Secondary meter detection of quality parameters in production control
Thread Content
In current chemical production, there are many quality parameters (such as conversion rate, esterification rate, Mooney viscosity, melt index, etc.) that are crucial factors in determining the quality of products. By controlling these parameters properly, high-quality and stable products can be manufactured. However, due to the complexity of chemical production, no instruments exist that can directly measure these parameters online. Currently, by developing secondary functions for the instruments, existing signals from the production site (temperature, pressure, flow rate, etc.) are utilized; additional measurement points are added at appropriate locations depending on the specific project. Mechanism modeling is carried out using physical and chemical methods, and a model that is uniquely suitable for the customer’s actual process design is developed. An effective measurement of these parameters is achieved through a database platform.
What does your post mean? Are you looking to learn about in-process monitoring/online analysis instruments? ? ? For online monitoring instruments, Mettler does a good job in this area; they can measure things such as conductivity, pH, and turbidity in the medium being tested. In more advanced models, it’s even possible to analyze certain components within the material… The choice depends on the specific process requirements, as our instruments are designed to serve those processes.
The original poster is referring to a secondary calculation, not a direct measurement
There was a situation like this: our vacuum potassium carbonate desulfurization tower requires steam, and the amount needed is calculated based on the temperature difference between the inlet and outlet. The majority of the steam needed comes from waste heat, while any shortfall is covered by the steam pipeline system
If it can be measured directly, why is conversion needed? However, conversion can save money……
