Arguably the most important unit operation in a refinery, Melt Liquor Clarification requires a system that excels in removing cloudiness and colour from the product.
SUGAR HANDLING AND LIQUOR CLARIFICATION
In sugar processing there are several stages of clarification and filtration to ensure the best possible quality in the final product. Melt liquor clarification removes cloudiness (turbidity) and colour from the melt liquor, allowing for filtration and subsequent secondary decolourisation processes.
At FPE Global we are experts in designing systems that lead to high quality final products while reducing time and costs for production. One area in which we have excelled is melt liquor clarification.
THE FPE GLOBAL SOLUTION
The FPE Liquor Clarification Process uses phosphatation, flocculation and floatation techniques to removes turbidity and colour from melt liquors. This allows for the removal of colloidal particles and suspended solids, which would otherwise pass through conventional filtration.
Clarified liquor which passes through our process has a brilliance that surpasses liquor that has been treated by filtration alone.
BENEFITS OF FPE LIQUOR CLARIFICATION
As our systems are bespoke we can tailor them to your exact operation. Below is information on the general operating parameters for the FPE Liquor Clarification Process.
Contact our team to find out the specific solutions we can develop for you.
- Turbidity removal of 90% compared to the raw melt liquor
- Colour removal of 35% to 70%, depending on the colour of the melt liquor and the optional decolourant used
- A reduction in the installed filtration area
As with all of our products we focus on using the latest technology to deliver the best user experience. Our process and chemical dosing are automatically controlled via a PLC based control panel with a colour touchscreen HMI.
|Liquor brix||62 to 69|
|Liquor temperature||82 to 88 oC|
|pH||Typically 7.2 to 7.6|
|Quantity of scum produced||Typically 400 litres per 100 tonnes sugar solids|
|Phosphoric Acid at 85% concentration||28 litres per 100 tonnes sugar solids|
|Hydrated Lime||48 kg per 100 tonnes sugar solids|
|Flocculant||1 kg per 100 tonnes sugar solids|
|Decolourant (optional)||Typically 30 kg per 100 kg sugar solids|
|Space Required||For a 1200 tonnes per day sugar refinery a total of 8 bays of 6m x 6m across 2 floor levels would provide a comfortable area. This would also include a control room.|
