Understanding the resistance of different grades of stainless steel to crevice corrosion , stress corrosion cracking , and de-passivation caused by chlorides , oxygen , and high temperatures is crucial when supplying materials for use in CCUS projects .
Upset conditions experienced by the pipeline , such as loss of process control , small leaks , shut-ins , or sudden decompression , can lead to the formation of acids resulting from impurities when pressures and temperatures change . Additionally , the boundary between the bulk stream and the injection well is likely to experience a large multi-phase boundary , which can cause formation water to wet the wellhead .
In case of a long-term shutdown , this can lead to extensive backflow of formation water . Therefore , it is essential not to rely on existing material standards for environments containing H 2
S or CO 2 when selecting materials for CCUS projects that involve CO 2 streams with impurities such as O 2 , NO 2
, SO 2 , CO , and H 2
.
Selecting the right materials for a CCUS project requires considering low-temperature embrittlement . Materials with higher toughness at low temperatures , like austenitic stainless steels , may be optimal , particularly at depleted gas storage sites where severe Joule-Thomson cooling is a concern .
To ensure proper material selection , stainless steel suppliers will need to work closely with CCUS project teams and consider the unique environmental factors and potential upset conditions involved in CCUS operations .
Conclusion
The use of stainless steel in CCUS projects is crucial to ensure long-term integrity and meet the safety requirements for operation . In CCUS systems , stainless steel is primarily used for equipment such as compressors and tubing for injection wells . To effectively capitalize on this emerging market , manufacturers must understand the operating conditions that the wellhead , equipment , and piping components will be exposed to , including the risks posed by impure CO 2 at all possible operating conditions .
