FGD (Flue Gas Desulfurization) is a technology used for removing sulphur from the exhaust flue gasses emitted in coal- and oil-burning power plants. In order to optimize the desulfurization process, it is important to measure the density of the process slurry (lime stone) in real time, so that efficiency can be improved and waste reduced.
These measurements are often done using nuclear technologies. However, to avoid complex government regulations with regards to the handling of nuclear isotopes, contact-less Rhosonics density sensors offer a reliable and comparatively cheaper solution. Furthermore, with our sensors you will avoid a lot of difficulties encountered with other types of sensors that can lead to possible damages due to complex flow paths, which may lead to either blockages or erosion.
Have a look at the SDM Slurry Density Meter. This model is regularly used for this specific application. Rhosonics instruments monitor the attenuation with ultrasonic signals, of which the density can be measured directly and in-line.
