- In this article, an intermediate CO2 storage system for long-distance ship transportation was modeled. The storage terminal links the continuous CO2 liquefaction process to discrete marine ship transportation and performs as a buffer between them. It is composed of four distinct processes: a CO2 input process, a storage tank and loading process, a recirculation process, and a BOG (boiled-off gas) reliquefaction process. The entire system should be operated as a liquid phase. Consequently, operation conditions, tank capacity, insulation specification, and streamflow rates play a major role in operating the storage terminal securely. The goal of this study is to design a base case of the storage terminal and propose its appropriate operation condition which makes the terminal operate with minimum operation energy. Results of the base case simulations are compared with improperly insulated systems on the pipeline and tanks that generate more BOG than the base case. The total operation energies of the base case and case studies are presented, and it turns out that approximately three times the operation energy is required if the system is not properly designed.
