Mist eliminators built into the scrubber vessel or provided as a separate vessel are used to collect the entrained water droplets after the scrubber. Particle capture is accomplished in a contacting vessel, such as a venturi scrubber, a tray tower scrubber, or a spray tower scrubber. Calculation ln HETP = 0.8374366 HETP = 2.3104368ft = 0.7042211m For separations, less than 15 theoritical stages, a 20% design safety factor can be applied. 0000225811 00000 n wet scrubbers nederman mikropul. 0000007446 00000 n 0000228350 00000 n 0000117006 00000 n 0000004603 00000 n Particulate contaminants are removed through impaction by the high-velocity spray of scrubbing liquid.
