| Contents of lectures | INTRODUCTION. ; The concept of automated analytical systems for measurement of input parameters, the installation of on-line meters in the line of technological processes, transport of the sample in a flow system, central control and the measurement of output parameters. Review of modern analytical methods and techniques of chemical measurements, control and monitoring of process in a chemical industry. Review apparatus, instruments, meters and sensor. Criteria for the methods selection. Assessment and applicability of the method for chemical analysis. The sensitivity and selectivity and the method detection limit. ; II. CHEMICAL METHODS FOR THE PROCESS CONTROL AND MONITORING. ; Overview of modern instrumental methods and their applications for process control and monitoring in the chemical industry. ; On-line techniques: Continuous flow analysis (CFA), flow injection analysis (FIA) and dynamic process analysis. ; On-line instruments, apparatus, analyzers, sensors (pH meters, ion-selective electrodes, oxygen meters, conductivity meters, CNS analyzers, TOC). Review of main characteristics: high accuracy at low concentrations, short response time, alarm (loss of sample, reagent loss, exceeding the scope of compensation, loss of power, the housing temperature), a comparative analysis of parallel integrated reference system. ; On-line optical apparatus: refractometers, photometers. ; Chemical sensors: optical, semiconductor, gas, piezoelectric. ; Combined, coupled techniques and other techniques. ; III. THE APPLICATION ; The application of chemical methods to control and process monitoring: Monitoring of technological processes in the chemical industry (production process of drinking water systems, wastewater treatment systems, system for obtaining ultra pure process water), air purification. ; ; |
