Activated Fullers Earth

ICMC Products

ICMC Bleaching Earth (Activated Fuller Earth) found most suitable for bleaching and delecolourising soyabean oils, Repressed oils, coconut Oils, Mustard Oils, cottonseed Oils Groundnuts Oils, Sesame oil, Safflower oil, Rice bran oil, Palm oil etc. for the purpose of Hydrogenated oil or refined oil.

ICMC Bleaching earth is the most important agent for Bleaching and Decolourising de-gummed and Alkali Refined oils by adsorption. In the process of bleaching ICMC Bleaching Earth is used alone with activated carbon to remove colour, gums, resins and other impurities present in the oily adsorption due to their High Surface Activities, while having no effect on the composition of the oil so treated.

APPLICATIONS     

 

The Highly sportive qualities of ICMC attapulgite make it ideal for a wide range of applications. The following are but the few of the many ways ICMC attapulgite has been effectively applied.

Polymerising pinen tupentine and other terpene liquids. It is used for removing gum forming constitutes from gasoline blending stock.          

     

Oil Decolourising and Refining     

ICMC attapulgite is used for the decolourising, stabilizing, neutralising, clarifying and decolourising sizes of solvents, mineral oils, fats and waxes. For these purposes both percolationand contact methods are employed.  

     

Cleaning Oily Workshop Floor      

ICMC Attapulgite Granulars are available in various grades for cleaning oily workshop Floor.  

     

Pesticides Carriers and Diluents  

ICMC Attapulgite in a granulars or powder from is used with many Pesticides formulations.    

 

Reclaiming Reclaiming

ICMC attapulgite is an excellent adsorbent for the reclamation or regeneration of used transformer oils, fats and waxes, dry cleaning solvents.         

     

Reclamation may involve a complete reprocessing of the used materials reforming it to its original state or simply a clean up involving the removal of water, acids, or solid contaminates. These operation may be of batch types or continuous type. A simple filtration through ICMC attapulgite can economically remove certain contaminants in some cases.           

     

Re-refining of Engine, Lubricating Oils

AMGEEN is a specially processed grade of Attapuligite clay (hydrous magnesium aluminum silicate). Its unique physical properties make it most effective as a bleaching neutralizing and decolourising agent in the re-refining of engine and lubricating oils by contact methods.       

     

Filtration of Special Product         

ICMC attapulgite is used for decoloursing neutralising and stabilizing such materials as resins tall oils, cocoa butter animal oils, fish oils etc.

                  

PROCESS 

Percolation Methods

 

The material to be processed is filtered through column of granular attapulgite clay which has been heat activated usually between 300oc to 600oc the rate of percolation , temperature of operation and optimum temperature of activation of attapulgite are variable which should be determined experimentally for a specific application.

     

Contact Methods  

 

The material to be treated is mixed with Amgeen attapulgite and slurry stirred for period of five to thirty minutes at elevated temperature under vacuum. The treated product is recovered by filtering through a plate and frame or continuos type of filter for optimum result , the amount of attapulgite clay used the temperature and the time of treatment should be determined by experiment.
