Detailed description of the invention
Below based on embodiment, the present invention is described.But, following embodiment is an example of the present invention, and the present invention is not limited to embodiment disclosed below.
(refining plant of sucrose solution)
Fig. 1 is the schematic diagram of the process for purification of the sucrose solution illustrating present embodiment and refining plant.In the refining plant of Fig. 1, first tower 2 is single tower of the OH shape strong-base anion-exchange resin being filled with acrylic compounds, and the second tower 4 is that mixing is filled with the OH shape strong-base anion-exchange resin of phenylethylene and the mixed bed tower of H-shaped weak-acid cation-exchange resin.Further, when using this refining plant that sucrose solution is refined (desalination and decolouring), sucrose solution is passed into according to the order of first tower the 2, second tower 4.
Generally, containing pigment in sucrose solution, but the OH shape strong-base anion-exchange resin of acrylic compounds has the characteristic that low with the affinity of pigment and pigment absorption affinity is weak.On the other hand, the OH shape strong-base anion-exchange resin of phenylethylene has the characteristic that high and pigment the absorption affinity of the affinity with pigment is strong.Herein, the pigment contained by sucrose solution exists to absorption affinity low material high with the absorption affinity of ion exchange resin.
Therefore, the pigment that in the OH shape strong-base anion-exchange resin of acrylic compounds, primary attachment is high with the absorption affinity of ion exchange resin.The OH shape strong-base anion-exchange resin of acrylic compounds is originally weak with the absorption affinity of pigment, and the pigment being therefore adsorbed in this ion exchange resin easily can be departed from from ion exchange resin by regenerated liquid.Its result, will not make the OH shape strong-base anion-exchange resin of acrylic compounds deteriorate, it is possible to easily to make it regenerate and use.
As it has been described above, the pigment that in the first tower 2, primary attachment is high with the absorption affinity of ion exchange resin, therefore mainly low with the absorption affinity of the ion exchange resin pigment of residual in the sucrose solution after passing into the first tower 2.Therefore, the pigment that in the OH shape strong-base anion-exchange resin of the phenylethylene of the second tower 4, primary attachment is low with the absorption affinity of ion exchange resin.Therefore, even being adsorbed in the pigment of the OH shape strong-base anion-exchange resin of the phenylethylene high with the absorption affinity of pigment, it is also possible to be easily disengaged from by regenerated liquid.Its result, will not make the OH shape strong-base anion-exchange resin of phenylethylene deteriorate, it is possible to easily to make it regenerate and use.
As mentioned above, by filling the OH shape strong-base anion-exchange resin of acrylic compounds in the first tower 2, filling the OH shape strong-base anion-exchange resin of phenylethylene in the second tower 4, it is possible to carry out the decolouring of sucrose solution and desalination without making these ion exchange resin (especially the OH shape strong-base anion-exchange resin of phenylethylene) deteriorate because of decolouring (pigment absorption) with ability.Pigment is not high with the absorption affinity of the OH shape strong-base anion-exchange resin of phenylethylene, it is possible to easily departed from from the OH shape strong-base anion-exchange resin of phenylethylene by regenerated liquid, therefore, it is possible to reduce the consumption of regenerated liquid.
Think that the precursor structure of pigment and ion exchange resin adsorbs.The OH shape strong-base anion-exchange resin of phenylethylene has benzene structure in precursor structure, therefore high with the affinity of the pigment with similar structures (such as aromatic ring structure etc.), it is believed that strong with the absorption affinity of pigment.On the other hand, the OH shape strong-base anion-exchange resin of acrylic compounds do not have in precursor structure with pigment like structure, therefore low with the affinity of pigment, it is believed that weak with the absorption affinity of pigment.
As the OH shape strong-base anion-exchange resin of acrylic compounds filled in the first tower 2, for instance AMBERLITE (registered trade mark, same below) IRA958, IRA458 (DOWChemicalCompany system), PUROLITE (registered trade mark, same below) A860, A850 (PuroliteCorporation system) etc. can be listed.The quantitative change of the sucrose solution that in the OH shape strong-base anion-exchange resin of acrylic compounds, especially the ion exchange capacity of gel type resin is big, can process is many, is therefore advantageous for.As the OH shape strong-base anion-exchange resin of the acrylic compounds of gel-type, AMBERLITEIRA458 (DOWChemicalCompany system), PUROLITEA850 (PuroliteCorporation system) can be listed.The interior detail uniform pore diameter of the ion exchange resin of gel-type, and generally to have the form offer of the microballon of the transparency.On the other hand, there is the pore of different pore size in the ion exchange resin of porous type (micro-porous type, porous type) therein, has fine pore distribution, and generally provides with the form of lighttight opaque microballon.Therefore, by utilizing microscope to investigate the fine pore within ion exchange resin or the investigation light permeability for ion exchange resin, it is possible to be confirmed whether the ion exchange resin for gel-type.
