| Abstract | In response to climate change, the Kyoto Protocol, and the need to reduce greenhouse gas emissions, researchers are looking to marine geological storage of CO2 as one of the most promising options. Marine geological storage of CO2 involves the capture of CO2 from major point sources (such as a power plant) and the transport of CO2 to storage sites in marine geological structures such as a deep sea saline aquifer. Since 2005, we have developed relevant technologies for marine geological storage of CO2. Those technologies include possible storage site surveys and basic designs for CO2 transport and storage processes. To design a reliable CO2 marine geological storage system, we devised a hypothetical scenario and used a numerical simulation tool to study its detailed processes. The process of transport CO2 from the capture sites to the storage sites can be simulated with a thermodynamic equation of state. We compared and analyzed the relevant equation of state, including the Benedict-Webb-Rubin-Starling (BWRS), Peng-Robinson (PR), Peng-Robinson-Boston-Mathias (PRBM) and Soave-Redlich-Kwong (SRK) equations of state. To evaluate the predictive accuracy of the equation of state, we compare the results of numerical calculations with experimental reference data. In a supercritical state (above 31.1°C and 73.9bar), which corresponds to the thermodynamic conditions of CO2 reservoir sites, the BWRS, PR, and PRBM equations of state showed a good predictive capability. On the other hand, the SRK equation of state showed a high error rate of 300% in the supercritical state. This paper analyzes the major design parameters that are useful for constructing onshore and offshore CO2 transport systems. On the basis of a parametric study of the hypothetical scenario, we suggest relevant variation ranges for the design parameters, particularly the flow rate, diameter, temperature, and pressure. Using the hypothetical scenario, we also studied how the thermodynamic conditions of CO2 affect on the fluid flow behavior and thermal characteristics of a pipeline transport system. In summary, this paper presents our analysis and deductions of the major design parameters that are useful for constructing onshore and offshore CO2 transport systems. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
