Sour gas flowmeters
Sour gas flowmeters
(OP)
Gents,
We are revamping a claus unit and have some problems with our exting orrifice flow meters. I was wondering if there are any smarter sollutions.
We've looked into :
- thermal flowmeters, not much references, need constant gas composition for correct measurement, the sensor can load up with impurity's.
- ultrasonic flowmeters, relatively expensive but can work when heated and traced properly.
Do you have any suggestions, experiences or tips ?
Thank you very much,
Regards

Its the sour gas feed into the claus unit that we want to measure.
We have two sour gas suppliers :
- one coming from a HDS unit that has been treated in an amine unit.
- one coming directly from our sour water stripper units.
=> both streams contain H2S gas going into the claus unit.

Today, I'd go with external ultrasonic meters. lowest risk to humans.

We are starting to built a new Claus complex in a refinery in Argentina, and the sour gas flow meters are venturis made of stainless steel, I think they would be Daniel, because the available pressure is very very low.
For the clauss off gas, the basic engineer contractor put an annubar, but we don't see too much future..
