Nonionic Polymer Flocculant Storage — Uncharged Polyacrylamide Tank Selection

Storing Nonionic Polymer Flocculant? Start Here

If you're dealing with nonionic polymer flocculants, you're likely in industries like coal preparation, oil and gas, or salt-brine processing. These polymers are uncharged, making them ideal for high-ionic-strength water where other polymers might fail. They come in various forms, such as oil-based emulsions, water dispersions, or dry powders. Understanding the right storage solution is crucial to maintain their effectiveness and ensure safe handling.

Can you store it in a poly tank?

Yes, you can store nonionic polymer flocculants in polyethylene tanks. High-density polyethylene (HDPE) and cross-linked polyethylene (XLPE) are standard choices for both bulk and day-tank storage. Ensure that fittings and seals are compatible, with polypropylene fittings and Viton seals being recommended for emulsion service.

Mind the Temperature

For outdoor storage, especially in industrial or remote oil-and-gas locations, consider heated tanks. Temperature fluctuations can affect the polymer's properties, so maintaining a stable environment is key to preserving its flocculating performance.

The safety that actually matters

• Use Viton seals for emulsion service to prevent swelling and leaks.
• Ensure tanks are compatible with petroleum-derived carrier oils.
• Consider heated tanks for outdoor storage to prevent temperature-related issues.

Common questions

What materials are compatible with nonionic polymer flocculants?

HDPE, XLPE, and polypropylene are standard for storage and fittings. Use Viton for seals.

Can I use these polymers in high-ionic-strength water?

Yes, nonionic polymers perform well in high-ionic-strength environments where charged polymers fail.

Do I need a heated tank for storage?

If storing outdoors, a heated tank is advisable to maintain consistent polymer performance.
