Higher alumina yield through improved precipitation and fines recovery
Less DSP (sodalite) scale for cleaner heat exchanger
Less hydrate scale for cleaner, more efficient washers
Better heat transfer for improved energy performance
Cleaner Bayer liquor for steadier precipitation
More uptime with fewer cleaning interventions
Easy low-ppm dosing with seamless integration
Application
Where / How FLOMIN™ AL is typically used
FLOMIN™ AL products are typically applied across the main stages of the Bayer process, from bauxite handling systems to refining circuits. Depending on site configuration and operating constraints, solutions can be introduced in bauxite conveying and transfer zones to stabilize wet material flow, in precipitation and tertiary thickening to improve hydrate fines recovery and settling, and in spent liquor circuits upstream of heat exchangers to control DSP scale and protect heat transfer performance. The range is also used in washer circuits operating under high supersaturation to prevent hydrate deposits and sustain recovery, and in clarification stages to remove dissolved organics that can destabilize precipitation and increase caustic consumption.
All FLOMIN™ AL products are designed for low-ppm dosing and continuous injection using standard dosing systems, enabling easy implementation without mechanical modifications.
Frequently Asked Questions
Everything you need to know about FLOMIN™ AL
FLOMIN™ AL is designed to deliver measurable operational gains across the Bayer process, including higher alumina yield through improved precipitation performance and fines recovery, better equipment uptime through scale control, improved heat transfer efficiency supporting lower energy losses, and longer maintenance intervals through reduced deposit formation and fewer cleaning interventions.
The portfolio supports yield improvement by enhancing hydrate precipitation performance, promoting better fines capture and settling, and improving liquor quality in key stages. This helps retain more alumina in the process and strengthens overall production efficiency.
By helping keep heat exchanger surfaces cleaner through targeted scale control in spent liquor circuits, FLOMIN™ AL supports stable heat transfer performance. This contributes to improved thermal efficiency, more consistent operating conditions, and reduced energy penalties linked to fouling.
FLOMIN™ AL helps increase operational continuity by improving wet bauxite flow behavior in handling systems, supporting stable washer performance under demanding conditions, and reducing deposit-related interventions in critical circuits. The result is smoother operation and fewer disruptions to production schedules.
FLOMIN™ AL solutions are applied at strategic points across the refinery, including bauxite handling and transfer zones, precipitation and tertiary thickening stages, spent liquor circuits upstream of heat exchangers, washer circuits, and clarification stages. This multi-stage coverage enables targeted improvements where they create the highest operational value.
Yes. The FLOMIN™ AL range is designed as a portfolio approach, allowing refineries to target several performance levers simultaneously—such as yield, scaling control, energy efficiency, and liquor quality—based on their circuit configuration and operational priorities.
FLOMIN™ AL products are designed for low-ppm dosing and integration through standard dosing systems. This supports practical implementation and fast deployment within existing operating routines.
