The effectiveness of silica gel bleaching sand in industrial purification processes, particularly in the oil and gas sector, is well-established. However, optimizing its performance often hinges on selecting the correct particle size, commonly referred to as mesh size. Different applications and oil types benefit from specific mesh sizes of silica gel, influencing flow rates, contact time, and adsorption efficiency. As a dedicated silica gel sand supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. provides silica gel bleaching sand in various mesh sizes to cater to diverse industrial requirements.

The Significance of Mesh Size in Adsorption

Silica gel is typically categorized by its particle size distribution, indicated by mesh numbers. A higher mesh number signifies smaller particles, while a lower mesh number indicates larger particles. The choice of mesh size impacts several critical aspects of the purification process:

  • Surface Area to Volume Ratio: Smaller particles (higher mesh) generally offer a larger surface area relative to their volume, potentially leading to faster adsorption rates and higher efficiency for certain contaminants.
  • Flow Rate and Pressure Drop: Larger particles (lower mesh) allow for higher flow rates and lower pressure drops through a packed bed of adsorbent, which is crucial in continuous processing or when dealing with viscous fluids.
  • Contact Time: The particle size influences how long the oil remains in contact with the adsorbent. Optimal contact time is essential for effective impurity removal.
  • Filtration Efficiency: While the silica gel's primary role is adsorption, particle size also affects how easily it can be filtered out after use.

Common Mesh Sizes and Their Applications

Our silica gel bleaching sand is commonly offered in the following mesh sizes, each suited for distinct applications:

  • 20-40 Mesh: These larger granules are ideal for applications requiring fast flow rates and lower pressure drops, such as the atmospheric pressure treatment of high-viscosity oils like transformer oil and heat-conducting oil.
  • 30-80 Mesh: A versatile size, this range is suitable for a broad spectrum of oils with moderate to high viscosity, including engine oil. It offers a good balance between flow rate and adsorption efficiency.
  • 40-120 Mesh: The finer particles in this range provide a high surface area and are well-suited for lower viscosity oils or processes involving medium to low pressure, allowing for more intensive purification and effective adsorption.
