Chapter 15 - CO2 Conditioning and Transportation

Abstract

This chapter introduces a CO2 Conditioning and Pipeline Transportation project whose aim is to advance the development of cost effective and safe methods for CO2 compression and pipeline transportation. Optimized design for the compression process and pipeline system requires accurate and reliable predictions of fluid properties, particularly density and water solubility. Existing CO2 pipeline transportation systems are reviewed in terms of operational parameters, particularly drying specifications. Based on calculations of water solubility for a selected case, it is found that the most stringent drying requirements may be relaxed to ∼ 600 ppm. Today, there is little experience with subsea pipelines for CO2 transportation, particularly in deep waters and over long distances. The chapter also verifies the experimental data of thermodynamic models and tools for calculating properties for CO2 and CO2-rich mixtures.
