The reactor is heated by high pressure steam which has a temperature of 470 K and is fed into the reactor at point 1 and leaves the reactor at point 2. The reactants flow through the tubes. Tubular reactors are used, for example, in the steam cracking of ethane, propane and butane and naphtha to produce alkenes.

The residence time for a CSTR is the volume divided by the total flow of feeds. For a batch reactor, the residence time is the cycle time. In a CSTR some of the reactants appear in the discharge within one turn over time, which in general is less than 1/20 of the residence time. The amount of time spent in the

In a CSTR, one or more fluid reagents are introduced into a tank reactor (typically) equipped with an impeller while the reactor effluent is removed. The impeller stirs the reagents to ensure proper mixing.Simply dividing the volume of the tank by the average volumetric flow rate through the tank gives the residence time, or the average amount of time a discrete quantity of reagent spends .

In a PFR, one or more fluid reagents are pumped through a pipe or tube. The chemical reaction proceeds as the reagents travel through the PFR. In this type of reactor, the changing reaction rate creates a gradient with respect to distance traversed; at the inlet to the PFR the rate is very high, but as the concentrations of the reagents decrease and the concentration of the product(s .
