Definitions
- the present invention relates to a process for refining a raw sugar, in particular brown sugar from the sugar cane industry.
- Known processes of this type include firstly a refining of the sugar raw which usually consists of washing the latter with the sewer of the last crystallization of high products, which dissolves the surface film of the most loaded with dyes. This gives a refined sugar and a refining sewer containing generally around 80-85% by weight of dry matter essentially consisting of sugar. This sewer is then subjected to several crystallizations in the bottom chain products to obtain brown sugar (which will be melted with refined sugar) and molasses. Taking into account that the concentrated refining sewer has a high content in dyes, the crystallization operations require very crystallization times and therefore make the crystallization systems unavailable for a long time. significant duration for other operations.
- refined sugar As for refined sugar (high products), it is subjected to an additional purification including operations of recasting, carbonation (treatment with calcium oxide or milk of lime and gas carbonic acid) or phosphating (treatment with calcium oxide or milk from lime and phosphoric acid), front filtration or decantation, discoloration and crystallization.
- this process is free from any preliminary operation tedious and expensive refining of raw sugar, which is made possible in any way completely unexpected, according to the invention, by the implementation of the technique of tangential microfiltration and / or tangential ultrafiltration, a well known technique, simple, flexible, high yield, fast, well controlled and with an operating cost much lower than that of the above-mentioned refining operation.
- the present invention overcomes a tedious and expensive operation by setting in a simple operation that consumes little time and energy.
- the method according to the invention can also comprise an operation flocculation using a flocculating agent, which can be carried out simultaneously with operation (b) or before or after this operation (b), the implementation of such a flocculation operation making it possible to very significantly reduce the quantities of reagents (calcium oxide or lime milk, carbon dioxide and acid phosphoric) to be used in the carbonation or phosphating operation.
- a flocculating agent which can be carried out simultaneously with operation (b) or before or after this operation (b)
- the implementation of such a flocculation operation making it possible to very significantly reduce the quantities of reagents (calcium oxide or lime milk, carbon dioxide and acid phosphoric) to be used in the carbonation or phosphating operation.
- the method comprises a flocculation operation and a phosphating operation, in which case calcium oxide (or milk of lime), phosphoric acid and the flocculating agent are put used in the phosphating and flocculation operations respectively at a rate of 200 to 900 ppm (expressed as CaO), 200-900 ppm (expressed as pure H 3 PO 4 ) and 200-900 ppm (expressed as active product) relative to the dry matter of raw sugar syrup.
- calcium oxide or milk of lime
- phosphoric acid and the flocculating agent are put used in the phosphating and flocculation operations respectively at a rate of 200 to 900 ppm (expressed as CaO), 200-900 ppm (expressed as pure H 3 PO 4 ) and 200-900 ppm (expressed as active product) relative to the dry matter of raw sugar syrup.
- the flocculating agent used in the flocculation operation can in particular be constituted by a cationic surfactant, in particular a compound quaternary ammonium tallow fatty acids, such as dioctadecyldimethylammonium, such as NORAMIUM® M2SH marketed by the French company CECA. They may also be derivatives of chitosan deacetylated poly-N-acetylglucosamine derived from chitin such as PROFLOC® SD 340 from the Norwegian company PROTAN BIOPOLYMER.
- the refining process according to the invention will be completed by an operation (d) for bleaching the sugar syrup resulting from microfiltration and / or ultrafiltration, and by an operation (e) of crystallization and / or demineralization of the sugar syrup resulting from the bleaching operation to obtain crystal sugar white in the case of crystallization and liquid sugar (syrup) in the case of demineralization.
- the raw sugar to be refined is brown sugar from a sugar cane candy, this brown sugar with a dry matter content (essentially sucrose) of the order of 97 to 99% by weight.
- aqueous medium such as a solution sweetened aqueous or preferably water.
- the aqueous medium is at a temperature sufficient for the recasting operation to be carried out at a temperature of the order of 50 to 90 ° C, preferably around 80 ° C.
- the redesign leads to a brown sugar syrup, the amount of medium aqueous use is preferably chosen so that said syrup has a content in dry matter of the order of 40 to 70% by weight.
- This redesign operation is carried out in a tank 1 provided at its upper part with an inlet 2 of brown sugar and a hot water supply 3. To obtain a homogeneous syrup, this tank is in additionally provided with stirring means 4.
- the brown sugar syrup resulting from this redesign operation which has usually a coloration of 2500-4500 ICUMSA units (international units) and a disorder of 3000-4000 ICUMSA units, is then subjected to an operation of phosphating in conjunction with a flocculation operation.
- the syrup is extracted at the base of the tank 1 by a conduit 5 connected to the suction of a pump circulation 6 whose delivery is extended by a conduit 7 leading to the part upper of a phosphating / flocculation tank 8.