OH shape strong-base anion-exchange resin as the phenylethylene being filled in the second tower 4, for instance AMBERLITEIRA900, IRA402, IRA402BL (DOWChemicalCompany system), PUROLITEA500S (PuroliteCorporation system), DIAIONSA10A, PA308 (Mitsubishi chemical Co., Ltd's system) etc. can be listed.
As the H-shaped weak-acid cation-exchange resin used in the second tower 4, for instance AMBERLITEIRC76, DOWEX (registered trade mark, same below) MAC-3 (DOWChemicalCompany system), PUROLITEC115E (PuroliteCorporation system), DIAIONWK10, WK11 (Mitsubishi chemical Co., Ltd's system) etc. can be listed.The precursor structure of H-shaped weak-acid cation-exchange resin is not particularly limited, for instance the H-shaped weak-acid cation-exchange resin of phenylethylene, acrylic compounds can be used.
Above-mentioned each ion exchange resin can use the ion exchange resin making OH shape (situation of anion exchange resin) and H-shaped (situation of cation exchange resin) by passing into regenerated liquid in advance before use.
(process for purification of sucrose solution)
The process for purification of the sucrose solution of present embodiment is as it is shown in figure 1, pass into sucrose solution according to the order of first tower the 2, second tower 4.That is, pass into sucrose solution along the direction shown in the arrow of Fig. 1, pass into sucrose solution from the top of the first tower 2 to bottom at first, from the bottom recovery sucrose solution of the first tower 2.Sucrose solution after recovery passes into from the top of the second tower 4 to bottom, from the bottom recovery sucrose solution of the second tower 4.
Now, the OH shape strong-base anion-exchange resin of the acrylic compounds filled in the first tower 2 can adsorb/remove anion (carbanion (CO3 2-), bicarbonate ion (HCO3 -), chloride ion (Cl-) etc.) and the high pigment of main and ion exchange resin absorption affinity.Sucrose solution after passing into the first tower 2 remains the anion (carbanion (CO not removed completely by the first tower 23 2-), bicarbonate ion (HCO3 -), chloride ion (Cl-) etc.), cation and the low pigment of main and ion exchange resin absorption affinity.By the sucrose solution after passing into the first tower 2 is passed into the second tower 4, the OH shape strong-base anion-exchange resin of the phenylethylene filled in the second tower 4 can adsorb/remove anion (carbanion (CO3 2-), bicarbonate ion (HCO3 -), chloride ion (Cl-) etc.) and the low pigment of main and ion exchange resin absorption affinity.The H-shaped weak-acid cation-exchange resin filled in second tower 4 can adsorb/remove cation (calcium ion (Ca2+), sodium ion (Na+) etc.).
Herein, the OH shape strong-base anion-exchange resin of acrylic compounds is originally just weak with the absorption affinity of pigment, and the pigment being therefore adsorbed in this ion exchange resin easily can be departed from from ion exchange resin by regenerated liquid.Its result, will not make the OH shape strong-base anion-exchange resin of acrylic compounds deteriorate, it is possible to easily to make it regenerate and use.The pigment that in the OH shape strong-base anion-exchange resin of the phenylethylene of the second tower 4, primary attachment is low with the absorption affinity of ion exchange resin, therefore, even being adsorbed in the pigment of the OH shape strong-base anion-exchange resin of the phenylethylene high with the absorption affinity of pigment, it is also possible to be easily disengaged from by regenerated liquid.Its result, will not make the OH shape strong-base anion-exchange resin of phenylethylene deteriorate, it is possible to easily to make it regenerate and use.
