Carbon capture and storage (CCS) or utilisation (CCU) of the captured carbon dioxide (CO2) are tools for reducing global carbon emissions, and to combat climate change both are required. According to the IEA1, in 2021, the global capacity of CCS grew by 48%i, showing that this technology is becoming more popular to meet sustainability targets.

Safe and stable operation of the process plant through its life cycle is an ultimate target of any integrity management system. Over the last decades, a number of possible ways and systems for managing plant integrity were described and implemented.1-4 A common path for all those efforts was to control and manage corrosion processes in a more-or-less systematic way by applying certain measures (monitoring techniques, material selection guidelines, operating procedures etc.) and performance indicators (remaining time-to-failure, inhibitor usage etc.). An effective corrosion and integrity management system, in theory, should be capable to “uncover” excessive corrosion incidents before serious damage occurs. Unfortunately, unexpected corrosion-related failures are still occurring in the petroleum industry.5 This situation stems predominantly from relatively poor data organization and management, leaving corrosion and key process information spread and hidden across different refinery functions and systems.
Microreactor technology has the potential to provide efficient, modular, and inherently safe baseload power that can be used in regions that are too remote to support the larger, light water reactor (LWR) technology that dominates today’s nuclear energy landscape. To generate enough power and thermal efficiency to be attractive, the microreactors must be operated at higher temperatures (approximately 1112-1652°F or 600-900°C) than traditional LWR’s, and therefore are cooled using technologies such as heat pipes with gas, sodium, or molten salt coolants.
AM brings significant benefits in better performance, inventory management, and lifecycle cost reduction to the Oil & Gas industry. Both manufacturers and users are working towards AM qualification and standardization in order to realize and sustain these benefits. Starting at the product level, the goal is to ensure the product is sound in its form, fit, and function, and free from macroscopic (surface, sub-surface, internal) anomalies deleterious to its performance. Product qualification is supported by a foundational metallurgical or AM material qualification.1
Oil and gas operations are pushing the limits of Sour Service always further with the need to combine high Sulfide Stress Cracking resistance (SSC) in H2S partial pressure while keeping high levels for Specified Minimum Yield Strength (SMYS). Operators are indeed entering into new drilling challenges when targeting complex well formations where production casings could be exposed to Sour Service environment and tubing completions to increased differential pressure. Having high levels for Specified Minimum Yield Strength (SMYS) paves the way for addressing Multi-Stage Fracturing (MSF) developments that reach pressure differentials as high as 15,000psi during fracturing operations in challenging environments with minimum intervention possibilities.
TGTU is one of the most versatile units in sulphur complex that will help in achieving sulphurrecovery up to 99.9% and reduce the SO2 emission to the atmosphere.
Carbon capture and storage (CCS) are technologies aimed at capturing CO2, followed by transportation to a storage site and injection into one of several types of stable geological formations, to trap and prevent its subsequent emission. Though CO2 transport and injection for Enhanced Oil Recovery (EOR) are known for over 40 years, new challenges arise when the CO2 source is anthropogenic, meaning with a human-cause origin and not natural (as in EOR). EU Directive 2009/31/EC states that CO2 streams from power stations or industrial plants "shall consist overwhelmingly of CO2" but may contain associated incidental substances (e.g., SOx, NOx, O2, H2S).
The goal of the Paris Agreement is to limit global warming to below 2°C, preferably 1.5°C, compared to pre-industrial levels.1 While the world is slowly transitioning to more sustainable energy sources to reach this target, one of the ways to reduce the CO2 in the atmosphere is to capture it and store it in depleted gas fields. According to the IOGP1, the total number of CCS projects in Europe is 65 in 2022.2 The aim of these projects is to store around 60 MtCO₂/yr by 2030.
This paper will provide recent corrosion data for stored chemicals. Duplex stainless steel corrosion curves obtained in nitric, sulfuric, phosphoric acids as well as several kinds of waters will be provided. In addition, atmospheric corrosion data obtained after 15+ years of sample exposures in several geographic areas will be shown. These results will be compared to those obtained with other materials commonly used for the construction of storage tanks.
