Carbon dioxide capture, transportation and geological storage — Cross cutting issues — Flow assurance

This document describes and explains the physical and chemical phenomena, and the technical issues associated with flow assurance in the various components of a carbon dioxide capture and storage (CCS) system and provides information on how to achieve and manage flow assurance. The gaps in technical knowledge, limitations of the tools available and preventative and corrective measures that can be taken are also described.

This document addresses flow assurance of CO2 streams in a CCS project, from CO2 capture via transport by pipeline and injection well through to geological storage. It does not specifically address upstream issues associated with CO2 sources and capture, although flow assurance will inform CO2 capture design and operation, for example, on constraints on the presence of impurities in CO2 streams, as there are too many different capture technologies to be treated in detail in this document.

Vessel transport and buffer storage that are considered in integrated CCS projects under development, are not covered in this document. Flow of material in the supply chain of a CO2 source, even if delivered by a pipeline (e.g. blue hydrogen generation), and flow of gas streams
