Following the approval in principle (AIP) of CCS and RINA, recently, the onboard hypergravity carbon capture system independently developed by COSCO SHIPPING Heavy Industry Technology (Weihai) (CHIT) has obtained the AIP of American Bureau of Shipping (ABS).
During the certification period, ABS organized experts to conduct a comprehensive review of the information on the hypergravity carbon capture system with reference to the “Requirements for Carbon Capture and Storage on Board Ships” issued by ABS. Professional specification guidance was provided on key indicator testing, absorbent use, solid waste treatment, and system applicability onboard, which finally confirmed that the onboard hypergravity carbon capture system developed by CHIT complies with the requirements of the ABS specification.
The system takes the hypergravity equipment as the core, through the strong centrifugal force generated by high-speed rotation, the liquid is torn into micro-droplets, so that the fluid is in full contact with carbon dioxide in the highly turbulent and high specific surface area conditions, so it greatly improves the efficiency of gas-liquid mass transfer, and the system carbon dioxide absorption rate is ≥93% in the conditions of the absorber and the exhaust gas volume of the liquid-gas ratio (L/m3) 0.67:1.
The hypergravity carbon capture system utilizes the high efficiency mass transfer advantage of the hypergravity equipment, which can significantly reduce the amount of system absorber circulating, and can make make the circulating pump power, the volume of the solution tank, and the ship’s steam consumption related to it decrease significantly, thus effectively reducing the energy consumption of the system and the size of the equipment.
The design and development of the carbon capture system provides ship owners with a carbon emission reduction program that combines the applicability of the ship model and short- and medium-term technological advantages, demonstrates CHIT’s technological innovation strength, and opens up a new market for carbon capture in the shipping industry.
