Control challenges of catalytic devices
Thread Content
In the catalytic production process, what are the key points and challenges regarding instrument control (including control loops and critical process control points)? Thank you
It mainly involves device self-protection and logical control of large-scale units.
1. First, it is necessary to understand the principles of some basic control loops, such as special or complex control loops like cascade control, hierarchical control, override control, and selective control. 2. Regarding parameters, distinguish between primary and secondary ones, so as to focus on the key aspects in case of accidents or problems. 3. When making adjustments normally, pay attention to the relationships and logic among various parameters – which parameters will be affected by changing one parameter, and how exactly? 4. For the parameter tuning of the control circuit, there are some empirical parameters that can serve as a reference, but it is best to do so based on the specific usage of the device.
The most important aspect of instrument control is to ensure that the data measured by the instruments is absolutely accurate. Assuming the interlock logic is correct, it is necessary to verify that the regulating functions of each instrument are always in good working order. By focusing on these points, the instruments can serve as vital tools for monitoring production processes.
