A 9-month program at the 194 MW. Southwest Power Plant (SWPP) of City. Utilities, Springfield, MO, demonstrated. the effectiveness of adipic acid and. dibasic acids, the latter by-products. obtained during production of the former. The test program examined the effect of. adipic acid addition to a limestone FGD.

The handbook, intended for use of utility project managers and project engineers, provides guidance in selection, installation, and operation of a limestone FGD system, covering all phases from inception of the project through design, procurement, operation, and maintenance of the system. It gives detailed accounts of utility experience with …

The FGD processes investigated in- clude conventional lime/limestone, magnesia enhanced limestone, dibasic acid (DBA) enhanced limestone, and limestone with two-tank forced oxida- tion. Data indicate that the effects of Cl~ on the performance of the absorber are a function of cations associated with Cl~ and scrubber operating conditions.

Wet limestone scrubbing has high capital and operating cost due to the handling of liquid reagent and waste. Nonetheless, it is the preferred process for coal-fired electric utility power plants burning coal due to the low cost of limestone and SO2 control efficiencies from 90% up to 98% (Schnelle, 2002).

Unoxidized Lime/Limestone FGD products are thixotropic sludges (consistency of toothpaste—may liquefy when shaken) Difficult to dewater. Require some sort of processing or admixture such as fly ash or lime to achieve moisture levels that can be handled. Cannot be easily stored, transported or spread with conventional agricultural equipment.

The report describes flue gas desulfurization (FGD) systems and the design and operating parameters that are monitored to ensure proper operation. It explains how these parameters are varied to accommodate changing boiler loads and fuel characteristics, and describes the control of parameters to prevent such problems as …

The report gives results of a comparison of results from a recent forced-oxidation limestone flue gas desulfurization (FGD) process evaluation and those from a conceptual design and economic evaluation of a sodium/limestone double-alkali FGD process, based on recent EPA-sponsored pilot-plant and prototype test work.
