摘要： The present invention relates to a method for the physical separation of solids and asphaltenes with a conversion degree higher than or equal to 90%, present in refinery purge streams. Said method provides for heating a refinery purge stream to a temperature higher than or equal to 185°C and not exceeding 220°C and, subsequently, subjecting said heated purge to sedimentation by progressively lowering the temperature in a controlled manner to a minimum temperature of 100°C, without stirring the purge, so as to form a light phase and a heavy phase defined in relation to the density.

摘要： The present invention relates to a process for the selective recovery of transition metals from an organic stream containing transition metals. The organic stream and possibly a first extractor if solid, are melted up to the liquid state. The extractor consists of an ionic liquid or a mixture of two or more ionic liquids, wherein said ionic liquid contains an ammonium salt as cation and as anion an anion with chelating properties. A melted organic stream and a first extractor, optionally melted, are fed to a first liquid-liquid extraction unit working at a temperature of at least 150 °C where the liquid-liquid extraction is carried out obtaining a liquid mixture containing an ionic liquid, or a mixture of two or more ionic liquids, and metals. After extraction, the liquid mixture is cooled at a temperature between 0 °C and 70 °C and becomes biphasic; then the cooled mixture is sent to a first separation unit, to separate a liquid phase that contains ionic liquids and metals, and a metal-depleted solid phase. After the first separation, the separated metal-depleted solid phase is optionally sent to a washing unit to which a solvent is fed, so as to eliminate the residual ionic liquid by transferring it into the solvent and obtaining a metal-depleted solid phase. Then the separate liquid phase containing ionic liquids and metals is sent into a liquid-liquid precipitation and separation unit, adding a counter-solvent, thereby obtaining a solid phase containing the metals and a liquid stream containing counter-solvent and ionic liquids.

摘要： The present invention relates to a process for the hydroconversion of mixtures of polymers or plastics which comprises the pre-treatment of the mixtures through methods selected from mechanical methods, chemical methods, thermal methods, or combinations thereof forming a pre-treated charge. The pre-treated charge is mixed with a hydrocarbon vacuum residue, optionally pre-heated, to form a reactant mixture. The reactant mixture is fed to a hydroconversion section in slurry phase, together with a catalyst precursor containing Molybdenum, and a stream containing hydrogen, forming a reaction effluent. The effluent is separated into at least one high-pressure and high-temperature separator in a vapour phase and a slurry phase. The separate vapour phase is sent to a gas treatment section with the function of separating a liquid fraction from the gas containing hydrogen and hydrocarbon gases having from 1 to 4 carbon atoms; said liquid fraction comprising naphtha, atmospheric gas oil (AGO), vacuum gas oil (VGO). The slurry phase is then sent to a separation section that has the function of separating the fractions of the Vacuum Gas Oil (VGO), Heavy Vacuum Gas Oil (HVGO), Light Vacuum Gas Oil (LVGO), Atmospheric Gas Oil (AGO), from a stream of heavy organic products which contains asphaltenes, unconverted charge, catalyst and solid formed during the hydroconversion reaction. This stream of heavy organic products is partly recirculated to the hydroconversion section and partly forms a purge stream.

摘要： The present invention relates to a process for the hydroconversion of heavy oil products which comprises the following steps in which heavy oil products and hydrogen are supplied to a slurry hydroconversion section which contains a molybdenum-based catalyst. The reaction effluent is separated into a vapour phase and a slurry phase. The slurry phase is sent to a separation section which has the function of separating the Vacuum Gas Oil (VGO), Heavy Vacuum Gas Oil (HVGO), Light Vacuum Gas Oil (LVGO), Atmospheric Gas Oil (AGO) fractions, from a stream of heavy organic products which contains asphaltenes, unconverted feed, catalyst and solid formed during the hydroconversion reaction. This stream is partly sent to the reaction section and partly forms a purge stream. The purge stream is heated and made fluid at temperatures comprised between 185°C and 220°C, and subsequently subjected to a static settling unit up to a minimum temperature of 100°C. From the settling unit two new products defined as clarified component and cake are obtained. The clarified component is recycled to the hydroconversion reaction section.
