Seeking advice on the design of a spray tower for absorbing methanol using water
Thread Content
While studying chemical engineering design, I encountered a practical problem related to the design of spray towers as covered in chemical engineering principles; no matter how I tried to calculate it, I couldn’t obtain an ideal result. I would like some help. Thank you to the teachers who assist me. Conditions: After being condensed in a condenser, the methanol-containing gas is absorbed again. The flow rate of the gas is 200 m3/h; the methanol content in it is low (it can be assumed to be 3%). The gas temperature is at room temperature, and the absorption efficiency is assumed to be 95%. Additional information ； If other parameters are missing, please calculate based on general circumstances. Thank you again!
There are many concepts that are lacking; for example, at first I got the liquid phase and the absorption liquid mixed up, and I thought that a flow rate of 0.4 m3/h for the absorption liquid in the absorption tower would be sufficient.
