    Measurement requirements. The FGD units use the limestone/gypsum wet scrubbing process. This involves lime slurry prepared in an agitated reactor that is pumped to the top of the absorption tower, where it is sprayed into the rising flue gas by nozzles. As a result, SO x in the flue gas stream is washed out (absorbed). Subsequently, a ...

    Jul 18, 2014· Gypsum is a soil amendment, and it doesn't impact soil pH. Lime corrects low pH in soil, but it has low solubility. Fall is the best time to apply lime so that it has time to react in the soil. Lime is sold based on its grade, calcium carbonate equivalent and grind size. The smaller the grind size, the more reactive it is.

    Loss on ignition (LOI) is a test used in inorganic analytical chemistry and soil science, particularly in the analysis of minerals and the chemical makeup of soil. It consists of strongly heating a sample of the material at a specified temperature, allowing volatile substances to escape, until its mass ceases to change.This may be done in air, or in some other reactive or inert atmosphere.
