  • Patent number: 11384934
    Abstract: A process for discharging high-temperature flue gas safely from an ocean platform includes discharging the gas from combustion facilities into a main body of a cooling and cleaning device through an exhaust pipe, while sea water is injected into the main body. The injected water passes through a water distributor located at an upper part, and the scrubbing sea water is sprayed downwards. The high-temperature flue gas enters into a lower part, and the gas is scrubbed by the sprayed sea water to be low-temperature clean flue gas. The low-temperature clean flue gas passes through the water distributor and a mist eliminator, and is discharged into atmosphere through an outlet at a top of the main body. The sea water is collected to a liquid pool located at a lower part of the main body and discharged into the ocean. A cooling and cleaning device is also disclosed.
