Tubular flow reactors output

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. 

The fact that the results obtained earlier and described above were experimentally confirmed was of great importance. The literature does not contain e iq)erimental investigations of rheokinetic problems in which the distribution of flow velocities or residence times (conversion) at the output of the tubular reactor would be studied. Therefore, the results of the experimental investigation of hydrolytic polymerization of dodecalactam in a pilot tubular reactor and the comparison of these results with computation [58] deserve a more detailed presentation. 

A diffuser-confusor reactor demonstrates a substantial increase of pressure at the input and drop at the output (Figure 2.37) the pressure drop is high (Ap can be approximately up to 1 atm). The correlation between the pressure change in tubular turbulent diffuser-confusor devices and the reaction mixture flow rate can be found in the following equations R = 0.99) [45, 97] ...
