This book includes the fundamental of Chemical Technology, and explains with an example of a case study with respect to the calculations based on the fundamentals of Chemical Engineering. It initiates from the market analysis to the properties and then the selects the process with a valid reason. It then brings forward the process flow diagram and piping and instrumentation diagram of the process and with a help of heat and mass balance, fixes the size of the industry and then finally predicts the control strategy and gives the scenario of cost estimation. Thus, it helps to understand the basis of process and plant design.
