Abstract
A power generation system with low CO2 emission utilizing methane hydrate (MH) is proposed in this study. Carbon dioxide capture and storage (CCS) technique is employed to reduce the CO2 emission. The performance of this system was evaluated by using a static process simulator. The power generation system is based on the Brayton cycle and is comprised of a compressor, gas turbine, and combustor, all of which can fit in the limited space available on the vessel which is anchored over the MH reservoir. In CCS, the emitted CO2 was absorbed by amine which is typical chemical absorbent of CO2. The performance of the amine was evaluated in this study. The calculation result shows that the thermal efficiency of the system is decreased with the increment of the pressure because of the mechanical work of the compressor. The thermal efficiency of the system using the amine absorption system was increased about 15% than that of the system with the direct dissolving system. When the flow rate of CH4 was 5,000 kg/h, the output power of the system was 30,000 kW that was the feasible value for energy supplying system.
