Polish fertilizer and chemicals company Grupa Azoty SA, Tarnów, has completed commissioning work on the flue gas desulfurization plant for boiler K-5.
The flue gas is desulfurized in a wet magnesium process, and the SO2 absorbed in a suspension of calcined magnesite, the company said in a March 16 statement.
The product of the desulfurization process will be magnesium sulfate heptahydrate, which is used in agriculture as a magnesium fertilizer or as a component of compound fertilizers, Azoty said.
Azoty highlighted that obtaining this product in the flue gas desulfurization process offers the company an opportunity “to take advantage of the synergies between its energy segment and fertilizer production.”
