Definitions

  • the cations as for example Sodium and/or Potassium, are replaced by the Magnesium cations (known Quentin process) by letting the sugar juice containing the highest molassigenic cations percolate on the ion exchange resin: in the above mentioned form.
  • a second drawback lies in current sugar juice treatment with resins in the Alkali-magnesium process.
  • This high Maghesium content prevents the traditional conversion or utilisation of molasses which, as iS known, is a high energy product.
  • the procedure regarding this invention greatly reduces, or eliminates, the aforesaid drawbackes since the clo- ride ions containing polluting effluents are totally eliminated thus obtaining molasses having a low magnesium content with the advantage of noticeably reducing the consumption of the fresh regenerating product such as Magnesium Chloride.
  • the regeneration of the depleted resins is achieved through percolation of the molasses derived from treatment of the previous sugar juice with resins and containing, as has been stated before, a high percentage of Magnesium, pro vided a proper amount of fresh reagent is added to the molasses.
  • the enclosed drawing shows a block diagram of the processing and regenerative system of the ion exchange resins in the Alkali-magnesium process according to the currently known (Quentin) process and the one according to this patent.
  • the sugar juice 1 to be purified penetrates qnd percolates in the resin column. He re the alkali-magnesium exchange takes place i.e. the Sodium and/or Potassium ions pass on to the resin while the Magnesium ions pass on to juice.
  • the processed juice 2 undergoes various subsequent treatments B (vacuum panning,crystallization, centrifugation, etc.) until crystallized sugar 3 and molasses 4 are obtained, subje cted to further transformations or uses C.
  • this molasses has a high Magnesium content.
  • Regeneration of resin is obtained by per colating-the regenerated fresh product 5, such as Magne sium.Chloride, in the depleted A' column in order to obtain the alkali-magnesium ion exchange and to regenerate the resins with magnesium ions, while the effluents 6, with a highly polluting chloride content are disthar- ged in the tanks D.
  • the regenerated fresh product 5 such as Magne sium.Chloride
  • the molasses obtained from the treatment of the juices is heated and is diluted in E and thus enters as regenerating agent the depleted column A' in which additives with a suitable percentage of fresh regenerative agents 5 have been added.
  • the molasses and the fresh regenerating agent lose their magnesium ions to the resin while being enriched with Sodium and/or Po tassium ions.
  • the effluent molasses after concentration in F can be subjected to further treatments or utilization C, facilitated by the lower magnesium content.
