NINGBO INNO PHARMCHEM CO.,LTD. is a trusted supplier of essential chemical compounds that drive various industrial sectors. Magnesium Bisulfite (CAS 13774-25-9) stands out as a compound with significant industrial utility, particularly in the pulp and paper industry and environmental protection initiatives. Its unique chemical properties as a reducing agent and oxygen scavenger make it a valuable asset in processes that require precise chemical control and environmental compliance.

In the pulp and paper industry, Magnesium Bisulfite plays a pivotal role as a component of the cooking liquor in sulfite pulping. This process is crucial for separating lignin from cellulose fibers to produce paper pulp. The chemical recovery cycle associated with magnesium-based sulfite pulping is designed for high efficiency, aiming for a closed-loop system where magnesium and sulfur compounds are reclaimed and reused. Magnesium Bisulfite is regenerated in this cycle by absorbing sulfur dioxide (SO₂) from flue gas. The precise control of the bisulfite concentration and pH is critical for optimizing pulp quality, maximizing chemical recovery, and minimizing the formation of undesirable precipitates like magnesium sulfite, which can hinder process efficiency.

Beyond its application in pulping, Magnesium Bisulfite is a key player in environmental protection, specifically in Flue Gas Desulfurization (FGD) systems. Industrial facilities, particularly power plants, often employ magnesium-based wet scrubbing technologies to remove sulfur dioxide (SO₂) emissions from their flue gases. In these systems, a slurry of magnesium hydroxide or oxide reacts with SO₂ to form magnesium sulfite, which is subsequently oxidized to magnesium sulfate. Magnesium Bisulfite can be involved in this complex equilibrium, contributing to the efficient capture of SO₂. The use of magnesium-based sorbents offers advantages such as higher SO₂ removal efficiencies and better manageability compared to traditional calcium-based systems. NINGBO INNO PHARMCHEM CO.,LTD. provides the high-purity Magnesium Bisulfite necessary for these demanding industrial applications, ensuring consistent performance and regulatory compliance.

The compound's utility as a reducing agent and oxygen scavenger also extends to water treatment applications, where it helps prevent corrosion in pipelines and storage tanks by reacting with dissolved oxygen. This broad spectrum of industrial uses highlights the versatility of Magnesium Bisulfite. For businesses seeking a reliable supplier of this critical industrial chemical, NINGBO INNO PHARMCHEM CO.,LTD. offers consistent quality and expert support to meet diverse manufacturing needs.
