AMPP 21532 Guide – Monitoring the CO₂ stream

In this technical article, we’re looking at the final two steps of the AMPP 21532 Guide – monitoring and memorandum of change. Once all the design steps are completed, and the project goes forward for construction and operation, the AMPP guide recommends that a robust monitoring system be implemented.

Monitoring Critical Impurities:

Monitoring the CO₂ stream presents several challenges that demand careful consideration. Academic research has identified various concerns that must be addressed to ensure uninterrupted operation and the ability to monitor critical impurities. Key factors to be addressed include determining optimal sampling points along the fluid processing steps and across the pipeline’s orientation. This is crucial due to impurities of different densities settling into distinct portions of the bulk stream. Sampling at high pressure and in the presence of multi-phase flow introduces further difficulties in obtaining representative samples.

Moreover, deciding which impurities to monitor is essential, as each impurity may require its own dedicated analyser, frequently calibrated to the bulk fluid. Professional advice may be necessary to identify critical impurities that warrant strict monitoring. Comprehensive impact assessments and failure analyses are also vital in predicting potential system failures. Reliability modelling, with the assistance of OSTI data as a reliable starting point, can aid in the assessment process. Recognising the ripple effects of failures is crucial, as the entire operating strategy can be disrupted. Dilution requirements to mitigate corrosion risks, for example, may be compromised if a single emitter experiences shutdown. Having a robust plan in place minimises the impact of such events.

Adapting Through a Full System Lens:

Once a monitoring strategy is established, the need to react to upsets and major changes in operating conditions becomes paramount. During project startup, the monitoring strategy assumes critical importance in managing project integrity. Should unexpected upsets or significant alterations occur, a memorandum of change becomes necessary to ensure safe future operations. These changes may extend to various aspects of the project, including the CO₂ specification. Engaging the right experts is essential to facilitate a smooth restart of operations and minimise disruptions within the CCUS project.

Implementing a comprehensive monitoring system and establishing adaptability through a full system lens are vital for ensuring operational excellence in CCUS projects. By effectively addressing the challenges of monitoring critical impurities and promptly adapting to changes, project stakeholders can confidently assure the reliability and safety of their operations. Engaging experienced consultants with a deep understanding of these aspects will undoubtedly strengthen project tenders and establish an edge in the highly competitive petroleum engineering industry.
