Supersonic nozzle efficiently separates natural gas components

A new technology based on the adiabatic cooling of swirling gas flow in a supersonic nozzle is effective in separating and processing natural gas components.A pilot test facility in Alberta, Canada, has shown that the 3-S separation device uses 10-20% less compressor power than plants that use a Joule-Thomson valve or turboexpander, based on the same extraction level.Potential applications for 3-S separators in gas processing plants include:• Gas preparation for transportation.• LPG extraction, shallow cut, and deep cut.• Offshore gas separation and treatment facilities.• CO2 extraction, ethane recovery, and LNG applications.3-S separators provide a cost-effect...
