| 제목 | Determination of optimal operating condition for ship transport of liquefied CO2 |
| 초록 | Large amount of CO2 can be transported via pipelines or ships. This study is concerned with ship transport of Liquefied CO2 (LCO2) due to its flexibility compared to the regional constraints of pipelines and wide range of applications. Ship transport of LCO2 consists of liquefaction, loading, maritime transport, and offshore unloading processes. A key to the design of transport system is to determine optimal temperature and pressure conditions of LCO2 because this significantly affects the system performance including liquefaction process at the onshore terminal, boil-off gas production in the tank, hydrates formation in the (un)loading line, etc. However, there are few studies that suggest optimal T-P condition of LCO2 in the literature. The available guidelines, if any, are simply suggested without systematic analysis from the viewpoint of integrated system. This study addresses the issue by formulating it as a multi-objective optimization problem that minimizes overall ship transport cost and other criteria. The suggested framework constructs Pareto-optimal front by designing an optimizer that iteratively calls the process flowsheet simulator. |
