Chemical engineering students and chemical engineers are being asked to solve problems that are complex, whether the applications are in refineries, chemical or pharmaceutical plants. The aim of this book is to demonstrate the problems in chemical engineering which have to solve by Finite Difference Methods. This book is a thorough presentation of Finite Difference Methods used in Chemical Engineering. The goal of this book is to help you practice better chemical engineering. It also contains case studies with worked out examples to demonstrate the Finite Difference Method. This book is for the Chemical Engineer lays down a foundation for numerical problem solving and sets up a basis for more in-depth theory and applications. This text addresses the needs of senior undergraduates in chemical engineering, and students in applied chemistry and biochemical process engineering/food process engineering also.
