Decreasing off-spec batches through deviation tracking

Produced batches often need to meet specific quality criteria depending on the product grade. In TrendMiner, dashboards can be used to monitor the different types of batches produced. For example, batches can be categorized by parameters such as product grade or quality. This provides a clear, real-time overview of how many batches of each category were produced over a user-defined time period. As an example, we’ll use lab quality data from a polymer production process. The plant produces three different product grades, and quality is evaluated based on viscosity measurements.

Early Detection of Heat Exchanger Fouling

Improve asset availability and energy efficiency with self-service analytics 📌 BackgroundIn many process-driven industries, heat exchangers play a crucial role in maintaining efficient thermal operations. For example, process gases exiting a shell-and-tube heat exchanger are often routed to downstream equipment like baghouse filters, which are subject to strict temperature limits. To prevent safety risks or equipment damage, conservative temperature thresholds are often used—typically set well below actual specification limits.However, over time, systems may experience efficiency losses due to fouling, which can increase outlet temperatures and push operations closer to critical thresholds. Being able to detect and address fouling at an early stage is key to maintaining asset availability and optimizing energy use. ⚙️ ChallengeFouling inside heat exchangers reduces thermal efficiency, leading to higher outlet temperatures and potential process deviations.To ensure safe and optimal ope

Avoid product contamination through monitoring of zero-emission mechanical seals

For rotating equipment, we need to seal off moving components with mechanical seals that use a barrier fluid. There is no way to seal off moving components perfectly so there will always be some leakage. If product leakage to the environment is unacceptable (typically for SHE reasons), a zero emission seal needs to be used. For zero emission seals, there can only be leakage from the barrier fluid into the product, which is why a barrier fluid that is under higher pressure than the pumped fluid needs to be used that is compatible with the product. After all, at least some of this barrier fluid will end up in the product. A classical example of this is the usage of N2 as a barrier fluid to natural gas.Mechanical seals are common but critical components, and they can be monitored quite easily in TrendMiner as the monitoring criteria are simply value-based. We can sometimes use a value-based search directly, but if we need to compare two measurement (e.g. to ensure a difference in pressure

Calculating median value using custom calculation (tag builder)

BackgroundThis use case is centered on finding the median value of a collection of tags. In TrendMiner, it is simple to calculate the mean or average value of a set of tags. This can be done in our formula tag builder. In some cases, however, the median value proves to be more useful of a central statistic than the mean. For example, consider a furnace where there are multiple thermocouples measuring the same point temperature. If one of these thermocouples were to malfunction and read a very high or very low value, the mean value will be skewed high or low, respectively. When outliers exist in the data, the median value proves to be a useful central statistic. ChallengeThere is no built-in function in formula tag builder for calculating the median value of a collection of tags. A simple, manual formula can be created to find the median for a collection of two or three tags; however, the manual formula grows exponentially when additional tags are added.
