A NOVEL METHOD OF PURIFICATION OF THE SUGAR CONDENSATE
3. PREAMBLE TO THE DESCRIPTION
Field of Invention
The present invention relates to a novel method of purification of the sugar condensate by removal of the organic matters and the dissolved impurities in it.
Background of the Invention & the Related Art
Currently there are a few methods used for purification of the sugar condensate to remove or eliminate the organic matters and the dissolved impurities in the said sugar condensate.
Currently, some of the specialty membranes of reverse osmosis are being used for removal of the organics from sugar condensate. However, the low molecular weight volatile organic compound passes through the membrane. Hence, the removal is not upto the acceptable satisfactory level. The organic removal is upto 50 level only. The other point is that, the condensate being treated at high temperature, this limits the use of different types of reverse osmosis membranes. Hence, there is no 100% full proof as well as an economical methods which can give the organics removal upto 90%.
4. DESCRIPTION OF THE INVENTION
In the invention under consideration, to process the sugar condensate in the most purified form basically four units viz. the steam-stripping unit, the activated carbon filter, the cation resin unit and the anion resin unit are used.

The sugar condensate is initially passed through steam-stripping unit under the hot condition. With this the volatile organic compounds are eliminated from the condensate. Further, the sugar condensate duly passed through the steam-stripping
unit under the hot conditions is collected and stored in the condensate storage tank.
Then, the said sugar condensate stored in the condensate storage tank with the help of the feed pump is passed through the filter. The filter used in the process under consideration is an activated carbon filter. These activated carbon filters are generally and extensively used in the ware treatment plants for the removal of the organic matters from the water and to free chlorine and for odour. The activated carbon filter to be used in the method under consideration has be with the carbon of the such a quality that, the said carbon shall be in a position to remove all the volatile organic compounds present in the sugar condensate. Keeping this in mind the carbon used in the process under consideration is of a high quality with high surface area and porosity. The carbon used in the process under consideration is of Iodine Number about 1000\ (The Iodine Number indicates the quality of the carbon). The sugar condensate is to pass through the activated carbon filter either under the hot conditions or at the ambient temperature. By passing through the activated carbon filter the volatile organics present in the sugar condensate are removed.
After the removal of the volatile organics present in the sugar condensate by passing the same through the activated carbon filter, the said sugar condensate passed through the cation resin unit. In the cation resin unit there is cation resin. The cation resin is generally & widely used in all the water treatment plants for removal of the cations from the water to be treated. The said cation resin may operate over a wide range of varying temperatures upto 120 celcious. The cation resin is normally regenerated with dilute acids viz. hydrochloric acid, sulfuric acid

and nitric acid. In the process under consideration the cation resin used is the strong acid cation resin being styrene-DVB cross-linked type.
When the sugar condensate passed through the cation resin unit, the cation resin in the said unit, exchanges cations from the sugar condensate such as calcium, magnesium and sodium against hydrogen. The above reaction is shown with the following equation:
CaC12 + R. H > R- Ca + HC1
Herein, R is referred as Resin Matrix.
Thus, with passing through the cation resin unit the cations present in the sugar condensate are removed.
Further to the removal of the cations present in the sugar condensate on passing the same through the cation resin unit, the said sugar condensate is made to pass through the anion resin unit. The main function of the anion resin is to absorb the all the acids from the sugar condensate formed in the said sugar condensate. The second function of the anion resin is to convert the sugar condensate into the dematerialized sugar condensate.
The anion resin is also useful in removal of the organics from the sugar condensate alongwith the other anions.
In the process under consideration, the poly styrene-DVB cross-linked polymer anion exchange resin is used. The said anion resin works over a large pH range and after exhaustion regenerated by dilutes strong alkali.
-4-

