Verwendung eines aus quecksilberhaltigem Ölschlamm aus der Erdölförderung erhaltenen Produktes zur Herstellung von keramischen Erzeugnissen

摘要

This is an original method disposing of crude oil production sludges, including contaminants, by putting them to good use. The principal original feature is exploitation of the waste as a secondary raw material in the manufacture of ceramic products, for example bricks or tiles. Preferably, the waste is also used to make melt granules. Firstly, coarse objects are separated. The remaining material is screened or washed, separating out the coarse materials. The contaminants are enriched into a fine granular fraction (clay or silt). This is dried to over 90% by weight of dry matter content. Low temperature coking follows, freeing the dried matter of oil and mercury.
