This invention relates to a marine exhaust gas treatment system, specifically a shipboard biphase absorbent carbon capture system based on a centrifugal phase-coalescing-heat exchanger integrated unit. This invention proposes a highly efficient and low-energy-consumption shipboard carbon capture system based on a centrifugal phase-coalescing-heat exchanger. This technology combines a centrifugal phase separator, a heat exchanger, and a coalescer. The lean and rich liquids flowing from the bottom of the absorber tower undergo heat exchange and centrifugal phase separation in the integrated centrifugal phase-coalescing-heat exchanger. This technology not only reduces the need for reheating, temperature rise, and centrifugal separation after the phase separator, effectively solving the problem of low phase separation efficiency caused by ship rolling, but also effectively reduces equipment size and floor space by combining the phase separator and centrifugal heat exchanger.
