A system including an additive management system configured to oversee hydrate formation in a hydrocarbon extraction system, the additive management system including a flow meter configured to measure a fluid flow rate, a first sensor configured to measure at least one of a fluid property and an environmental condition, and a chemical injection device configured to inject a hydrate inhibitor into a fluid flow.

Additive management system

A technique facilitates monitoring of a multiphase fluid flow. The fluid flow is directed through a choke valve comprising a choke actuation system which controls a flow rate of the fluid passing through the choke valve. The choke valve also comprises a velocity reduction area which is created by a choke gallery. The choke gallery reduces the velocity of the fluid flow to encourage separation of phases of the multiphase fluid. A sensor is positioned along the gallery at a desired region to monitor a property of at least one separated phase of the multiphase fluid. For example, the sensor may be positioned proximate a bottom of the choke gallery to monitor a property related to a water phase which separates and transitions to the bottom due to its greater density.

Fluid properties measurement using choke valve system

A system including a controller configured to receive feedback from at least one sensor configured to monitor a fluid flow of a hydrocarbon extraction system. The fluid flow includes water and an injected chemical. Additionally, the controller is configured to determine a ratio of the injected chemical to water in the fluid flow.
