ABSTRACT

This chapter focuses on the development of mathematical equations to solve the mole balances and energy balances for different types of reactors, for instance, batch, continuous, membrane, and semi-batch reactors. This chapter firstly deals with solving the mole balance for each type of reactor system, with different examples. Secondly, the pressure drop due to a solid material is taken into consideration in the conversion and final composition; thus, adding the complexity of pressure variation. Thirdly, variation in volume is considered, which is the case for gas phase systems that can have variations in the number of moles, pressure, and temperature. Finally, the energy balance is added to the reaction system to solve the most complex scenario within this book. This chapter provides solutions for reaction systems that are isothermal, adiabatic, with constant external temperature, and with external cooling/heating fluids. Furthermore, the effects of these conditions on the conversion, yield, and productivity have been compared and discussed. The reaction rate is assumed to be known for the problems solved in this chapter, unless otherwise mentioned, and this assumption will be removed in the following chapter.
