<p>PURPOSE:To enhance energy efficiency by injecting high-pressure seawater into a CO2 dissolving tank and decompressing it to 3kg/cm<2>G and after seawater dissolved with CO2 in this state introducing compressed air thereinto and thereafter discharging the seawater with a circulating pump and replacing seawater. CONSTITUTION:CO2 is pressurized with a CO2 compressor 1 and stored in a CO2 reservoir 2 and on the other hand, seawater is injected into a CO2 dissolving tank 5 from the outboard with a seawater circulating pump 7 and the residual air in the tank 5 is discharged by opening a discharge valve 12 for residual air and the tank 5 is decompressed to 3kg/cm<2>G with a dwell pressure valve 8. CO2 is passed via a drain filter 3 and discharged from a diffuser 6 and completely dissolved. Thereafter the pressure in the CO2 dissolving tank 5 is pressurized at the outboard depth pressure via a pressure regulation valve 9 with a compressed air source 13 and the seawater in the tank 5 is replaced with the outboard seawater by the seawater circulating pump 7.</p> |
