Problems solved by technology

However, with the extension of operation time and the decline of equipment performance, the desulfurization efficiency will inevitably decrease. At the same time, due to the gradual increase of sulfur content in coal combustion, many wet desulfurization devices have been unable to meet the increasingly stringent environmental protection standards.
[0003] Although the technical transformation of the original desulfurization device can improve the performance of the device, its cost often reaches more than 50% of the original device cost

Abstract

The invention relates to the field of chemical engineering and discloses a desulfuration additive and a manufacturing method thereof. The desulfuration additive comprises, by weight, 15% of benzoic acid, 20 to 30% of adipic acid, 10% of sodium benzoate, 10 to 20% of sodium glycollate, 5 to 10% of sodium acetate, 10 to 15% of magnesium oxide, and 15 to 20% of magnesium sulfate. The desulfuration additive greatly improves desulfuration efficiency, appropriately reduces energy consumption and improves by-product gypsum quality under the premise of no reconstruction of the existing device. The desulfuration additive provides a novel choice for the power plant.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a flue gas desulfurization additive. Background technique [0002] Limestone wet desulfurization technology is currently the most widely used desulfurization process in China, with the highest desulfurization efficiency and the most stable operation, accounting for more than 90% of the desulfurization devices currently built in China. However, with the extension of operation time and the decline of equipment performance, the desulfurization efficiency will inevitably decrease. At the same time, due to the gradual increase of sulfur content in coal combustion, many wet desulfurization devices have been unable to meet the increasingly stringent environmental protection standards. . [0003] Although the technical transformation of the original desulfurization device can improve the performance of the device, its cost often reaches more than 50% of the original device cost. Theref...
