SDS Dry Desulfurization

Product Overview

The TONGZHENG SDS dry desulfurization EPC project provides a complete turnkey solution for ultra-low-emission desulfurization and dedusting in the steel industry. The SDS dry desulfurization process offers several advantages, including high desulfurization efficiency, no temperature drop, water-free operation, low investment cost, a small footprint, low by-product generation, low power consumption, no corrosion, and simple equipment with easy operation and maintenance. It also produces a relatively small amount of desulfurization by-products with a high sodium sulfate content. The process provides excellent operational flexibility: the start-up and shutdown of the desulfurization system do not affect the continuous operation of the furnace, and its operating load range is well matched to the furnace load range, ensuring reliable, stable and continuous operation of the desulfurization system.

What Is an SDS Dry Desulfurization EPC Project?

SDS dry desulfurization is a dry flue-gas desulfurization technology in which a sodium-based dry sorbent is injected into the flue-gas stream, where it reacts with sulfur dioxide (SO₂) to form solid desulfurization by-products with a high sodium sulfate content. The solids are carried with the flue gas and collected together with the dust in the downstream baghouse filter, so the process causes no temperature drop and requires no water, avoiding corrosion and wet-wastewater treatment. As an EPC project, the scope typically covers engineering design, equipment supply, installation and commissioning as a complete turnkey system, enabling steel plants to meet ultra-low-emission requirements for SO₂ and dust with a compact footprint, low investment and simple operation.

Applications
