Can anyone please share the step by step procedure on how to size the two phase and three phase separator (both horizontal and vertical). I would like to understand clearly. I have read GPSA hand book for the separator sizing , but it is confusing , i could not understand clearly. Please help.

GPSA is about as plain as it gets. You can look at the API recommended practice, too. You can use software on my website to confirm your understanding. If you register, you can download some stuff, too.

Hi do you mind have a similar document for liquid vessel sizing like reflux drum?
Thank you in advance!

Hi panagiotis,

Consider these links to support your work :

Bibles like Perry and GPSA should offer you more info.

 

Good luck

Thanks Breizh!

Some of the best information is found at the websites of demister vendors. Check a few. You can find many links at my website. The underlying physics & math is simple. It's the design criteria that is difficult to ascertain. The simplest criteria is found in API 12J. But I don't use this.

Hi,

You are welcome.

It took 2 years for someone to say Thanks.

It seems that it helped a lot of folks.

Can I get procedure for sizing horizontal 3-phase separator that has baffle & bootleg together?

[breizh]

Hi,

Consider this resource attached and the link.

Thank you Breizh for your reply

 

However the attached file does not have procedure for designing 3-phase separator with a bootleg & baffle simultaneously

[breizh]

Consider Google and/or the reference of the book in my previous reply.
We are trying our best to support.

to add to my answer, the bootleg is a capacity to help for the management of water draw. Residence time should 1- or 2-minutes max.
For the baffle you need data about the separation oil/water, decantation time.

Take a look at Bobby strain's website:

Horizontal Settler

 

Another reference is GPSA data book.

my 2 cents
