Continuous Process Control: Applications of pH Control is part four of the Continuous Process Control four-part training series.
Produced in conjunction with ISA The Instrumentation, Systems, and Automation Society (ISA™) the course teaches the basics of pH and how the efficiency of a process is influenced by this factor. pH is one of the most difficult process variables to control, so an understanding of the chemistry and characteristics of pH is important. In addition, students will examine the equipment used in a pH control system and some of the factors that must be considered in the selection and utilization of various types of equipment.
Course objectives include:
- Define pH
- Describe the basic characteristics of pH and how these factors can influence pH control
- Define the chemical breakdown of pH and how the pH scale should be interpreted
- Describe the factors affecting pH control, such as rangeability, nonlinearity, and sensitivity of pH
- Describe how equipment and hardware can affect pH measurements in a pH control system
- Recognize the conditions of the pH adjustment process and the outcome of this process.
- Importance of pH Control
- What is pH?
- Factors Affecting pH Control
- Hardware Selection for pH System
- pH Control Schemes
- Example of a pH Control System
