Online salinity measurement in oil/gas pipeline

Online salinity measurement in oil/gas pipeline

Online salinity measurement in oil/gas pipeline

(OP)
I have been searching for a sensor that would be permanently installed online on a pipeline to measurement the salinity level of an oil/gas well. Does anyone know of such a device?

RE: Online salinity measurement in oil/gas pipeline

This water cut meter from ROXAR (former Fluenta i think) will also give you the salinity:

Its the 2. model mentined in the brochure (p3-4)

RE: Online salinity measurement in oil/gas pipeline

maybe you will need to have this confirmed - maybe it just corrects for salinity - but it says "auto" so somehow it must determine the salinity???

Best regards

Morten,

Thank you for your hint but Roxar Water cut meter is not appropriate for the job. The salinity detection system is just an indicator and not a quantitatif measurement.
The "Autozero" program is design to correct for a change in oil density and not salinity.
This salinity measurement (if I manage to find an online system) would be fed into a Multiphase meter to correct flowrates.

RE: Online salinity measurement in oil/gas pipeline

Unfortunately I can give only a negative advice. I tried to use a refractometer to define either MEG or salt content in a slug, but the optical surfaces were scaled in hours. We had tro remove the instrument and find other ways (actually by measuring flows, but it was a different application).

RE: Online salinity measurement in oil/gas pipeline

bewdley,
did you try an autu-wash option with your refractometer?
