한국의 수중 co2격리 프로그램

Abstract

In Korea an interdisciplinary project on underwater co2 sequestration has been started. One of the main potential sites for the sequestration is the “DolGoRae (Dolphin)” gas field located over the southwestern part of the East/Japan Sea. We plan to deliver CO_2 captured from the largest steel company in Korea (POSCO) to this site through pipe lines. To meet this end, chemical engineers study the behavior of CO_2 hydrates, mechanical engineers design the pipe lines and injection systems, geologists and geological engineers survey the geological structure of the potential sites, and oceanographers assess the environmental effects. From a preliminary study, we find that we can store captured CO_2 to the gas filed. In case, the CO_2 leaks from the storage site it would move to the north along the Korean coast on the average.
