A chemical process is a method used to change the composition of one or more chemicals or materials. In a chemical process, one or several chemical unit operations may be involved. These may include oxidation, reduction, hydrolysis, dehydration, alkylation, esterification, polymerization, nitrification, catalysis, etc. Process design, chemical synthesis and chemical analysis are central to chemical engineering and chemical processes. While chemical synthesis involves the selection of compounds and reactions to synthesize a product, process design determines the sequencing of units for the desired transformation of a material. Chemical analysis is concerned with the identification, separation and quantification of matter. The objective of this book is to give a general view of the different aspects of chemical processes and their significance. It includes some of the vital pieces of work being conducted across the world, on various topics related to process design, chemical synthesis and chemical analysis. The topics covered in this book offer the readers new insights in the field of chemical engineering.
