What is the maximum particle diameter of the gas at the entrance of a vane pack without blockage occurs?

I read that is about 150 microns in GPSA, I'm not sure.

 

thanks a lot

Thanks for your answer. I understand that the value of K determines the area I need in vane pack. The deputy does not speak the maximum diameter of the particles that can be in the gas stream.

Quote of the GPSA where recommend a diameter of less than 150 micron particle.

 

"• Select a separable droplet size and size for the vessel

diameter using Eq 7-1. A droplet size of 150 microns has-been

Typically specified. This May be overly conservative for

vane pack and cyclonic mist extractors, Which Generally

Have gas and liquid Capacities higher than mesh pads. "

 

Also attached to a guide for the design of separators which recommends trabjar with no particles larger than 150 microns.

 

"For horizontal separators mist extractor, it is considered that

section secondary gravitational separation or settlement

particles equal to and greater than 150 microns in diameter are removed from

so that the exhaust function optimally without excessive burdens

liquid. Therefore, the terminal velocity is calculated as for

separators without extractor; but it is considered a particle diameter

150 microns for sizing. "

 

 

I hope you have understood my question

 

 

Thanks !

Hello, I am Ritixa. Studying Process Engineering and Design...

 

Recently i am searching for Mist eliminator design and i came across about pressure drop calculation.

 

Please help me out for better understanding..How to do vane pack design & how to calculate pressure drop across vane pack??????
