Design of spray towers and activated carbon absorption towers
Thread Content
Dear experts, when dealing with equipment like spray towers, once the designed air volume is known, how can one determine the dimensions of the tower, the volume of air circulating within it, as well as the appropriate choices for pumps and fans? Are there any relevant design guidelines or materials available? I would appreciate it if you could share them. I’m not an expert in this field, but I’d like to learn more about such equipment. Thank you
Generally, the gas velocity in a spray tower is set at 3–5 m/s; based on this value, the tower diameter can be calculated. As for the tower height, it needs to be calculated by applying knowledge from chemical engineering principles. The circulation rate is determined by the liquid-to-gas ratio; this ratio varies depending on the medium, and this value is empirical. For pumps, the key parameters are currently flow rate and head; the flow rate margin is generally 1.1, while the head margin is generally 1.2. For fans, it is the air volume and outlet pressure.
I recommend that you carefully study the sections on gas-liquid mass transfer, absorption, and adsorption in the chemical engineering handbook, and ensure you fully understand them. Gradually, one will become an excellent chemical engineer.
This is usually calculated by professionals in the field of manufacturing processes
For a spray tower, it mainly depends on what is being absorbed, as well as the droplet dispersion rate and the mass transfer coefficient. There is a direct relationship between flow rate and the liquid-to-gas ratio.
I recommend two books to you; after reading them, you’ll understand everything. The first is: Principles of Chemical Engineering, and the second is: Chemical Engineering Equipment.
:'(The company hires recent graduate students with a degree in chemical engineering; they don’t know how to work with equipment or lack experience, etc.)
It’s written in great detail; I’ve learned from it, thank you
