Twister SwirlValve™
Improving Joule Thomson operations and separation performance
Page last modified
September 20 2023
The Twister SwirlValve is a minimum shear valve that promotes droplet coalescence in two phase flow by means of a generated swirl flow. It is a cost effective alternative to a conventional control valve and is used to improve the performance of downstream separators by increasing the handling capacity, or improving the quality, of the outlet streams. It enables a rise of natural gas production and reduces bottlenecks found in existing overloaded two or three phase separators.
Pro/con
Increased production capacity
Increased NGL production (C6+)
Lower export gas dew points
Easy to retro-fit in existing piping arrangements
Debottlenecks existing overloaded separators
Less liquid carry-over/gas carry under
Reduced maximum valve capacity due to Swirl Trim (for the axial flow valves)
Specification
