Disposal of Spent Sorbent from Dry FGD (Flue Gas Desulfurization) Processes

摘要

The report gives results of a study of sintering and leaching mechanisms of fly ash/spent sodium sorbent mixtures from a dry injection flue gas desulfurization (FGD) process. It includes an estimate of the economics of pelletizing and sintering to handle the fly ash and spent sorbent from a 500 MW power plant burning low sulfur western coal using a dry injection FGD process.
