FEASIBILITY STUDY OF HIGH DENSITY CO2 INJECTION FOR GEOLOGICAL SEQUESTRATION

Abstract

To reduce carbon dioxide, geological injection is carried out around the world. The injection and storage technologies have been developed in the global society. However most of the previous studies handled supercritical carbon dioxide transport and injection. The objective of the present study is to analyze the feasibility of high density liquid-like carbon dioxide injection. Generally, the density of liquid state is higher than that of supercritical state. That makes it easy to handle a huge amount of carbon dioxide. On the other hand, injection of liquid carbon dioxide should overcome some complex challenges such as ice and hydrate formations. In this study, fluid flow and heat transfer of liquid carbon dioxide in topside, riser, subsea flowline and wellbore was numerically analyzed.ansport and injection.
