Impinging stream gas-liquid reactor

The gas-continuous impinging stream gas-liquid reactor for the experiments of wet desulfurization of flue gas employs the flow configuration of horizontal coaxial two impinging streams, as shown in Fig. 7.9. 

The impinging stream gas-liquid reactor has low hydraulic resistance. In the range of operation conditions tested, the pressure drop across the reactor, Ap, is round 400 Pa only.

It can be seen that in the combined multifunctional impinging stream gas-liquid reactor shown in Figs. 7.21 and 7.23. the working principles and action in enhancing transfer between phases for each sub chamber of absorption are the same as those of the reactor shown in Fig. 7.10. The first difference between the two reactors is that a pair of impinging streams is added in the direction perpendicular to the flow axis of the original pair of impinging streams. As a result, the utilization factor of the space inside the sub chamber is increased.
