Title: Calculation of reactor volume and residence time
Abstract: This chapter examines how to calculate the reactor volume and residence time of material balances, which can be used to design reactors when one reaction is taking place. It also compares the behaviour of the different reactors. For a given conversion, the volume of a plug flow reactor (PFR) will always be less than that of a continuous stirred tank reactor (CSTR) for a positive-order reaction. The PFR tends to operate at higher reactant concentrations than the CSTR, since, in the CSTR, instantaneous dilution with the product takes place. This means that for positive-order reactions, PFRs will exhibit higher overall rates of reaction and therefore will have lower volumes than CSTRs for a given conversion. The chapter then looks at the recycle reactor, in which fresh feed is mixed with a recycle stream and then fed to the PFR.