As mentioned above, in the process for purification of present embodiment, will not make the OH shape strong-base anion-exchange resin of the phenylethylene filled in the OH shape strong-base anion-exchange resin of acrylic compounds filled in the first tower 2 and the second tower 4 (in the middle of these, especially the OH shape strong-base anion-exchange resin of phenylethylene) deteriorate because of decolouring (pigment absorption), it is possible to refining (decolouring and the desalination) of sucrose solution it is repeatedly performed with ability.Pigment is not high with the absorption affinity of the OH shape strong-base anion-exchange resin of phenylethylene, it is possible to utilize regenerated liquid to make pigment easily depart from from the OH shape strong-base anion-exchange resin of phenylethylene, therefore, it is possible to reduce the consumption of regenerated liquid.
In the method for present embodiment, the sucrose solution that refine is not particularly limited, for instance the brown liquid (brownliquor) that cane suger raw material sugar of sening as an envoy to obtains can be enumerated through dissolving, carbonation, filter progress.
(renovation process of the refining plant of sucrose solution)
A～the D of Fig. 2 is the schematic diagram of the refining plant regeneration method illustrating and making Fig. 1.Refining by sucrose solution, hydroxide ion (OH-) depart from from the OH shape strong-base anion-exchange resin of the acrylic compounds in the first tower 2, adsorpting anion (carbanion (CO3 2-), bicarbonate ion (HCO3 -), chloride ion (Cl-) etc.), and adsorpting pigment.Hydrion (H+) and hydroxide ion (OH-) depart from from the OH shape strong-base anion-exchange resin of the H-shaped weak-acid cation-exchange resin in the second tower 4 and phenylethylene respectively, Liquidity limit (Ca ion (Ca2+), Na ion (Na+) etc.), anion (carbanion (CO3 2-), bicarbonate ion (HCO3 -), chloride ion (Cl-) etc.) and pigment.That is, sucrose solution refining after, the OH shape strong-base anion-exchange resin in the first tower 2 becomes such as Cl--strong-base anion-exchange resin, CO3 2--strong-base anion-exchange resin, HCO3 --strong-base anion-exchange resin.After refining, the H-shaped weak-acid cation-exchange resin in the second tower 4 becomes such as Ca2+-weak-acid cation-exchange resin, Na+-weak-acid cation-exchange resin, OH shape strong-base anion-exchange resin becomes such as CO3 2--strong-base anion-exchange resin, HCO3 --strong-base anion-exchange resin, Cl--strong-base anion-exchange resin.Further, precursor structure of OH shape strong-base anion-exchange resin in the first tower 2 and the second tower 4 etc. is adsorbed with pigment.
In the renovation process of present embodiment, first as shown in the A of Fig. 2, in the second tower 4, bottom it, pass into water (H to top2O).Thus, strong-base anion-exchange resin and weak-acid cation-exchange resin in the second tower 4 flow, separated due to the difference of specific gravity of these ion exchange resin (backwash partition method).In present embodiment, by separating, in the second tower 4, strong-base anion-exchange resin 4a is configured in top, and weak-acid cation-exchange resin 4b is configured in bottom.
Then, as shown in the B of Fig. 2, pass into the sodium hydrate aqueous solution of the first regenerated liquid as OH shape strong-base anion-exchange resin from the top of the second tower 4 to the second tower 4, pass into water from the bottom of the second tower 4 simultaneously.By making this water and the first regenerated liquid convection current, it is possible to prevent the first regenerated liquid from arriving the weak-acid cation-exchange resin 4b to the bottom being split in the second tower 4.Further, the interceptor(-ter) being positioned at by the strong-base anion-exchange resin of phenylethylene separated from one another and the boundary portion of weak-acid cation-exchange resin is utilized to reclaim the first regenerated liquid.So, by reclaiming the first regenerated liquid with interceptor(-ter), it is possible to prevent the first regenerated liquid from arriving and make weak-acid cation-exchange resin deteriorate to the weak-acid cation-exchange resin of the bottom being split in the second tower 4.By passing into the first regenerated liquid in the second tower 4, make such as carbanion (CO3 2-), bicarbonate ion (HCO3 -), chloride ion (Cl-) depart from from the strong-base anion-exchange resin of the phenylethylene in the second tower 4, instead adsorb hydroxide ion (OH-), form the OH shape strong-base anion-exchange resin of phenylethylene.
