The scrubber will connect to the HCl Tank (25 Q) So how can I design if I have data only HCl(g) inlet is 35% and after scrubber is should be 200 mg/m3. The liquid contacts the gas, and the contact area is enhanced by the use of packing, which disperses the liquid and the gas, providing more contact area to transfer the targeted component into the liquid. This effectively increases the size and mass of the particles, making them easier to collect in a subsequent filter or separation process. An English Chinese Japanese Dictionary of. Upon analyzing the aforementioned approach, it was found that the usual practice of fixing a “reasonable” wet pressure drop at the flooding point (e.g., 1025 Pa/m) may not yield the correct flooding velocity of the gas, particularly at higher liquid loads. Another disadvantage is that they generate waste in the form of a sludge which requires treatment and/or.
