    Simplified flow scheme of the wet FGD process adapted for oxy combustion. Due to the higher water (up to 30 %vol, wet) and SO2 content in flue gas, the operating temperature of FGD is expected to be higher than 45°C, the typical operating temperature encountered in classic wet FGD. Depending on warm/cold recycle.

  • Hydrocyclone Wikipedia

    A hydrocyclone is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.