Then, the first regenerated liquid after passing in the second tower 4 and the first regenerated liquid (sodium hydrate aqueous solution) added are passed into from the top of the first tower 2 to bottom.It is not particularly limited by the order that the first regenerated liquid after passing in the second tower 4 and the first regenerated liquid of adding pass in the first tower 2, preferably the first regenerated liquid after passing in the second tower 4 is passed in the first tower 2, then the first additional regenerated liquid is passed in the first tower 2.According to circumstances, it is also possible in the first tower 2, do not pass into the first additional regenerated liquid.Thus, the strong-base anion-exchange resin of the acrylic compounds in the first tower 2 is regenerated.That is, such as carbanion (CO is made3 2-), bicarbonate ion (HCO3 -), chloride ion (Cl-) depart from from the strong-base anion-exchange resin of acrylic compounds, instead adsorb hydroxide ion (OH-), form the OH shape strong-base anion-exchange resin of acrylic compounds.
Before above-mentioned regeneration, the pigment that the strong-base anion-exchange resin primary attachment of the acrylic compounds of the first tower 2 is high with the absorption affinity of ion exchange resin, the pigment that the strong-base anion-exchange resin primary attachment of the phenylethylene of the second tower 4 is low with the absorption affinity of ion exchange resin.The strong-base anion-exchange resin of acrylic compounds is originally weak with the absorption affinity of pigment, and the pigment being therefore adsorbed in this ion exchange resin can be easily disengaged from by the first regenerated liquid in the operation of the B of Fig. 2.Its result, will not make the strong-base anion-exchange resin of acrylic compounds deteriorate, it is possible to easily to make it regenerate.The strong-base anion-exchange resin being adsorbed in phenylethylene is the pigment low with the absorption affinity of ion exchange resin, therefore can be easily disengaged from by the first regenerated liquid in the operation of the B of Fig. 2.Therefore, it is possible to reduce the consumption of the first regenerated liquid used in the operation of the B of Fig. 2.
In present embodiment, use sodium hydrate aqueous solution as the first regenerated liquid, as long as but the first regenerated liquid aqueous slkali be just not particularly limited, it may be preferred to for sodium hydrate aqueous solution or potassium hydroxide aqueous solution, it is possible to be more preferably sodium hydrate aqueous solution.As long as the naoh concentration in sodium hydrate aqueous solution will not make ion exchange resin, deterioration is just not particularly limited, it is preferred to 0.05～3.0 equivalent, be more preferably 0.5～2.0 equivalent.
Then, as shown in the C of Fig. 2, pass into the hydrochloride aqueous solution of the second regenerated liquid as H-shaped weak-acid cation-exchange resin from the bottom of the second tower 4 to the second tower 4, in the second tower 4, pass into water from the top of the second tower 4.Then, from interceptor(-ter) Recycling of waste liquid (the second regenerated liquid and water).So by reclaiming the second regenerated liquid with interceptor(-ter), the second regenerated liquid arrives the OH shape strong-base anion-exchange resin of the phenylethylene to the top being split in the second tower 4, it is possible to prevent hydroxide ion (OH-) depart from and adsorbing chlorinated thing ion (Cl from the OH shape strong-base anion-exchange resin of phenylethylene-), thus becoming Cl--strong-base anion-exchange resin.By the second regenerated liquid, cation (Ca ion (Ca2+), Na ion (Na+) etc.) depart from from the weak-acid cation-exchange resin in the second tower 4 and regenerate, become H-shaped weak-acid cation-exchange resin.
In the present embodiment, use hydrochloride aqueous solution as the second regenerated liquid, as long as the second regenerated liquid acid solution is just not particularly limited.When using hydrochloride aqueous solution, as long as the hydrogen cloride concentration in solution will not make ion exchange resin, deterioration is just not particularly limited, it is preferred to 0.05～2.0 equivalent, be more preferably 0.1～1.0 equivalent.
Then, as shown in the D of Fig. 2, from the bottom of the second tower 4 to the second tower 4, circulation compression air, makes the OH shape strong-base anion-exchange resin of the phenylethylene of separated configuration in the second tower 4 flow with H-shaped weak-acid cation-exchange resin and mix.Thus, in the second tower 4 after terminating compressed-air actuated inflow, mixing is filled with OH shape strong-base anion-exchange resin and H-shaped weak-acid cation-exchange resin, and the second tower 4 becomes mixed bed.
After each tower passes into each regenerated liquid, Xiang Geta passes into water, drives out of and make it to discharge outside tower the regenerated liquid of residual in each tower.Water can also be passed at the rear of the operation of the D of Fig. 2 to each tower, clean the ion exchange resin in tower.
