K-Patents has released a new application note on bulk liquid chemicals identification in loading and unloading operations. Chemical plants may deal with multiple unloading stations, thus, fast and reliable interface detection is necessary for product identification and safe unloading operation.
Combining an interface detection device with automatic controls can minimize transmix of products, reduce waste, reduce the filling/ unloading times, decrease safety risks, reduce sampling and minimize operator errors.
Refractive index can be a reliable method for identifying a chemical before unloading it into receiving tank as it can be used to "fingerprint" the product for identification.
