Dear Friends,

I Am Working On One Project Where I Need To Fix Up The Parameter Outlet Composition At The Outlet Of Three Phase Separator.

Outlet Composition What I Need Is,
1) Oil In Water
2) Water In Oil
3)Liquid Carry Over With Gas

Please Give Me Some Idea Your Thoughts So That I Can Able To Solve These Issue.

Regards,

Ajay

ajay:

What you have done is ridiculous and very impolite.

You have forced me to delete your previous FOUR (4), identical posts on the same topic. You have not even had the courtesy of saying "I'm sorry" or "I made a mistake", "I was asleep at the keyboard", or "my dog made me do it", "I apologize for causing so much trouble" -- and all this while expecting to be helped out..

Kindly start reading the Forum guidelines and rules and stop creating multiple posts on the same topic.

Ajay,

You will definitely need more information in order to resolve this problem. There are no universal specs for vessel outlet streams - it all depends on downstream equipment requirements.

Dear Friends,

I Am Really Sorry For Posting The Same Topics 4 Times But It Was Not My Mistake Actually My Net Was Not Responding At That Time Anyways Really Sorry Please Forgive Me.

To Zauberberg,

Let Me Know About The Additional Information Which Is Required To Fix Up Those Parameters.
If Possible Please Brief Me What Are The Parameters Exactly Matters To Decide This Outlet Parameter Configuration & How Doese They Affect.

Thanks In Advance.

Ajay,

These specs should be defined based on Process Design Standard you're using at the moment. I cannot give you more detailed information without knowing where do you plan to route the separator gas stream, hydrocarbon liquid stream, and the waste water stream. If you know what kind/type of equipment is located downstream of your 3-phase separator, the answer should be more or less straightforward.

Zauberberg,

At The Downstream Of Separator We Are Having 1)Condensate Stabilization Module With Coalscer To Reduce Water In Oil. 2)Produced Water System To Reduce Oil PPM.3) Gas Stream Will Route To Compressor Via Scrubber.

I Have One More Doubt How Vendors Are Calculating These Parameter & Giving The Performance Gurantee Of Separator Performance.If You Know Please Guide Me So That I Can Also Find Out The Separator Performance In Next Project.

Ajay

1. Vapor phase: feeding the compressor. If there is a dedicated scrubber downstream of 3-phase separator, considering a common KO drum should be good enough for intial vapor-liquid separation. I never believe to design standards regarding allowable K-factors, and I would try to size both inlet separator and compressor suction scrubber based on the most conservative values.

2. Liquid-Liquid separator. This portion of design will depend on the overal gas-to-liquid ratio, i.e. whether the separator is vertical or horizontal. In case of lower GLR, consider conventional horizontal separator with a boot, where diameter is calculated based on mixed liquid phase axial velocity between 15-25 mm/sec, at normal liquid level in the drum.

There are many factors influencing the design of separator (fouling, system pressure, GLR, tolerance to carryover/carryunder, etc.) so make sure to take all these things into account.

Thanks Zauberberg.
