Dear All,

I have started sizing a new 3-p separator to separator gas/condensate/water.
The preliminary sizing of the separator using simple geometry rules has given me a vessel of 1.6 m (ID) x 4.8 m (T/T). When I started the firm sizing of the separator, I had the following results:
Dimensions: 1.8m x 5m (T/T)
L/D assumed :3
L/D calculated: 2.8

The thing is: Whenever I increase the surge and holdup times of the vessel, the vessel dimensions decreases. Although, it makes since using the question, I can't get it.

The excel sheet is attached.
I have used the sizing procedure called "Successfully specify Three-phase separators" by Wayne Monnery and William Svrcek (Univ of Calgary).

Could you please help me to find out whether this procedure is right or wrong?

Thank you,
Sherif

Dear all,

I am looking for some information about 3 phase separators, a lot of experts refer on chesources to the article that it was attached on this topic:"successfully specify three-phase separators" 1994
My problem is specifically refered to minimum droplet diameter, I am looking the tipical droplet diameter for an amine/hydrocarbon/gas separation, and for an sour water/hydrocarbon/gas separation.

The article, table 1, shows some recommended values, but it indicates the following:

* SG at 60°F < 0.85 min droplet diam= 127 micrometers
* SG at 60°F < 0.85 min droplet diam= 89 micrometers

One of them should correspond to < 0.85 SG and the other to >0.85 SG, but I do not know which one is the correct.

Additionally if some of you have another literature related to this matter (minimum droplet diameter) please let me know.

Thank you in advance
