AI Technical Summary
Technical Problem
Existing Carbon Capture and Storage (CCS) technologies require significant power input for refrigeration to maintain storage pressure in intermediate liquid CO2 storage tanks, which is inefficient and costly.
Method used
Utilizing vaporized CO2 as a heat sink to assist in refrigerating the fluid stream withdrawn from the storage tank, thereby reducing the power requirements for refrigeration. This system includes a CO2 vapor return to the ship, which aids in maintaining ship pressure during cargo transfer.
Benefits of technology
The proposed solution reduces the power requirements for refrigeration by approximately 50% compared to using ambient heat sinks alone, while also ensuring independent CO2 vapor return to the ship, minimizing the risk of cross-contamination.
