Questions about waste gas treatment scrubbers
Thread Content
I’ve just started in this industry, and I’ve found that there are many details regarding the actual design of wash towers that aren’t clear. For example, calculating the tower diameter requires knowing the gas velocity in an empty tower, but those with more experience don’t need this information; they say it’s sufficient to use a standard value. Now I want to know how to determine the height of the packing and the overall height of the tower – all I know is the flow rate
Careful calculation is required; it is recommended to read a book on principles of chemical engineering
Generally, I calculate the volume by multiplying the residence time by the gas volume; once the volume is known, it’s possible to determine the diameter and height
Design still presents challenges; consider reading some books on scrubbers. There are several key design considerations: flooding velocity, plate spacing, etc. Design cannot be taken for granted.
For this, you need to adopt a more humble attitude and ask your seniors more questions until you understand everything. However, I am experienced in working with empty-tower spray systems; I’m not very familiar with packed towers
