Good news! Lideheng’s “High-Temperature, High-Sulfur-Capacity Desulfurization Process and Equipment for Blast Furnace Gas” has been recognized as Beijing’s first major technical equipment of its kind.

Recently, our company’s independently developed “Blast Furnace Gas Desulfurization Process and Equipment with Wide Temperature Range and High Sulfur Capacity” has successfully passed the Beijing Municipal Certification for the First (Set) Major Technical Equipment and has been included in the “Beijing Municipal Catalog of the Fourth Batch of First (Set) Major Technical Equipment for 2025.”
This technology has developed an integrated blast furnace gas desulfurization process—featuring multi‑stage pretreatment combined with long‑duration hydrolysis—that operates over a broad temperature range and accommodates high sulfur capacities. It expands the operating temperature window of the gas desulfurization system and boosts the sulfur capacity of the desulfurizing agent to 30–40%. Key equipment, including a low‑pressure annular radial tower and online automatic dosing and discharge systems, has also been engineered. Following desulfurization, the total sulfur content of the blast furnace gas (expressed as elemental sulfur) is ≤15 mg/Nm³. The resulting process is advanced, energy‑efficient, and operationally stable, and was previously recognized by an expert appraisal committee led by Academician Hao Jiming as reaching an internationally advanced level in the field of fine desulfurization for blast furnace gas.

Currently, this technology has been successfully commissioned at numerous enterprises, including Guangxi Iron & Steel, Baowu Heavy Steel, and Quzhou Yuanli. All units are operating stably, with remarkable desulfurization performance, marking another major breakthrough for our company in core‑technology innovation and industrial application. We will continue to be driven by innovation, providing customers with more efficient and cost‑effective environmental solutions, and contributing Lideheng’s expertise to the industry’s green and low‑carbon transformation.
