Hydrodynamic Analysis of Spinning Cone Column by Computational Fluid Dynamics

Nowadays Spinning Cone Columns (SCC) are facing widespread application in chemical industries. In this work, the pressure drop parameter of the air and water system inside the SCC tower at pilot scale have been investigated by using computational fluid dynamics and compared with experimental data.The model studied in this work consisted of two stages of the tower and the dry and the two-phase pressure drop at rotational speeds of 500, 1000 and 1500 rpm were obtained and the effect of rotational speed on the amount of pressure drop inside the tower has also been investigated. The average relative error in the case of dry pressure drop was 11% and for the two-phase pressure drop with the liquid flow rates of 0.6, 0.9 and 1.5 kg / min was 13%. The simulation results also show that as the rotational speed increases, the system pressure drop also increases.
