Separation of a Two-phase Reaction Mixture in Tubular Devices

4 Separation of a Two-phase Reaction Mixture in Tubular Devices 

The components of two-phase reaction systems usually differ in density and viscosity, which is the reason for flow layering, especially at high flow rates. This is the lower limit of the output of a tubular turbulent reactor for fast chemical processes, including the interphase boundary. 

One must note that the uniform distribntion of the dispersed phase results in a longer length of the homogeneous flow zone in liqnid-liquid systems, than in liquid-gas systems. It is the consequence of less difference in phase densities. 

The separation of multiphase reaction system components in tubular turbulent diffuser-confusor devices occurs at high rates of flow. The peripheral area of a tubular turbulent diffuser-confusor device has a pressure gradient, which moves the particles in the opposite direction to the direction of the main flow (circulation zone). A liquid flow rotates in this area and an unusual effect appears centrifugal forces can lead to phase separation, which is mainly caused by the differences in the density of components participating in the dispersing process. Substantial differences in the densities of continuous and dispersed P2 phases and following the Pi condition 

Physical analysis proposes the analytical equation estimating the separation, where the numerical coefficient and the power index have been calculated by the processing of numerical calculation results
