6. Isothermal Reactor Design: Moles and Molar Flow Rates

Don’t let your fears ...Get in the way of your dreams

Overview. In the last chapter we used conversion to design a number of isothermal reactors for single reactions. While in many situations writing the mole balances in terms of conversion is an extremely effective strategy, there are many instances where it is more convenient, and in some cases absolutely necessary, to write the mole balance in terms of moles (N_A, N_B) or molar flow rates (F_A, F_B), as shown in Table S-l in Chapter 1. In this chapter we show how to make small changes in our CRE algorithm to analyze these situations. Using our algorithm, we first write a mole balance on each and every species, and second, we ...
