- Advantages
- Phosphorus-free.
- Non-volatile at high temperatures and practically stable to hydrolysis.
- Dispersant to support the alkaline cleaning of evaporators in the cane sugar industry.
- KEBOSOL PM, as a dispersing additive to caustic alkaline solutions up to 30 °Bé, with the addition of 1 - 3 % sodium carbonate (Na2CO3), allows in favorable cases cleaning of evaporators without subsequent acidification.
- Has the ability to disperse coatings of calcium compounds and silicates and those with high proportions of organic degradation substances and partially detach them from the pipe wall. During this process, the calcium compounds contained in the coatings are partially converted into water-soluble complexes.
- Product Highlights
- With the dispersant KEBOSOL PM it is possible to use an alkaline method to clean evaporators that contain calcium oxalate deposits or mixed deposits of calcium oxalate and silicates.
- As a dispersing additive to alkaline and neutral solutions, in favorable cases it allows evaporators, preheaters and cooking apparatus to be cleaned without acid. Further areas of application are the dispersing of largely organic deposits and the stabilization of water hardness (Ca2+ and Mg2+) when hard water has to be used for dry cleaning.
- Has the ability to disperse calcium oxalate deposits and deposits with high levels of organic deposits and to partially detach them from the pipe wall. During this process, the calcium, magnesium, iron and other heavy metal compounds contained in the deposits are partially converted into water-soluble complexes.
- The detachment of deposits in soda solutions is also based on a substitution effect, so that when KEBOSOL PM is present, the active surfaces of the calcium carbonate formed are occupied by the dispersant and renewed agglomeration is prevented. If a tenside is used in addition to reducing the surface tension (eg KEBOSOL VD), this process is promoted.

- I&I Cleaning Applications
- Applications
- The dispersant KEBOSOL PM enables a successful alkaline cleaning of the evaporators scaled with calcium oxalate deposits or mixed scales of calcium oxalate and silicates.
- When adding KEBOSOL PM as dispersant to alkaline and neutral solutions, in favorable cases, evaporators, preheaters and pans can be cleaned without using acid.
- Other fields of application are the dispersion of mainly organic scales and the stabilization of water hardness (Ca2+ and Mg2+) if hard water has to be used for the chemical cleaning.
- KEBOSOL PM contains a combination of polymeric compounds with dispersing and sequestering properties in an optimum blend.
- The product is free from phosphorous, not volatile at high temperatures and practically resistant to hydrolysis.
- KEBOSOL PM has the ability of dispersing calcium oxalate scales as well as scales with a high content of organic substances and of removing them partly from the tube wall.
- During this process the compounds of calcium, magnesium, iron and other heavy metals contained in the scales are partly transformed into water soluble complexes.
- The removal of scales by sodium carbonate solutions is additionally based on a substitution effect so that in presence of KEBOSOL PM the active surfaces of the calcium carbonate being formed are covered with the dispersant and a new agglomeration is avoided.
- When in addition a surfactant (e.g.KEBOSOL VD) is used to reduce the surface tension, this process will be intensified.
- When using the dispersant KEBOSOL PM in combination with the activator KEBOSOL EVC for the alkaline cleaning, it is possible to eliminate scales of calcium sulfate and calcium oxalate or mixed scales containing calcium compounds and silicates from the evaporators.
- In most favorable cases the evaporators can be cleaned by adding KEBOSOL PM as dispersant and 1 - 3 % sodium carbonate (Na2CO3) to caustic alkaline solutions up to 30°Bé. An acidification will not be necessary.
- Areas of Application
Evaporator in cane sugar industry.
- Addition and Dosing
- In general the dosing rate of KEBOSOL PM to alkaline solutions amounts to 0.5 - 1.0 %.
- Systems treated with KEBOSOL PM have to be rinsed with water until they are free from residues before the sugar juice will flow again through these tubes.
- Remove / Protect Coatings
Calcium sulfate and calcium oxalate coverings or mixed coverings of calcium compounds and silicates.
- Material
In neutral and alkaline solutions

Storage & Handling
- Shelf Life
- 2 Years
- Storage
- In closed original packages KEBOSOL PM is storable for at least two years. The intensification of the color in case of a longer storage period does not have any influence on the quality and efficiency of the product. Protect from frost (enormous increase in the viscosity).
- Important Remark: Despite of increased viscosity at low temperatures the product is easy to handle; below 5°C the product may jellify, however, when the temperature rises it immediately liquefies again.
