Improved entrainment separator for high velocity gases and reheating of scrubber gases

Sulfur oxides (SOx) are washed with high performance limestone scrubbing fluid from the flue gases by means of an improved circulation separator (130). The preferred embodiment of a one-way, countercurrent, limestone scrubber (100) (which has a contact surface having a height of less than 6 m) has a gas velocity greater than 4.5 m / s, removes a substantial part of the scrubbing liquid from the vertical gas stream and the gas stream is well dewatered , horizontal directional dehumidifier (140). The forced circulation separator (130) is a single-flow device whose plates deflect liquid droplets from the upper part of the scrubber (e.g., top) of the scrubber and allow periodic washing. A vertically oriented, horizontal axis, rotating heat exchanger (431) greatly reduces the space requirement and the amount of wires required. ŕ
