Abstract

See full text

The present invention relates to reaction equipment for the treatment of organic and/or inorganic waste of refineries or petrochemical plants comprising: •—a drying and pyrolysis device (4) which rotates around its longitudinal, tilted rotation axis (A), •—a gasification device (6) which rotates around its longitudinal, horizontal rotation axis (B), •—a combustion device (14) comprising a burner (13) having a longitudinal horizontal axis (C), •—at least one settling chamber (15) for the collection of intermediate solid residues and the accumulation of intermediate gaseous reaction products, •—at least one outlet duct of the gaseous end-products (16), at least one outlet duct of the solid end-products (7), and at least one inlet duct of the feedstock (2) •—said combustion device (14), drying and pyrolysis device (4), gasification device (6) are physically separated and positioned on three different levels, •—the longitudinal rotation axis (A) of the drying and pyrolysis device (4) is tilted with respect to both the longitudinal rotation axis (B) of the gasification device (6) and also with respect to the longitudinal axis (C) of the combustion device (14), •—the longitudinal rotation axis (B) of the gasification device (6) is parallel to the longitudinal axis (C) of the combustion device (14), •—the combustion device (14) is in fluid communication with the drying and pyrolysis device (4), •—the drying and pyrolysis device (4) comprises, in its interior, a first indirect heat exchange device (3) in which the combustion fumes coming from the combustion device (14) flow, •—at least one settling chamber (15) in fluid communication with said drying and pyrolysis device (4) and with said gasification device (6) and with said combustion device (14), •—conveying means (5) are positioned in the settling chamber (15) and put the drying and pyrolysis device (4) in fluid communication with the gasification device, •—it comprises a second heat exchange device (12) in fluid communication with the first indirect heat exchange device (3) and the combustion device (14), •—it comprises means for the suction of the intermediate gaseous reaction products, said means being positioned in the settling chamber (15).
