Abstract
The invention is directed to a process for agglomerating high-carbon dust, such as kish. The process comprises the steps of providing a supply of the high-carbon dust, applying a suifactant and water to the high-carbon dust, and applying a bonding agent to the high-carbon dust so that the high-carbon dust becomes agglomerated. The process provides a product having favorable characteristics. A substantially non-dusting high-carbon composition, for example, can be provided. The high-carbon composition comprises high-carbon dust, a surfactant, and a bonding agent in an amount by weight between about 1/20,000 and about 1/200 of the weight of the high-carbon dust. The high-carbon dust, surfactant, and bonding agent are agglomerated to form a clay-like material. A kish agglomerating system also is provided. The system comprises a kish storage container, a mixing tank, and a transport mechanism. The mixing tank has an agitator adapted to mix kish, surfactant and bonding agent so that the kish, surfactant and bonding agent become agglomerated. Also provided is a kish collection and treatment vessel. The vessel comprises a wall structure, a closure device, and a treatment applicator. The wa…
