Reducing Energy Consumption and CO2 Emissions in Natural Gas Preheating Stations Using Vortex Tubes

This work proposes an innovative method for adjusting the natural gas from grid to consumer pipeline requirements in a full-scale pressure reduction station. The use of two counterflow vortex tubes instead traditional boiler preheat before throttling is demonstrated as powerful alternative. Thus, fossil fuel consumption reached, which amounts 7.1% less CO2 emitted. To ensure optimal configuration, tube was thoroughly characterized laboratory facilities using nitrogen working fluid. Various operating conditions were tested determine most efficient setup. Computational Fluid Dynamics (CFD) simulations conducted with validate behavior tube. Subsequently, fluid switched methane assess performance differences between gases. Finally, deployed at installation and under real demand. results obtained this study offer promising insights into practical implementation proposed flow, highlighting its potential reducing minimizing emissions. Further improvements refinements can be made based on these findings.
