1 Scope
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 CO 2 streams in a CCS project , from CO 2 capture via transport by pipeline and injection well through to geological storage.
It does not specifically address upstream issues associated with CO 2 sources and capture, although flow assurance will inform CO 2 capture design and operation, for example, on constraints on the presence of impurities
in CO 2 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 CO 2 source, even if delivered by a pipeline (e.g. blue hydrogen generation), and flow
of gas streams within facilities generating and feeding these into a capture facility
can impact flow assurance in CCS projects and networks. These are out of the scope of this document as well.
This document also examines the impact of impurities on the phase behaviour and physical
properties of the CO 2 stream which in turn can ultima...
