Fundamental of Chemical Processes is an essential problem-solving based book that explain the basic theories of material and energy balances. This book also provides systematic elaboration on the basic technique to the advanced calculation on the specific system. Stage by stage examples and solutions with clear explanation are provided to facilitate understanding on how to solve the problems on each chapter. The topics covered are unit measurement and conversion, process variables, material, and energy balances on non-reactive and reactive processes. The topics were deliberately discussed in easy-to-understand method that will promote enjoyable experience in learning the subject.
