14 Mole Balances Chap. 1 in which there are no spatial variations in the rate of reaction (i.e., perfect mixing), it takes rhe familiar form known as the design eqrrarion for a CSTR: F~~ Al The CSTR design equation gives the reactor volume I{ necessary to reduce the entering flow rate of species j, from Fj, to the exit flow rate F,, when species j is disappearing at a rate -rj. We note that the CSTR modeled such that the conditions in the exit stream (e.g. . concentration, temperature) are iden- tical to those in the tank. The molar flow rate 6 is just the product of the con- centralion of species j and the volumetric flow rate u : Fl = Cj+ v p& - moles volume time volume time Consequently. we could combine Equations (1-7) and ( 1-8) to write a bal- ance on species A as 1.4.2 Tubular Reactor In addition 10 the CSTR and batch reactors, another type of reactor commonly used in industry is the ruhlliar rmr.ror: It consists of a cylindrical pipe and is When normally operated
