Froth Factor for Pump Sizing

The 'froth factor' is a measure of the air contained in the froth. It is quantified by filling a measuring cylinder or bucket, of known volume, with froth and measuring the froth column. After air dissipation the remaining water and solids volume is measured. The ratio of the original volume of froth to the remaining combined volume of ...

How to Conduct a Successful Focus Group Discussion

Keep the number of questions reasonable (under 10, if possible). This prevents the participants from getting confused or worn out by a long discussion. Keep the questions simple and short. FGD participants won't get the chance to see the questions like in a survey. Ensure that the wording on questions is clear.

Flue gas treatment for CO capture

plants already have units to remove air pollutants prior to CO 2capture, such as FGD, SCR, and ESP. However, some pollutants will be absorbed in the solvent with the CO 2and can lead to the formation of heat stable salts. The FGD process may need to be improved to reduce SOx emissions to an acceptable level for post-combustion capture.
