Combined Flow Reactor Manufacturer,Supplier and Exporter in India
Product Code : EL-TWL-9159
Jlab Export is a leading Combined Flow Reactor Manufacturer,and suppliers in India
Two reactor types share one frame here: a coil tube plug flow reactor and a stirred mixed flow reactor, studied singly or as a combined system. Compressed air pushes the reactants through two rotameters, one for each. Saponification runs in each reactor and in the combination give the rate constant and show how the two types compare.

Experiments with Reactors in Series
Students run ethyl acetate and sodium hydroxide first through the plug flow reactor, then through the mixed flow reactor, and then through both together. At each steady state they take an outlet sample and quench it in excess acid. Back titration with Phenolphthalein as indicator gives the conversion, and a Digital Conductivity Meter gives a faster cross-check.
For the plug flow section with equal feeds, X/(1 - X) = k C_A0 τ_p. For the stirred tank, τ_m = C_A0 (X2 - X1) / (-r_A), with the rate taken at its outlet conversion X2 and X1 the conversion entering it. Students predict the outlet of the combined system from k found in the single runs and compare it with the measured value.
Frequently Asked Questions
What does MFR mean?
MFR stands for mixed flow reactor, another name for a continuous stirred tank reactor. Its contents are fully mixed, so the outlet matches the tank and the whole volume reacts at the outlet concentration.
Does the order of the two reactors matter?
For a first-order reaction it does not, and the final conversion is the same either way. For a second-order reaction such as saponification it does. Placing the plug flow section ahead of the stirred tank then gives the higher final conversion.
How is the space time worked out for each section?
Divide the volume of each reactor by the total flow through it. The stainless steel reactors hold about 0.7 litre and about 2 litres, so at the same flow the larger one gives nearly three times the space time.
Why is the plug flow section a coiled tube?
A coil packs a long tube into a small space, and the bends mix the liquid across the tube. Flow stays close to plug flow while the unit remains compact enough to share a frame with the stirred tank.
What air supply does it need?
It needs compressed air at 2 bar and 0.5 CFM. The pressure regulator and Bourdon gauge, both 0–2 kg/cm², hold a steady pressure on the feed, and the rotameters set each reactant flow.
