Review of Differential Calculus and Numerical Methods

In the study of chemical engineering systems, we find it necessary to consider the variation of a particular quantity as dependent on the variation of another. For example, in the study of chemical kinetics the concentration of a species undergoing a chemical reaction varies with time. Here, the concentration profile of the reactant species is considered to be a function of time. In general, if to each value… Read more

Review of Macroscopic Balances

In the study of chemical engineering systems, we find it necessary to write conservation laws for “macroscopic systems” that include large pieces of equipment or parts thereof, like chemical reactors, pumps, compressors, flash drums, distillation columns, pipes and other. The conservation laws allow us to monitor the behavior of these systems and take corrective action if necessary. They also allows us to size the equipment and to optimize the process behavior in order to minimize costs of production or maximize revenues. In this monograph we will present the generic form of these… Read more
