In the petroleum refining process, the Fluid Catalytic Cracking (FCC) unit is the core component; however, it also generates a significant amount of sulfur-containing flue gas. How can refineries remove sulfur oxides from flue gas efficiently and economically to meet increasingly stringent environmental regulations? Magnesium Oxide (MgO), as a key component of the new generation of sulfur transfer additives, is standing out due to its unique advantages. Messi Biology focuses on the R&D and production of high-quality magnesium oxide, and its products perform excellently in the field of sulfur transfer additives, becoming a reliable partner for refineries in their environmental upgrades.
Magnesium Oxide: The “Chemical Catcher” of Sulfur Transfer
The core principle of sulfur transfer additives is that within the regenerator of the FCC unit, magnesium oxide reacts chemically with sulfur oxides (SOx) in the flue gas to form stable magnesium sulfate (MgSO₄). Subsequently, in the reactor environment, the magnesium sulfate is reduced and releases hydrogen sulfide (H₂S), which is then processed in the subsequent sulfur recovery unit. In this process, magnesium oxide plays the role of an efficient “catcher” and “carrier.”
Magnesium Oxide: The Foundation of Superior Performance
Meixi Biological deeply understands the rigorous requirements that sulfur transfer additives place on magnesium oxide performance. Its products offer significant advantages:
- Ultra-High Purity, Multiplied Efficiency: “Meixi” magnesium oxide is refined using advanced processes, boasting extremely high purity (MgO content > 98.5%) and minimal impurity levels. This means that a unit mass of magnesium oxide can adsorb and convert more sulfur oxides, significantly increasing sulfur transfer efficiency, reducing the amount of additive required, and lowering overall costs.
- High Activity, Rapid Reaction: The product features an excellent specific surface area (>100 m²/g) and a specialized pore structure. This provides a vast contact surface and fast reaction channels for SOx gases, ensuring that the sulfur transfer reaction is thorough and efficient within the limited high-temperature residence time of the regenerator.
- Structural Stability, Long Service Life: “Meixi” magnesium oxide demonstrates outstanding structural stability in high-temperature regeneration and steam environments. Its strong anti-sintering capability effectively slows down particle agglomeration and pore collapse caused by high temperatures. This allows it to maintain high activity over the long term, extending the additive’s service life and reducing the cost and operational burden of frequent replacements.
- Uniform Particles, Smooth Fluidization: Strictly controlled particle size distribution ensures an excellent match with the main FCC catalyst particles. This ensures uniform fluidization within the unit, avoiding bias flow or excessive loss, and guaranteeing stable and reliable sulfur transfer performance.
