A case study on suspended particles in a natural gas urban transmission and distribution network

Design and simulation of high pressure cyclones for a gas city gate station using semi-empirical models, genetic algorithm and computational fluid dynamics

“…Table 2 gives the desired conditions to design the cyclone. The measured particles concentration, diameter (d p ) and frequency of them (x i ) in winter were used from our previous study (Azadi et al, 2012.…”

“…The highest measured concentration of black powder was in winter, which equals to 22.09 mg/Nm 3 (Azadi et al, 2012). According to this concentration, the volume of particle collector for the designed cyclone was calculated.…”

“…(Azadi et al, 2012) measured the concentration and size distribution of black powder for summer and winter seasons in the natural gas entrance to the CGS #1 of Kerman city. In this study, the mentioned measured data were used to simulate the designed cyclone.…”

“…These particles are one of the important problems in gas transmission pipelines. To remove these particles from natural gas, a filter-separator or gas cyclone separator is used (Azadi et al, 2012).…”

“…It was found that the current filtration system cannot remove the solids properly. Having considered the size distribution of particles and evaluation of possible separation equipment of solid particles from natural gas flow, it was concluded that using cyclone separator before the filtration process in the City Gate Station (CGS) can highly increase the separation efficiency of solid particles (Azadi et al, 2012).…”