The resin used as anion resin in removal of the organic removal is called as Macroporous type, the said resin has sufficient surface area to absorb the organics present in the sugar condensate.
The above reaction is shown with the following equation:
R . OH + HC1 > R . CI +H .OH
Thus the process of the removal or the elimination of most of the organic matters and the dissolved impurities present in the sugar condensate by passing through the said sugar condensate through steam stripping unit, the filter, the cation resin unit and the anion resin unit as discussed earlier.
Description of the Figure:
The figure describes the schematic flow diagram for a novel method of purification of the sugar condensate by removal of the organic matters and the dissolved impurities in it.
In the novel method of purification of the sugar condensate by removal of the
organic matters and the dissolved impurities in it, the sugar condensate (3) is introduced in the steam-stripping unit (1) through the sugar condensate inlet (2).
Further, the sugar condensate (3) is treated by the hot steam (4) being introduced through the steam inlet (5). Thus the sugar condensate (3) is passed through the hot conditions.
Further, the duly treated sugar condensate (3) in the steam-stripping unit (1) under hot conditions is allowed to flow out of the steam-stripping unit (1) through the deaerator outlet (6). Subsequently, the treated sugar condensate (3) is collected and stored in the condensate storage tank (7).

Next, the treated sugar condensate (8) stored in the condensate storage tank (7) is released through the feed pump (9) to the filter (10), which is an activated carbon filter (10). By passing the sugar condensate (11) to an activated carbon filter (10) all the volatile organic compounds present in the sugar condensate (11) are removed. The activated carbon filter (10) to be used in the method under consideration is with the carbon (12) of such a quality that, the said carbon (12) shall be in a position to remove all the volatile organic compounds present in the sugar condensate (11). Keeping this in mind the carbon (12) used in the process under consideration is of a high quality with high surface area and porosity. The carbon (12) used in the process under consideration is of Iodine Number about 1000V The sugar condensate (11) is to pass through the activated carbon filter (11) either under the hot conditions or at the ambient temperature.
Further to this, on the removal of the volatile organics present in the sugar condensate (11) by passing the same through the activated carbon filter (10), the said sugar condensate (11) is passed through the cation resin unit (13). In the cation resin unit there is cation resin (14). The cation resin (14) is generally & widely used for removal of the cations from the substance to be treated. The said cation resin (14) may operate over a wide range of varying temperatures upto 120° celcious. The cation resin (14) is normally regenerated with dilute acids viz. hydrochloric acid, sulfuric acid and nitric acid. In the process under consideration the cation resin (14) used is the strong acid cation resin being styrene-DVB cross-linked type.
When the sugar condensate (15) is passed through the cation resin unit (13), the cation resin (14) in the said unit (13), exchanges cations from the sugar condensate (15) such as calcium, magnesium and sodium against hydrogen. The above reaction is shown with the following equation:
-6-

CaC12 + R. H > R-Ca + HC1
Herein, R is referred as Resin Matrix.
Thus, with passing through the cation resin unit (13) the cations present in the sugar condensate (15) are removed.
Further to the removal of the cations present in the sugar condensate (15) on passing the same through the cation resin unit (13), the said sugar condensate (15) is made to pass through the anion resin unit (16). The main function of the anion resin (17) present in the anion resin unit (16) is to absorb the all the acids from the sugar condensate (18) formed in the said sugar condensate (18). The anion resin (17) also converts the sugar condensate (18) into the demineralized sugar condensate (19). The anion resin (17) is also useful in removal of the organics from the sugar condensate (18) alongwith the other anions.
In the process under consideration, the poly styrene-DVB cross-linked polymer anion exchange resin (17) is used. The said anion resin (17) works over a large pH range and after exhaustion regenerated by dilutes strong alkali.
The resin (17) used as anion resin (17) in removal of the organic removal is called as Macroporous type, the said resin (17) has sufficient surface area to absorb the organics present in the sugar condensate.
The above reaction is shown with the following equation:
R . OH + HC1 > R . CI +H .OH
At the end of the whole the above process so described above, the treated sugar condensate (19) is passed to and stored in the sugar treated condensate tank (20).

Thus the process of the removal or the elimination of most of the organic matters and the dissolved impurities present in the sugar condensate by passing through the said sugar condensate through steam stripping unit, the filter, the cation resin
unit and the anion resin unit as discussed earlier.
