In packed bed scrubbers, the difference in particle and target velocities is very low due to the low gas velocity. Scrubber systems can be designed to remove entrained paniculate materials, scfm), and power input for a cyclonic scrubber is generally 1 to 3.5 horsepower per 1000 cubic feet per minute (hp/1000 cfm) [2, 6]. This is to be expected as there are so many variables to consider when going through various options, including venturi, packed-bed, or eductor venturi wet scrubbers. This work outlines a simplified design calculation procedure for the packed Tri-Mer packed bed scrubbers are versatile, reliable systems that serve the widest variety of processes. and specified worldwide.
