TRACER STUDIES IN A PLUG FLOW REACTOR

TRACER STUDIES IN A PLUG FLOW REACTOR

A plug flow reactor (PFR) is a type of chemical reactor where the influent is pumped into the pipe. Chemical reactions occur through the length of the PFR and the reaction rate is not a constant. In this study, tracer experiments were carried out in a PFR built in-house.

A loop reactor is a hybrid type of catalytic reactor that physically resembles a tubular reactor, but operates like a CSTR. The reaction mixture is circulated in a loop of tube, surrounded by a jacket for cooling or heating, and there is a continuous flow of starting material in and product out. PFR (plug flow reactor)

Tubular reactors resemble batch reactors in providing initially high driving forces, which diminish as the reactions progress down the tubes. Flow in tubular reactors can be laminar, as with viscous fluids in small-diameter tubes, and greatly deviate from ideal plug-flow behavior, or turbulent, as with gases.
