Japan is the first in the world to introduce a seawater-method flue gas desulfurization system that uses seawater as an absorbent without using lime or other chemicals commonly used in conventional methods. Overseas, demand for flue gas desulfurization facilities is growing in line with increasing concerns over air pollution. Under these market circumstances, Seawater Flue Gas Desulfurization (SWFGD) systems have been drawing keen attention, as these systems help to significantly reduce equipment & operation costs.
