Glycerine Storage — Pharma, Food, Biodiesel Byproduct, Cosmetics

Storing Glycerine? Start Here

Glycerine is a versatile and benign chemical used in everything from pharmaceuticals to biodiesel production. If you're dealing with glycerine storage, the good news is that it's quite straightforward. Whether it's crude, technical, or USP grade, the main focus is on maintaining purity and temperature to ensure quality. Proper storage can mean the difference between a valuable product and a costly disposal problem.

Can you store it in a poly tank?

Yes, glycerine can be safely stored in polyethylene tanks. High-density polyethylene (HDPE) is suitable for all concentrations and temperatures up to 140°F. This makes HDPE tanks a reliable choice for glycerine storage across various industries.

Temperature Management is Key

One critical aspect of storing glycerine is managing its viscosity, especially in colder climates. Glycerine becomes significantly more viscous as temperatures drop, making it difficult to pump. If you're storing glycerine outdoors in a northern climate, consider heat-tracing your tanks to maintain a minimum temperature of 10°C for smooth operation.

The safety that actually matters

• Ensure tanks are made from compatible materials like HDPE.
• Maintain proper temperature control to prevent viscosity issues.
• Follow sanitation protocols for food and pharmaceutical grades.

Common questions

What materials are compatible with glycerine storage?

HDPE, LDPE, and MDPE tanks are all suitable. Use EPDM, Viton, Buna-N, or silicone gaskets.

How do I prevent glycerine from becoming too thick to pump?

Use heat-tracing on tanks and lines to keep the temperature above 10°C, especially in cold climates.

Is special sanitation needed for USP-grade glycerine?

Yes, while the tank material remains the same, sanitation and documentation are crucial for maintaining USP-grade purity.
