Abstract
Sorbitol in this design is obtained through a catalytic hydrogenation process of a solution between dextrose and hydrogen gas with the aid of a Raney nickel catalyst. Dextrose is stored in a dextrose storage warehouse (F-111) and transported to hopper I (F-113) with the aid of a bucket elevator (J-112). The dextrose is then dissolved in water in the dissolution tank (M-110) with the help of a screw conveyor (J-114) to produce a 50% dextrose solution. This 50% dextrose solution is then fed into the mixer (M-120) to be mixed with the Raney nickel catalyst first. The Raney nickel catalyst is stored in the catalyst storage warehouse (F-121). The catalyst is transported with the help of a bucket elevator (J-122) to the hopper (F-123) and screw conveyor (J-124) to the mixer (M-120). The dextrose and nickel solution is then flowed to the heater (E-212) to raise its temperature to 1600C. Next, the dextrose and nickel solution is flowed to the catalytic hydrogenation reactor (R-210). This process is carried out at a temperature of 1600C and 100 atm. The sorbitol is then separated by a separator (H-310). The hydrogen that does not react is separated by a separator and then recycled for the next catalytic hydrogenation process. After the separator, the sorbitol is fed into a cooler (E-321) to be cooled to 40°C, which is then filtered by an LSM filter (H-320). The successfully separated catalyst will be recycled for the next hydrogenation process. Sorbitol is then purified with cation (D-410) and anion exchangers (D-420) to remove Al impurities contained in the Raney nickel catalyst. Next, the sorbitol is fed into the carbonation tank (D-430) for the purification process. The adsorption process is aided by activated carbon to absorb the color produced from the previous process, resulting in clearer sorbitol. The purified (50%) dilute sorbitol solution is fed into the The purified dilute sorbitol solution (50%) is fed into the evaporator (V-440) at a temperature of approximately 100°C for concentration. Sorbitol with a concentration of 85% is produced. The sorbitol is then cooled using a cooler (E-452) and sent to the product storage tank (F-450).
