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 pr 606 $aChemical process control$xAutomation 606 $aProcess control$xAutomation 615 0$aChemical process control$xAutomation. 615 0$aProcess control$xAutomation. 676 $a660.2815 676 $a660/.2815 700 $aSmith$b Carlos A.$f1943-$021287 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911019745003321 996 $aAutomated continuous process control$94422192 997 $aUNINA
