Résumé

In this work we present a dynamic model of a full-scale low-pressure liquid CO2 ship terminal operating at 7.0 bar(a). The envisioned CO2 terminal is of a scale relevant for carbon capture and storage, with a land terminal capacity of 30,000 m3 distributed on 6 tanks, and a ship cargo capacity of 25,000 m3 distributed on 5 tanks. Liquid CO2 loading is simulated from the onshore tanks to the ship tanks, including vapour return and purge. The simulations, including ramp-up to nominal transfer rate, steady-state transfer and subsequent ramp-down, are initiated with different initial values for ship tank temperatures to investigate peak vapour return rates and the vapour amounts that must be handled during the cool-down and transfer period. High initial tank temperatures will temporarily cause additional evaporation of liquid CO2, which in turn must be returned ashore and/or vented to the atmosphere to avoid pressure build-up, influencing terminal design and operation.
