Jlab Export is a leading Plug Flow Reactor Manufacturer,and suppliers in India
Conversion in this reactor builds up along a straight horizontal tube, because fluid that enters together leaves together with no back-mixing. The two reactants leave their feed tanks under air pressure, each through its own rotameter. The tube rises at its outlet end, where samples are taken to measure how far the reaction has gone.

Plug Flow Experiments for Students
Students set equal flows of two reactants, often ethyl acetate and sodium hydroxide, and wait until the outlet composition stops changing. Each outlet sample is titrated with a Burette or read on a Digital Conductivity Meter to give the conversion X. The space time τ for a run is the tube volume over the combined flow of the two feeds.
Each run gives its own k from the second order plug flow equation in the answers below. If the values agree from the slowest flow to the fastest, the assumed order holds. A steady drift with flow points to a wrong order or to back-mixing in the tube. Run with the same reaction, the Continuous Stirred Tank Reactor needs a longer space time for the same conversion.
Frequently Asked Questions
How does a plug flow reactor differ from a stirred tank?
Fluid in a plug flow reactor moves along the tube without back-mixing, and each cross-section has one uniform composition. Concentration falls steadily from inlet to outlet, so most of the tube works at higher concentration and the average rate is higher than in a stirred tank.
How do I find the rate constant from my results?
For a second order reaction with equal feeds, k = X / (τ C_A0 (1 - X)). For a first order reaction, k τ = -ln(1 - X). Use the inlet concentration after the two streams mix.
What does the upward bend at the outlet do?
The liquid has to climb before it leaves, so the horizontal tube cannot run part empty. Air that comes in with the feed rises to the outlet and is carried out. The volume used for the space time is then the volume that really reacted.
How close is a real tube to ideal plug flow?
Some mixing along the tube always occurs, from the velocity profile and from diffusion. A tracer test on the RTD Studies in Plug Flow Reactor measures this spread, which can then be allowed for in the design.
