Flue gas scrubber

Lime milk density measurement

To lower their emissions, conventional power stations operate complex flue gas scrubbing systems. Many of these systems use a “wet method”, in which lime in the form of a lime milk suspension is used as a “detergent”. The untreated flue gas is sprayed with the lime milk suspension in a scrubbing tower. The sulphur dioxide contained in the exhaust fumes is largely absorbed through a chemical reaction, the end product of which is gypsum. For an efficient flue gas scrubbing process, it is important that the concentration – therefore the density – of the lime milk remains constant.

Density measurement with MINITRAC 31

The fine particles in the lime milk are very abrasive, so a non-contact density measurement with MINITRAC 31 is the ideal solution. The instrument measures with high precision directly and contactlessly through the pipeline without any intervention in the closed system being required.

Source holder VEGASOURCE 31

This source holder serves as a receptacle for the radioactive source. It offers the best possible shielding and allows the focussed radiation to exit in only one direction. The medium, the pipeline and the source holder itself are not contaminated by the weak gamma radiation emitted.
