Abstract
Carbon dioxide ocean disposal is one of the promising options to reduce carbon dioxide concentration in the atmosphere. So, in the present study, calculations of the solubility, the surface concentration and the dissolution behavior of carbon dioxide when liquid carbon dioxide is released at 1,000m and 1,500m in depth are performed. The results show that liquid carbon dioxide changes to carbon dioxide bubbles around 500m in depth, and the hydrate acts as a resistant layer for the dissolution of liquid carbon dioxide. Also. the injection of liquid carbon dioxide from a moving ship is more effective than that from a fixed pipeline.
