Definitions
- WO-A-92 08810 relates to a method for increasing the crystallization yield of sugar from a sweet juice. This process is based on the removal of monovalent ions before crystallization. This elimination is carried out by the use of nanofiltration which leads to a permeate which contains a substantial part of the monovalent ions, and to a retentate depleted in monovalent ions, the crystallization being performed on the retentate.
- US-A-4,115,147 has for object a process based on the implementation of tangential filtration membranes for the production of non-centrifugal nutritious sugar.
- the object of the present invention is to remedy the aforementioned drawbacks previously known methods and, to do this, it proposes a method of manufacture of granulated sugar, as defined in the appended claims.
- the process according to the invention By implementing the tangential filtration operation, it is possible to eliminate the colloidal matter present in clarified sweet juice and, to the extent that such materials are dye precursors that develop during crystallization, thus obtaining at the end of the process a crystallized sugar of lower coloring. This is particularly true in the case where the starting aqueous sweet juice is constituted by a juice of the sugar cane juice type, since the process according to the invention then allows obtaining a brown sugar with a coloration of less than 400 ICUMSA units, while conventional methods lead to the production of brown sugar with a coloring of 800 to 4000 ICUMSA units.
- the crystallization operation may be followed by a chromatography operation of said molasses to obtain a first liquid effluent depleted in sugars and a second liquid effluent enriched in sugars; such a chromatography operation fits perfectly into the process according to the invention since the prior microfiltration, ultrafiltration or nanofiltration and tangential softening operations allow substantial elimination of colloidal materials and Ca 2+ ions and / respectively or Mg 2+ usually responsible for the relatively rapid decrease in the separation power of the chromatography.
- micro-, ultra- or nanofiltration operation tangential not only eliminates the colloidal matter present in the starting sweet juice, but also to clarify this juice, i.e. to eliminate suspended matter.
- the implementation of the method according to the invention leads to a significant improvement in the overall balance of the sugar refinery with, moreover in the case where the starting sweet juice is of the sugarcane juice type, a gain in purity of the brown sugar obtained which goes from 98-99.4% (conventional process) 99.7%.
- This improvement is obtained by the implementation of an operation of microfiltration, ultrafiltration or tangential nanofiltration and an operation softening, well known techniques, simple, flexible, high yield, fast, well controlled and low operating cost.
- the implementation of the operation of microfiltration, ultrafiltration or tangential nanofiltration possibly combined with the simple clarification operation advantageously eliminates the aforementioned complex and expensive purification operations.
- the refining used in the process according to the invention for manufacturing white sugar crystallized frees itself from refining and purification operations (carbonation or phosphating) and filtration and this, thanks to the fact that the implementation of operations described above allows obtaining a brown sugar purer, less colored and containing no more colloidal matter in comparison with that obtained by conventional techniques.
- the elimination of refining operations, carbonation or phosphating and filtration is of obvious interest when you know the tedious and expensive character of the crystallization operations of the refining sewer and low product sewers.
- the advantage provided by the process according to the invention of making crystallized white sugar is therefore evident in terms of economic.
- the starting aqueous sweet juice to be treated is a juice obtained by grinding sugar cane, this juice containing sugars and organic and mineral impurities including Ca 2+ and / or Mg 2+ ions.
- this juice can beforehand, although it is not absolutely essential, be subjected to a clarification operation having the aim of eliminating the major part of the solid matters in suspension.
- it is brought by the circulation pump 1 and the conduit 2 to the upper part of a flocculation tank 3, after having been preferably heated to 70-105 ° C, for example by means of an exchanger indirect heat 4.
- this tank 3 it is mixed with vigorous stirring with a flocculating agent stored in the tank 5 and brought from the latter to the upper part of the flocculation tank 3 by a circulation pump 6 and a conduit 7.
- the tank 5 may be provided with heating means (not shown) such as an internal jacket in which a hot fluid circulates, for example hot water or steam; these heating means make it possible to bring the flocculating agent to a temperature of the order of 70 to 80 ° C.
- This agent can in particular be constituted by a slurry of slaked lime, by a cationic surfactant, in particular a compound quaternary ammonium tallow fatty acids, such as dioctadecyldimethylammonium chloride, such as NORANIUM® M2SH marketed by the French company CECA, by derivatives of the deacetylated poly-N-acetylglucosamine chitosan derived from chitin, such as PROFLOC ® 340 from the Norwegian company PROTAN BIOPOLYMER, or by a mixture of these.
- the amount of flocculating agent will usually be 0.2 to 2 g / kg of dry matter of the juice to be treated.
- the flocculation mixture is then extracted from the base of the reservoir 3 and brought by a conduit 8 into a settling tank 9 with a substantially conical base.
- the bottom of the tank 9 can be provided with a duct and an extraction pump bringing the solid deposit collected in the conical part of the tank 9 into a filtration unit (for example rotary filter), the filtrate then being brought back into the tank 9.
- the supernatant liquid (clarified juice having a turbidity of in the order of 15 to 60 NTU / Brix) in the tank 9 is extracted from the latter by a circulation pump 10 discharging into a unit 11 of tangential microfiltration, tangential ultrafiltration or tangential nanofiltration. If necessary, the supernatant thus withdrawn from the tank 9 can be reheated so that the operation in this unit 11 takes place at a temperature of the order of 70 to 99 ° C and preferably from 95 to 99 ° C.
