 It is currently being used for optimising existing Joule–Thomson (JT-LTS) systems to minimise liquid carryover.The swirl valve is exactly the same as a Joule-Thomson (JT) choke valve, but it enhances the performance of downstream separators for the same pressure drop, by maximising droplet coalescence.The technology can be applied where a low temperature separator is undersized, or when a lower pressure drop over a JT valve is needed with a similar dew pointing performance.
