Multiphase level measurement system simplifies separation process monitoring

Sep 07 2020 Read 755 Times

Separation processes occur in many industries, whereby primarily interface and multiphase level measurements are applied in refineries and chemical plants, e. g. on separator vessels. Where other measuring methods fail and cannot withstand the extreme conditions prevailing in such processes, radiometric measuring systems provide reliable results. Its principle is based on the attenuation of gamma radiation when penetrating materials, such as the vessel or its contents.

Berthold’s radiometric measurement systems are used to monitor more than two phases or interfaces that are not clearly defined. Depending on the process, a transition phase changing in height or only very small differences in density of the individual phases must be expected, also build-ups on the vessel walls or installations inside the vessel are also not uncommon in separation processes. With Berthold’s EmulsionSENS multiphase level measurement system, separating layers are reliably monitored and the dependent process can thus be optimally controlled. Thereby, not only the interfaces between two phases can be localised, but also the measurement of density profiles in more complex processes is possible. In this way, the heights of the different product layers inside the vessel can be mapped and so the characteristics of a transition phase, e.g. emulsion, can also be monitored.
