"A Step by Step Approach to the Modeling of Chemical Engineering Processes" is a specialized book that deals with the modeling and simulation of chemical engineering processes. It is aimed at students of chemical engineering and provides a clear and understandable entry point to complex mathematical models. The book builds on the existing knowledge and intuition of learners and teaches how to create a model and solve it using Excel. The author, Liliane Maria Ferrareso Lona, has made it her mission to make this often overwhelming subject more accessible. Through the step-by-step approach, readers are encouraged to solve practical problems that may arise in chemical engineering practice. The book addresses the wide range of phenomena covered in a chemical engineering curriculum and offers a compact and focused perspective on modeling and simulation without delving deeply into the extensive theoretical foundations.
