The following pollutants chemical elements Aluminum, Arsenic, Boron, Copper, Mercury and Selenium, found in power plant flue gas desulfurization wastewaters – with the focus on flue gas desulfurization (FGD) wastewater.
Experts on scrubbers and representatives of the Israel Electric Corporation had concluded its review of the environmental and economic aspects of different scrubber technologies. The review was undertaken in light of plans by the Israel Electric Corporation to install a flue gas desulfurization (FGD) plant in its Ashkelon power station.
As part of the process, an environmental comparison of two different FGD Flue Gas Desulphurization processes was undertaken wet limestone and seawater.
The wet limestone method transforms SO2 emissions into gypsum, after reaction with limestone. The seawater technology neutralizes SO2 using seawater with the byproducts emitted to the sea.
Although advantages and disadvantages were found in both methods, the expert committee opted for the limestone technology. Inter alia, the decision was based on the fact that the gypsum produced in this process will be absorbed by the local market, and that the technology is based on positive worldwide experience. The committee further recommended that recovered water be used for the operation of the limestone scrubber system. The Israel Electric Corporation has committed to abide by any recommendation made by the Ministry of the Environment.