- the membrane used in unit 11 can be of the organic type or of the mineral type (for example of TiO 2 or ZrO 2 ) and have a cut-off threshold corresponding to a molecular weight of at least 1000, good results being obtained with a membrane ultrafiltration having a cutoff threshold corresponding to a molecular weight of 300,000, as well as with a microfiltration membrane having a pore diameter of 0.1 ⁇ m.
- a membrane ultrafiltration having a cutoff threshold corresponding to a molecular weight of 300,000
- a microfiltration membrane having a pore diameter of 0.1 ⁇ m.
- use can be made for example of the KERASEP® membrane available from the French company TECH-SEP or of the FIMTEC® GR 90 PP membrane of the American company DOW.
- the tangential circulation speed of the clarified juice is adapted to the geometry of the micro-, ultra- or nanofiltration module used and may be of the order of 2 to 9 m / s, preferably 6 m / s.
- This circulation speed is regulated by the pump 10, it being specified that a portion of the filtered juice is brought back by a return line 11 a at the suction of said pump 10.
- a cation exchange resin in particular a strong cationic resin, in the Na + and / or K + form
- This column is provided, at its upper part, with a permeate inlet 16 connected to the outlet of the pump 14 and, at its lower part, with a conduit 17 for softened permeate outlet (content of Ca 2+ ions and / or Mg 2+ of the order of 150 to 700 ppm), the Ca 2+ and / or Mg 2+ ions present in the permeate brought to the head of the column (content of Ca 2+ and / or Mg 2+ ions of of the order of 7000 ppm) being retained by the resin during the progression of the permeate through the column by displacing the Na + and / or K + ions of this resin.
- the softened liquid extracted through line 17 then arrives in a reservoir 18 from where it is drawn off by a pump 19 to be brought into a concentration unit 20 which can be for example an evaporator such as a falling-stream evaporator.
- concentration unit 20 can be for example an evaporator such as a falling-stream evaporator.
- the syrup obtained from this unit 20 is then brought by a pump 21 into a crystallization unit 22 where it undergoes several successive crystallizations (three in the example illustrated in Figure 1) to deliver sugar to each stage of crystallization roux and molasses.
- the extraction yield of the sugars from the mass cooked is of the order of 65% at the level of the first crystallization stage, that the degree brown sugar obtained on this first stage is not more than 300 units ICUMSA and that this same sugar has a purity of 99.7%.
- the brown sugar produced on the first crystallization stage is subjected to a recasting operation in the reservoir 24, that is to say when it dissolves in water preferably hot at 80 ° C.
- the resulting syrup is then brought into a column of discoloration 25 filled with an adsorbent material such as animal black, charcoal active or a bleaching resin for example strong anionic resin in the form of chloride, such as IRA® 900 resin from Rohm and Haas).
- an adsorbent material such as animal black, charcoal active or a bleaching resin for example strong anionic resin in the form of chloride, such as IRA® 900 resin from Rohm and Haas.
- the discoloration is preferably carried out hot, for example at 80 ° C.
- the discoloration of the syrup can alternatively be carried out by ultrafiltration or nanofiltration tangential of said syrup.
- the syrup thus discolored is then treated in a crystallization unit 26 to deliver white sugar crystallized in 27 and a crystallization sewer in 28.
- the latter is preferably recycled by mixing it with the syrup from the concentration unit 20; he can also be used for the above-mentioned redesign operation.
- the brown sugar obtained in the second and third stages of crystallization of the crystallization unit 22 can, if desired, be remelted and then brought back to the top of this crystallization unit 22.
- the installation thus described can be completed by a circuit comprising a pump 29, the suction of which communicates by a conduit 30 with the base of the storage tank 23 and the discharge of which communicates by a conduit 31 with the upper part of the column of softening 15.
- This circuit will be implemented when it is desired to regenerate the resin filling the column 15, the molasses stored in the tank 23 serving as regeneration liquid due to its high content of Na + and / or K + ions and its low content of Ca 2+ and / or Mg 2+ ions.
- the installation represented by FIG. 2 is in all points identical to the installation represented by FIG. 1, except that the third crystallization stage of the crystallization unit 22 has been replaced by a chromatography column 32 operating at a temperature of the order of 80 ° C., where the molasses from the second crystallization stage of unit 22 is treated.
- This column is of the type comprising a fixed support constituted by a strong cationic resin, in the Na form + and / or K + , for example the resin DOWEX® C356 from the company DOW or the resin LES® 999301 from the company Rohm and Haas, the elution liquid being water brought into the upper part of the column by a conduit 33.
- This same column 32 is provided at its lower part with a conduit 34 for extracting a first liquid effluent depleted in sugars, enriched with Na and / or K salts and eluted first and with a conduit 35 extraction of a second liquid effluent e enriched in sugars, depleted in Na and / or K salts and eluted second.
- Said first effluent from line 34 is received in a storage tank 36. Due to its high content of Na + and / or K + ions, said first effluent can advantageously be used as regeneration liquid for the softening column 15 and this, in the same way as in the case of the installation of FIG. 1.
