Dosing unit minimises washout in process and flue gas analysis

Sep 07 2020 Read 287 Times

Bühler Technologies have recently introduced a new innovation to continue with their mission to meet the highest standards in emission analysis.

Many are familiar with the problem: In extractive analysis of process and flue gases, reliable and constant reduction of sample gas humidity is essential. But the solution to reduce humidity with cooling reduces the concentration of water-soluble gas components (such as SO2).

The EMIDos dosing unit offers a solution to minimising this washout. A premixed acid is fed into the heat exchanger at a constant rate to saturate the excreted water content. A metal bracket enables wall-mounting the complete unit. The modified cover makes the acid container, sold by Bühler, easy to connect. The specifically designed connecting adapter on the dosing pump and the heat exchangers ensure the feed time of the acid in the dosing line is low. A capacitive sensor to monitor the acid level completes the concept the Bühler Technologies engineers had in mind.
