Optimization of vortex tube parameters for heating throttled high pressure natural gas at wellhead
The heating performance of the vortex tube enables it to replace the heating furnace to heat the throttled high pressure natural gas at the wellhead.To choose the optimal structural parameters and operating parameters of the vortex tube,and give full play to the heating effect of the vortex tube on high pressure natural gas at the wellhead,this paper uses Fluent to carry out numerical simulation research to constructa vortex tube model for heating high pressure air gas at the wellhead and verifies the mathematical model and simulation results through the comparison with the experimental results.When the length of the vortex tube is 188 mm,the diameter of the cold end tube is 7 mm,the number of inlets is 6,the taper is 6°,the intake flow is 0.18 kg/s,and the cold flow rate is 0.6,the best heating effect is achieved.Based on the wellhead temperature and pressure parameters of the gas well,the series-parallel combination mode of the vortex tube is determined,and the economic comparison between the two heating ways using the vortex tube and heating furnace respectively is carried out.The results show that the vortex tube manifests a good heating effect and has significant economic benefits.
