Dears,

 

I have a question related to fluid flow which has solids content.

 

I have a multiphase gas/oil/water from well, for which pipe size needs to be calculated.

 

As per the reservoir data, the gas/oil/water mixture contains 4 mg/liter (80 micron size) sand and 16 mg/liter (20 micron size) sand.

 

What shall be the recommended velocity criteria, as AP RP 14E, does not mention the C factor for erosion case.

NORSOK P-001 specifies liquids with sand as 7 m/s but does not mention any footnote regarding the size of the sand particles and also velocity limitations for multiphase flow.

 

Is there a different set of equations/standards to be used while sizing considering the size of sand particles.

What shall be the C factor if erosion needs to be evaluated.

 

Thanks

Thanks Mr Ankur,

 

The link provided mentions about erosion velocity with no solids content.

 

Is there any formula or standards which specifies the max.alowable velcoity for multiphase flow containing solids.

Pratik,

 

Solids need to be quantified, which is provided as nominally solids free (solids less than 1 pound of solid per thousand barrels of liquid) in my post given as a link. Erosion velocity also sets the upper velocity limit for multi-phase flow. Exceeding the erosion velocity may lead to erosion and in a worst case scenario adverse impact on the mechanical integrity of the pipe leading to failure of pibe and subsequent production stoppage and environmental release of hydrocarbon mixtures.

 

Regards,

Ankur.
