Tulsion® Specialty Ion Exchange Resins for Decolourisation of Re-melt Sugar for Refined Sugar Manufacturing

Raw sugar (C11H22O11), produced from sugarcane is brownish in colour. Specifically processed Tulsion® A-72 MP, Tulsion® A-30 MP and other resins are extensively used by sugar refineries for decolourisation of sugar melt/raw sugar.

These are highly macro porous, strong base anion exchange resins (type I), in chloride form.

They are designed considering the operating conditions and stringent purity norms of final product. Colours like 2000 ICUMSA can be conveniently treated with Tulsion® speciality resins. High macro porosity of Tulsion® resins ensures adsorption of high molecular weight colourants while the specialised backbone plays an important role in enhancing decolourising efficiency.

Depending on the concentration of colour bodies in sugar melt, one, two or three-stage process are used.

Advantages of Tulsion® Specialty Resins
  • Substitutes or reduces sulphate and phosphate treatment, which helps to produce sugar as per global norms.
  • Provides for operational ease in service and regeneration.
  • Is an effective substitute for activated carbon based decolourisation processes to achieve high cost effectiveness.
