Sodium Sulfate Production Equipment

Product Introduction

Sodium Sulfate Production Equipment employs the Mannheim process, a widely used method known for its high yield and efficiency in producing sodium sulfate (Na₂SO₄). However, traditional Mannheim processes face several challenges, such as uneven heating, incomplete reactions, high energy consumption, and inefficient sulfuric acid absorption. These issues can negatively impact product quality, operational efficiency, and increase production costs.

To address these challenges, we have implemented significant improvements to the production equipment and process. By optimizing the furnace design and materials, we ensure even heating, complete reactions, and reduced energy consumption, resulting in higher-quality sodium sulfate. Additionally, we’ve upgraded the sulfuric acid absorption system by applying new materials and advanced technology, which improves absorption efficiency, minimizes environmental emissions, and enhances product purity.

With these key innovations, our Sodium Sulfate Production Line not only delivers superior product quality but also offers energy-efficient and cost-effective operations. We provide a complete, turnkey solution from raw material handling to final product output, ensuring our customers benefit from a sustainable, high-performance production system.

Mannheim Furnace Process

The Mannheim Process for producing sodium sulfate (Na₂SO₄) is a well-established industrial method, primarily used to manufacture industrial-grade sodium sulfate. The process involves the reaction of sodium chloride (NaCl) with sulfuric acid (H₂SO₄) at high temperatures (500-600°C) to produce sodium sulfate and hydrochloric acid (HCl) as a byproduct.

Key Reaction:

2 NaCl + H₂SO₄ → Na₂SO₄ + 2 HCl

Process Steps:

1. Raw Material Preparation: Sodium chloride (NaCl) and sulfuric acid (H₂SO₄) are mixed in stoichiometric proportions to ensure the correct chemical reaction.
2. Reaction: The mixture is introduced into a Mannheim furnace, where it undergoes the high-temperature reaction, yielding sodium sulfate and hydrochloric acid.
3. Product Separation: The molten sodium sulfate is discharged from the furnace, cooled, and solidified, while the hydrochloric acid gas is absorbed in water to produce hydrochloric acid.
4. Tail Gas Treatment: Any residual gases are treated to comply with environmental regulations, ensuring minimal emissions.
