Take the following as truth: Upgrades to existing FGD systems would include a case-by-case examination of the absorber tower, flue gas inlet, absorber gas velocity, reagent preparation, upgrade pumps, and potential changes to some internals, the type of reagent, and to the chemical processes to increase performance.
Then the following statement: "The chemical process to existing FGD systems is proprietary." is true, false, or inconclusive?
Answer: Inconclusive
