Does a hydrochloric acid exhaust gas absorption tower require packing? Seeking advice from experts
Filler (plastic) needs to be added to increase the contact and absorption area.
Make good use of the Teflon material; it will last longer
Using a falling film absorber or a packed tower
The function of packing is to increase the gas-liquid contact area, thereby improving the absorption efficiency. Of course, if the absorption tower is large enough and tall enough, packing may not be necessary; spraying water alone can also achieve the desired absorption effect. However, using packing allows the size of the absorption tower to be significantly reduced, so it is recommended to use packing
Exhaust gas absorption towers are generally made of PP or fiberglass material, and they contain PP multi-faced hollow balls or PP Böhlke rings, which increase the contact area and thereby enhance the absorption efficiency
