from laboratory data and plant experience of the SCC susceptibility of Alloy 82 weld metal in both BWR and PWR environments. Two international expert panels evaluated laboratory data under PWR conditions and created disposition curves to address the effects of stress intensity factor (K), temperature, and other factors. Another expert panel is creating a disposition
curve under BWR conditions for K, temperature, corrosion potential, impurities, and other factors. Nickel alloy weld metals at lower Cr levels (~15% Cr for Alloy 182 and ~20% Cr for Alloy 82) are more susceptible to SCC than weld metals of higher Cr content (~30% Cr for Alloy 52/152). This paper focuses on on-thefly effects on SCC growth rate of Alloy 82 weld metal in BWR environments of corrosion potential, water
purity and temperature.
