Abstract

Carbon Capture and Storage (CCS) is a key technology for reducing anthropogenic greenhouse gas emissions, in which pipelines play a vital role in transporting CO2 captured from industrial emitters to geological storage sites. To aid the efficient and safe operation of the CO2 transport infrastructure, robust, accurate, and reliable solutions for monitoring pipelines transporting industrial CO2 streams are urgently needed. This literature review study summarizes the monitoring objectives and identifies the problems and relevant mathematical algorithms developed for optimization of monitoring systems for pipeline transportation of water, oil, and natural gas, which can be relevant to the future CO2 pipelines and pipeline networks for CCS. The impacts of the physical properties of CO2 and complex designs and operation scenarios of CO2 transport on the pipeline monitoring systems design are discussed. It is shown that the most relevant to liquid- and dense-phase CO2 transport are the sensor placement optimization methods developed in the context of detecting leaks and flow anomalies for water distribution systems and pipelines transporting oil and petroleum liquids. The monitoring solutions relevant to flow assurance and monitoring impurities in CO2 pipelines are also identified. Optimizing the CO2 pipeline monitoring systems against several objectives, including the accuracy of measurements, the number and type of sensors, and the safety and environmental risks, is discussed.
