A method and cyclonic separator are disclosed for degassing a fluid mixture comprising a carrier liquid and one or more gaseous and/or vaporizable components, wherein: &#x2014;the fluid mixture is accelerated in a throat section () of a vortex tube () such that the static pressure of the fluid mixture is decreased and vaporizable components evaporate into a gaseous phase; &#x2014;the accelerated fluid mixture is induced to swirl within the vortex tube such that the fluid mixture is separated by centrifugal forces into a degassed liquid fraction and a gas enriched fraction; &#x2014;the degassed liquid fraction is induced to flow into a liquid outlet conduit () which is located at or near the outer circumference of the vortex tube (); and&#x2014;the gas enriched fraction is induced to flow into a gas outlet conduit () which is located at or near a central axis of the vortex tube ().

Cyclonic separator and method for degassing a fluid mixture

An over-pressure protection system having a conduit section extending between a pressure reduction valve and a low-pressure fluid handling system, a shut-off valve provided with an actuator arranged in the conduit section, pressure sensors arranged one on either side of the shut-off valve in the conduit section, a safety control system that communicates with the actuator and the pressure sensors which produces a signal when it detects a high pressure in the conduit section, and a self-diagnostic system for checking the shut-off valve and the pressure sensors that communicates with the actuator, the pressure sensors and the safety control system, which self-diagnostic system produces a signal when it detects a failure in either the shut-off valve or the pressure sensors or both.
