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.

Fundamentals of Chemical Reactor Theory1

A Plug Flow Reactor (PFR) consists in a long, straight pipe in which the reactive fluid transits at steady-state (no accumulation). The main assumptions of this model are that the fluid is completely mixed in any cross-section at any point, but it experiences no axial mixing, i.e. contiguous cross-sections cannot exchange mass with each other.

Cost estimating for chemical engineering plant design

When a reactor is either heated or cooled, cost it as the sum of the cost of a heat exchanger plus that of a vessel. For a plug flow reactor, you calculate the area from the tube diameter, length and numbers. For a fluidized bed reactor use the Q and Ts to calculate the area as for other heat exchangers.
