The carbon capture process model was established for an LNG ship, and the solution concentration and flow rate analysis selection under design conditions were carried out. The effect of solution flow rate on the carbon capture rate, energy and other key factors in the carbon capture system under off-design conditions was studied, and further research on the exhaust gas treatment mass flow and solution flow rate control was conducted under 75% MCR conditions. The results of the study showed that the energy of CO2 regeneration and CO2 removal rate increased significantly with the decrease of main engine load. The solution flow rate at the optimum operating point decreases approximately linearly with decreasing main engine load, while the optimal liquid-to-gas ratio (molar) does not tend to change with changing main engine load, so the solution flow rate can be controlled approximately linearly to achieve the optimum capture operating conditions when the main engine load changes. The appropriate exhaust gas treatment mass flow and solution flow rate can help to further reduce the regeneration energy based on the high CO2 removal rate. Up to 82.8% CO2 removal rate can be achieved at the regeneration energy of 9.477 GJ/T CO2 under 75% MCR condition. This study can provide a reference for the control of carbon capture effect under off-design conditions of ships.
