An innovative model for cleaner energy separations in a two-phase vortex tube

To meet the demands of offshore natural gas dehydration and heat recovery, this study proposes a vortex tube based natural gas dehydration and heat recovery process that accounts for coupled energy and mass transfer. A mathematical model based on the Euler-Lagrange approach, incorporating condensation and slip effects was developed and validated against nozzle condensation experiments, accurately capturing droplet nucleation, growth, collision, separation, and re-evaporation. The effects of inlet heterogeneous droplet mass flow rate, droplet diameter, and cold mass fraction on mass and energy separation were systematically investigated. Results show that mass separation and hot tube heating performance peak at…
