Hello, 

 

I am designing a three phase separator for a LPG stream with water. I have already design the Gas-Liquid separator part, and I am trying to desing now the boot with some of the information I found in this forum (article: succesfully design three phase separator), but I cant manage to develope it.

 

Please could somebody help me???

Thank you so much.

A 3-phase separator does not need a “boot” to operate effectively in segregating two liquid phases and a gas phase.  The greatest majority of 3-phase separators in the field do not function with a boot.  If you believe that you need a boot in your separator, please explain its scope or tell us what you expect it to do for the operation operate effectively.  If you can define what the boot is supposed to do, then we can work on helping you process design it.  Note that I state process design – not mechanical design.

eng123,

 

You need to consider a boot in your horizontal three phase separator if the ratio of the heavy phase (here water) volume flowrate to the total heavy and light; (here water+LPG) volume flowrate to be less than, say, 0.2, but on the other hand boot diameter has a mechanical limitation based on ASME Sec. VIII Div.1; UG-36 should be considered in relevant process design.
