Automated Stream Analysis for Process Control V1

Automated Stream Analysis for Process Control, Volume 1 provides information pertinent to stream analyzers and its elements, including the system, construction, control, and operation. This book examines the results of the analysis, which must be used properly by the computer in order to regulate the process controls so that the process stream will obtain its ultimate goal. Organized into 12 chapters, this volume starts with an overview of the uses of liquid flow-injection analytical devices in process control applications within the chemical production plant. This text then examines the initial two techniques, namely, ion chromatography and ion exclusion chromatography that are used to analyze over 90 varieties of ions down to part-per-billion in aqueous streams in laboratory applications in academic, government, and industrial laboratories. Other chapters consider monitoring of gas streams generated from process development units. Chemists, chemical engineers, analytical chemists, as well as laboratory and plant managers will find this book extremely useful.
