New valve improves two-phase separation

Twister BV has unveiled the Twister SWIRL Valve -- a new gas-processing product that improves the separation of two-phase flow across a pressure reduction valve, such as a choke valve, Joule Thomson (JT) valve, or control valve. This in turn significantly improves the separation efficiency of downstream separators, the company says.

RIJSWIJK, Netherlands -- Twister BV has unveiled the Twister SWIRL Valve -- a new gas-processing product that improves the separation of two-phase flow across a pressure reduction valve, such as a choke valve, Joule Thomson (JT) valve, or control valve. This in turn significantly improves the separation efficiency of downstream separators, the company says.

SWIRL Valve technology will flow debottleneck existing separator trains, while minimizing liquid carry-over and/or gas carry under, reducing chemical losses, and enabling significantly higher liquid recovery, the company says.

The valve can be used to increase the flow capacity of existing JT-LTS plants, or to reduce the pressure drop required for JT cooling, or to lower the hydrocarbon dew point, and also to reduce glycol carry-over. SWIRL Valves can be applied for all Joule Thomson expansion gas flows.
