Managing Challenges in Bulk Material Handling of Caustic and Acidic Chemical Powders: UniTrak's Innovative Solutions

May 7, 2024

The handling of caustic and acidic chemical powders poses significant challenges and risks in chemical manufacturing and processing. From corrosive properties to potential hazards during conveying, chemical processors face many concerns. However, with the right equipment features, innovations, and customization options, these challenges can be effectively managed to ensure safety, efficiency, and product integrity.

Understanding the Challenges and Risks

Corrosion: Caustic and acidic powders can corrode conventional material handling equipment, leading to equipment degradation, increased maintenance costs, and potential safety hazards.

Material Containment: Caustic and acidic powders may react with the atmosphere, leading to contamination or hazardous emissions if not properly contained during handling and conveying.

Explosive Properties: Some chemical powders, when exposed to certain conditions, can become explosive, posing a significant safety risk during conveying operations.

Abrasion: Abrasive nature of certain chemicals can cause rapid wear and tear on conveying equipment, leading to frequent replacements and downtime.

Common Caustic and Acidic Powders in Chemical Processing

Caustic Materials

  - Sodium Hydroxide (NaOH)

  - Potassium Hydroxide (KOH)

  - Calcium Hydroxide (Ca(OH)₂)

  - Ammonium Hydroxide (NH₄OH)

Acidic Materials

  - Sulfuric Acid (H₂SO₄)

  - Hydrochloric Acid (HCl)

  - Nitric Acid (HNO₃)

  - Phosphoric Acid (H₃PO₄)
