KS Product

KS Product

The KS product is generally used to refine mineral oil as well as some chemical substances.

Various types of KS

KS (grade), based on all general and economical specifications, is divided into two main sub-grades:

1-Super grade, including, KS1, KS2, KS4, KS5, KS7, KS8, KS9

2-Special grade


Application of various types of KS

Refining oil (and refining some chemical substances) may be done in one, two or more phases with one or two various earth grades as follows:

1-KS1 and KS7 is used in refining recycled oil, gasoil.

2-KS8 and KS9 for solid paraffin and one stage of refining liquid paraffin and vazeline

3-KS2   and KS5 for liquid paraffin and vazeline

4-KS4 for soap production.

The special type: In order to comply with a consumer’s order, we can produce and customize the product based on our advice and guidelines. This is for the super grade. Hence special grades will be produced.


Chemical analysis:

Average Chemical analysis (based on the oxide of ingredients) of KS grades are as follows:

SIO          68.09

AL2O3    9.78

Fe2O3     0.84

Cao          1.15

Mgo         1.82

Na2O       0.33

K2O        0.71

P2O5       0.06

Mno         0.01

Tio2         0.08

S              0. 72

L . O. I   16.32


Mineralogic analysis:

This product mainly consists of argil minerals, the major part of which is Montmorilonite. The other minerals are silicate (Silos), “fold spats”as well as tiny amount of plaster and lime.

Effects of KS

Compared with the imported ones this type of earth enjoys the highest quality:

1-The highest strength in absorption of tiny suspended particles

2-The highest strength in bleaching (discolouring)

3-The highest strength in reduction and omitting P.A.H and sulfur compounds

4-The highest strength in absorption of heavy or poisonous metals

5-The colour not returning

6-High filtration speed

7-Minimum absorption of oil

 Optimized bleaching condition when using KS:

Operational conditions which must be consider for applying this Bentonite are different since the various oils refining process are different but in general you must observe the following factors according to the nature of your raw material:

1.    Temperature during the process of Bleaching

2.    Contact time duration of Bentonite with oil

3.    Mixed way of bleaching earth and oil together

4.    The amount of consumed acid during the entire filtering operation

5.    The amount of consumed lime during the entire filtering operation
