A multi-diameter elastic sealing module for pigs, which operates in pipes having diameter changes, by being sent through the inside of a flexible or rigid pipe to move or draw various fittings and remove internal incrustations from the pipe, impelled by a fluid which flows inside said pipe. The sealing module comprises a sealing/impelling element (), a flexible core () covered by the sealing/impelling element (), a first clamping element (), a second clamping element (), a first fastening element () and a second fastening element ().

A systemis described for the treatment of multiphase residues having unlimited content of water, oil and solids to obtain hydrocarbons and other products, said system comprising multiphase residue feed system, inert gas systemand reduced pressure system, tubular reactorprovided with three heating zones Z-, Z-and Z-with a temperature gradient and transportation helicoidto displace the residue mass throughout the reaction zones, the hydrocarbon products and water being collected in a systemof condensersandlinked to a systemof bubbling vesselsand, reactorbeing operated in the sealed mode and being provided with a multiphase residue inletand exitof solid product. The solid product is collected in a systemcomprising upper valveand lower valve, and intermediate siloand then directed to post-treatment systemfor activation aiming at industrial utilization. The process using the systemof the invention is also described. Multiphase organic residues, petroleum residues, pure or in admixture in any amount, from chemical and pharmaceutical industries, paper and pulp industry, and mining industries can be processed in the inventive system. Besides, it is possible to recover phenols from foundry sands in the system and process described.
