Project overview
One of Thailand’s largest sugar refineries aimed to improve the efficiency of its decolourisation process and achieve lower colour levels in treated syrup.
Thermax optimised the resin configuration by recommending a more effective setup, enhancing process performance. The solution resulted in improved output quality, higher treated volumes, and significant cost savings.
Challenges
- One of Thailand's largest sugar refineries was using acrylic strong base anion resin in the primary column and styrenic strong base anion resin in the secondary column for decolourising 60°C brix sugar melt. The plant operated continuously in a lead-lag mode, treating sugar melt with a colour level exceeding 600 ICUMSA. The goal was to achieve more efficient decolourisation and a lower colour level.
Solution
- Thermax recommended replacing the existing acrylic-styrenic setup with styrenic-styrenic macroporous strong base anion resins.
Result
- The new configuration led to significant cost savings and improved treated syrup volume, achieving a colour level of less than 150 ICUMSA.
