This comprehensive guide covers the major elements of process control in a well-defined and ordered framework. Concepts are clearly presented, with minimal reliance on mathematical equations and strong emphasis on practical, real-life examples. Beginning with the very basics of process control, Automated Continuous Process Control builds upon each chapter to help the reader understand and efficiently practice industrial prChemical process controlAutomationProcess controlAutomationElectronic books.Chemical process controlAutomation.Process controlAutomation.660.2815660/.2815Smith Carlos A.1943-21287MiAaPQMiAaPQMiAaPQBOOK9910143225803321Automated continuous process control2069222UNINA
