The Challenge
Reduction of high ash content, colour and conductivity in Liquid Glucose. Due to high ash and colour content the product could not meet the requirements of the end users.
The Solutions
To reduce ash content, colour and conductivity liquid glucose was passed though columns of INDION 225H & INDION 860 S.
Result
After passing liquid glucose through ion exchange columns containing INDION 225 H and INDION 860 S, the treated liquid glucose exactly meet the customer’s requirement with respect to reduction in ash content
Details of existing Liquid Glucose deashing plant:
| INDION 225 H | INDION 860 S | |
|---|---|---|
| Resin qty, liters | 1600 | 2200 |
| Regeneration level, kg/m³ | 75 | 68 |
| Service flow, m³/h | 2 | 2 |
| OBR, m³ | 35 | 35 |
| Parameter | Before Treatment | After Treatment |
|---|---|---|
| Ash Content, w/w | 0.8 % | <0.2 % |
Pre-treatment
(a) SAC resins INDION 225 H Rinse with approx 20 BV of water and exhaust with 2 BV of 4% NaOH or 10% NaCl solution followed by rinse, regenerate with 2 BV of HCl or H2SO4 followed by rinse. Repeat the above steps one more time followed by regeneration and rinse
(b) WBA INDION 860 S resins Exhaust the resin with 2 BV of 4% HCl or H2SO4. Rinse. Regenerate with 2 BV of NaOH. Rinse. Repeat the above steps one more time.
