Using several software packages, this text helps students quickly and effectively understand chemical engineering unit operations and solve chemical engineering problems. It focuses on the computer applications of the main unit operation processes in chemical engineering, explains the theory of these units, and shows how to perform hand calculations and verify results obtained from simulation packages such as HYSYS. The book provides numerous real-world examples of chemical engineering processes, including flow in pipes, pumps, compressors, heaters, coolers, reactions, absorption, and distillation extraction.
