Hi Folks,

 

There is a vertical two phase separator that separates gas from emulsion in a wellsite. The emulsion flows to the storage tank system under liquid level control in the separator (local pneumatic control). The separator operating pressure is 500 psig and tank is amospheric (500 psig pressure drop across the liquid dump valve). Maximum emilsion flow is 50 m3/d.

 

The separator is existing and the retention time for the emulsion is only 1 minutes. The purpose of the separator is not oil/water separaton and separator diameter is big enough for gas/emulsion separation. I was wondering what is the lowest retention time that  we can have for such a system? I guess the only imitations in here are operability and control...but I don't know what parameters I need to judge wethere 1 min rentetion time is enough and whether I can get this separator work in the field??

 

 

Thanks,

 

Amin

Amin,

Let you try to get a copy of "Gas-liquid and Liquid liquid separators" By Maurice Stewart and Ken Arnold to support your query.

Another good support is GPSA engineering data book . chapter 7.

 

Consider also to use the search engine in this forum , you may find clues.

 

Good luck.

It sounds like you are looking to use old equipment for service as a producing well gas-liquid separator. It is best if you have information about separators handling the same well fluids. Guides are good, but there is always the exception. So, look first for performance with a similar fluid. If you expect emulsion, then the fluid may produce foam, too. In this case, guides are not necessarily good to apply. The next best course is to find an operator or consultant who is familiar with production in the same field. Good luck. Let us know how it works.
