Technology – Elixsys Inc.

Flue Gas Desulfurization (FGD) materials are produced by scrubbers that are used to capture sulfur from flue gas. FGD gypsum is one of the more common FGD materials. Pulverized Coal (PC) Ashes – These ashes are produced by plants that pulverize the coal and burn it with heated air to produce energy. PC ashes typically contain little or no sulfur.
