12 - Gas purification, compression and liquefaction processes and technology for carbon dioxide (CO2) transport

Abstract

This chapter describes the gas purification and conditioning of large-scale CO2 for CCs for both pipeline and ship transport. A review of the existing literature is conducted and the optimal transport conditions and specifications are discussed. Then, six transport processes are described from a set of basic building blocks, followed by a sensitivity analysis of feed gas pressure, ambient temperature and feed gas composition. It is shown that the interface between the capture and the transport processes can be used to design more energy- and cost-efficient systems and that the transport processes must be designed on a case to case basis.
