Moving from raw material to finished product, this book demonstrates how to solve the main process-related problems that crop up in chemical engineering practice. It demonstrates the steps required to determine how much of various materials and chemicals are needed to satisfy output requirements and how to compensate for energy gained or lost for each step of the process. Presenting easy-to-understand methods, illustrations, worked examples, and practice problems, that are ideal for students, it provides access to a wealth of current calculations needed by chemical process professionals in petroleum/petrochemicals and biotechnology.
