Simulation Model for Dissolution of Liquid CO2 Droplets Discharged at Intermediate Depth of Oceal

초록

In the present investigation, calculations for solubility and dissolution behavior of liquid CO2 droplets released at 1000 m and 1500 m deep in the ocean from a moving ship and a fixed pipeline have been carried out in order to estimate the CO2 dissolution characteristics in the ocean. The results show the initial CO2 droplet diameter is of 0.011 m or smaller at 1,000 m depth and 0.016 m or smaller at 1,500 m depth from a moving ship. However, the initial droplet diameters for a complete dissolution should be 0.007 m or less at 1,000 m depth and 0.011 m or less at 1,500 m depth from a fixed pipeline, respectively. Therefore, the injection of liquid CO2 from a moving ship can be more effective means than from a fixed pipeline
