Production Facilities

Giriulla Factory

Adam Carbons operate two Vertical Kilns each with capacity 2000 MT & Two Rotary Kilns each with capacity 1800 MT of Activated Carbon per year and the both facility of Vertical & Rotary Technology making the plant to only one in the World able to manufacture Coconut Shell carbon with full range pore structure.

Adam Carbons’ strength lies in its ability to manufacture consistently high quality products with wide range of applications, Air Purification, Gold Recovery, Gas Purification, and Water Treatment. The pre and post processing systems are available to manufacture Special Products (Impregnated, Acid Wash) on request.

Production of activated carbon from coconut shell charcoal involves reaction between charcoal and steam at a temperature of around 900 C. the steam etches the rudimentary pore structure of the charcoal, improving it and making it more readily accessible for the absorption process. The method for doing this in the Adam Carbons production facility uses technology developed at the Guanghua Wood Working Factory in Beijing, where high quality activated carbon has been produced from a variety of raw materials for many years.

At Giriulla, the original two kilns consisting of a system of narrow vertical channels which allows steam to contact the charcoal at the required high temperature and simultaneously permit efficient heat recovery through combustion of gases produced by the steam/carbon reaction.

Prior to activation, coconut shell charcoal is crushed to the required size and loaded into the vertical channels. As the charcoal passes down the channels by gravity, it is first heated and then comes into contact with super-heated steam passing at right angles to it through specially shaped fire bricks. Residence time within the kiln is determined by the rate at which activated carbon is withdrawn from outlets at the bottom of the channels.
