A thermic lithosynthesis process for disposal of liquid and solid industrial wastes

摘要

A thermic lithosynthesis process for disposal of liquid and solid industrial wastes in the production of inert clay agglomerates, consisting of a cold working step comprising:milling of clay into granules, mixing said clay granulates with liquid and/or industrial wastes, such as oil raffinery sludges, organic substances, exhausted and emulsioned oils etc., laminating and maturing said mixture to obtain a homogeneous paste and a warm working step comprising: heating said paste by burners with conventional fuels to evaporate the water content and to obtain a granular material, heating said granular material by burners fed with conventional fuels and/or by exhausted and/or emulsioned oils to expand the inner portion of granules and obtain a glassy outer layer thereof, cooling said expanded granules to attain clay agglomerates adapted for manufacturing cements and concretes.
