Multiport Selector Valve (MSV)

Dear engineers,

We are in the FEED stage of designing a facility to produce 50 KBOPD. We have 6 well pads to achieve this production. Each well pad is with an oil gathering manifold. The consultant recommends the manifolds be provided with a multiport selector valves, comprising a housing with many production inlets, allowing for the diversion and testing of fluid from any individual line through a rotating plug, while the remaining lines continue to flow to a common group outlet instead using a conventional manifolds, which includes separate production and test headers. The justification of Consultant for using multiport selector valve is that they require less space, reduce manual operation and human error

In all our facilities, we use a conventional manifold instead of a multiselector manifold since our current and future facilities are onshore ones so there is no issue with space

Is there anyone here with experience in multiport selector valves? and Which manifold is preferred and has better availability? is it coventional or multiselector one If you could provide me with documents explaining these valves, because I have been looking for documents about them and I have not been finding any information, only simple product bulletins.


Thank you in advance.

I get it now. So the valve main body essentially is your manifold and the the centre turntable runs to the smaller central pipe off to the test separator or whatever.

They use less valves for sure as well.

The Fisher site gives more information. https://www.emerson.com/documents/a...-multiport-flow-selector-valve-en-4261162.pdf

They are not commonplace I suspect and my issue would be with the seals and how long they last as you move from port to port plus it means you need to run through a test separator all the time or have one inlet spare to "park" the divertor line so all flow goes to the main outlet.

they look pretty neat, but would be interesting to see the price comparison. I would put these in the same space as pigging valves - works for some lines and companies, but do they make a significant difference?. I suspect not.
 
Stay away from these multiport selector valves ( 3 way , 4 way, 5 way etc) , particularly in this service where sand in the production fluids can tear up the soft teflon internals. There is no telling where the fluid will go to when these valves leak internally.

Thank you so much Littlench. One of the justifications for using is that they are with less cost comparing to conventional manifold as consultant claims, i agree with all what you said. I hope other members involve in this thread to add more information.. some engineers do not recommend them especially from operational point of view..

Thank you george, you have raised an important point about the service with sand
 
@shvet , if you can share with us your point of view. l am waiting other members to join this thread.