- the syrup is reheated, for example by indirect heat exchange in a heat exchanger 9 disposed on the path of the syrup between the reservoir 1 and the reservoir 8. This exchanger is chosen to bring, if necessary, the syrup to a sufficient temperature so that within the tank 8 reigns a temperature of the order of 70 ° C.
- a flocculating agent is then introduced. Specifically, this the latter is brought to the upper part of the reservoir 8, from an agent reservoir 10 flocculant, comprising at its base an extraction duct 11 connected to the suction of a circulation pump 12 whose delivery is connected to a conduit 13 terminating to the reservoir 8.
- the reservoir 10 can be provided with heating means (not shown) such as an internal jacket in which a hot fluid circulates, for example water hot or steam, these heating means allowing, in the case where the flocculating agent is solid or pasty at room temperature, to bring it in the form liquid for pumping by pump 12.
- this agent flocculant consists of NORAMIUM® M2SH whose melting point is around of 60 ° C
- the heating means are designed to bring the latter to a temperature of the order of 60-65 ° C.
- the quantity of flocculating agent used is from 200 to 900 ppm of active product relative to the dry matter of the syrup Brown sugar ; for example in the case of NORAMIUM® M2SH this quantity will be preferably of the order of 500 ppm of active product relative to the dry matter of the syrup.
- lime milk is introduced into the reservoir 8 (at a concentration 200 g / l expressed as CaO) in an amount of the order of 300 ppm expressed as CaO relative to the dry matter of the syrup, then phosphoric acid (for example a 90% solution) until neutralization, approximately 250 ppm expressed as acid pure phosphoric and compared to the dry matter of the syrup.
- phosphoric acid for example a 90% solution
- the introduction of milk lime and phosphoric acid in tank 8 is carried out in the same way as for the flocculating agent, that is to say respectively from a reservoir 14 of milk lime and a reservoir 15 of phosphoric acid, via extraction pipes 16, 17, of circulation pumps 18, 19 and conduits 20, 21 connected to said pumps and leading to the reservoir 8.
- the reservoir 8 and provided with stirring means to achieve a violent mixing of its contents.
- the flocculating agent could, alternatively, be introduced into the tank 8 at the same time or after the milk of lime and phosphoric acid, however preference is given to the procedure described above. Under the effect of the flocculating agent, there is precipitation of part of the dyes and suspended solids. Much of the dyes and solids remaining suspension is removed by the phosphating operation, the phosphate of calcium formed by the reaction between milk of lime and precipitating phosphoric acid with occlusion of said dyes and suspended matter.
- the syrup having undergone the flocculation / phosphating is withdrawn from this reservoir 8 by a pump 22 discharging into a unit 23 of tangential microfiltration or tangential ultrafiltration. If necessary, the syrup thus withdrawn can be reheated so that the operation in this unit 23 takes place at approximately 80 ° C.
- the membrane used in unit 23 may have a cut-off threshold of 10 nm to 1 ⁇ m (preferably of the order of 0.1 ⁇ m), the syrup circulating with a tangential speed of the order of 1 to 8 m / s (preferably 4 to 6 m / s) and the permeate flow rate being of the order of 20 to 80 liters / hour.m 2 of membrane (preferably 35-50 liters / hour.m 2 of membrane).
- a membrane use can be made of organic polymer or ceramic membranes. Good results have been obtained with a zirconium oxide membrane on a ceramic support, manufactured by the French company TECH-SEP.
- the permeate from unit 23 (coloring of the order of 1000-2000 ICUMSA units and cloudiness less than 20 ICUMSA units) is routed through a conduit 24 in a storage tank 25, from which it is drawn off by a pump 26 to be brought at the head of a two-stage discoloration column 27, 28.
- These columns are packed dyestuff adsorbing material such as animal black, activated carbon or preferably a bleaching resin; it can be a strong anionic resin under chloride form (for example, IRA® 900 resin from Rohm and Haas).
- the operation of discoloration in this column is preferably carried out at 70-90 ° C, in particular at 80 ° C.
- the discolored syrup (coloring ⁇ 400 ICUMSA units) is brought into a tank 29.
- This discolored syrup can then be transformed into either crystal sugar or demineralized syrup.
- the syrup is brought by a pump 30 into an evaporator 31, for example a falling-stream evaporator, then the concentrated syrup is brought by a pump 32 into a crystallization unit 33 where it undergoes several successive crystallizations (three in the example illustrated in the figure) to deliver crystal sugar and a crystallization drain.
- the discolored syrup is brought, by a pump 34, from the reservoir 29 into a demineralization unit 35 which can for example consist of a column packed with a mixture of cationic resins in H + form and anionic in form OH - .
- This column in a mixed bed of resins can be replaced by two columns filled one with cationic resin in H + form and the other with anionic resin in OH - form. After the demineralization treatment, a syrup with a coloration ⁇ 20 ICUMSA units is obtained.
