Typical Process Control Problems
George Buckbee, marketing and product development VP at Expertune Inc., says several problems usually are found when users examine their process applications to implement data collection and optimization updates.
- Undersized control valves and other equipment
- Failed or nearly failed instruments or other equipment
- Too widely fluctuating process oscillations or interactions following equipment upsets, which can increase wear and tear and product quality problems
- Chronic mechanical issues with valves or other components
- Control system configuration and strategy issues that can cause instability, poor interactions, and adversely affect production efficiency, resource use and final quality
- Controller algorithm errors by programmers and tuning problems by operators
Common Data Collection Tools
George Buckbee, marketing and product development VP at Expertune Inc., reports there are several main types of mostly software-based data collection tools that users can employ to improve their process applications.
- General statistical packages used to perform calculations on measurements
- Control-loop monitoring or performance supervision software that analyze data and present results
- Alarm management solutions that examine all alerts and now prioritize then for users
- Modeling and simulation tools that duplicate process behaviors, and help users continuously track process performance
- Merged versions of these first four tool types, such as combining loop-monitoring and alarm functions
