Abstract:
The present invention relates to a process for the treatment of refinery purge streams, containing a hydrocarbon component in slurry phase having a boiling point higher than or equal to 140° C., characterized by the presence of quantities of asphaltenes higher than or equal to 5% by weight and characterized by the presence of a solid content higher than or equal to 5% by weight. The process provides that said purge be mixed with a suitable fluxing agent according to appropriate ratios and under certain conditions, forming a suspension with a content higher than or equal to 10% by weight of compounds having a boiling point TbP lower than or equal to 350° C. After mixing, the suspension is sent to a liquid/solid separation step which operates under suitable conditions, separating a solid phase containing a residual organic component and a solid component, called cake, and a liquid phase containing residual solids. The solid phase obtained is cooled to below 60° C., including the upper extreme, forming a granular solid which is stored and maintained at a temperature lower than or equal to 60° C.

Claim (Index 1):
A process for the treatment of refinery purge streams, the process comprising:\n a) withdrawing a refinery purge stream comprising a hydrocarbon component in slurry phase having a boiling point higher than or equal to 140\u00b0 C., characterized by the presence of quantities of asphaltenes higher than or equal to 5% by weight and characterized by the presence of solid contents greater than or equal to 5% by weight; b) mixing said purge, at a temperature higher than or equal to 100\u00b0 C., with a mixture of hydrocarbons or fluxing agent, having a total content of aromatic compounds ranging from 50% to 70% by weight, and an initial boiling point equal to or higher than the temperature at which the mixing is carried out, so as to form a suspension with a content higher than or equal to 10% by weight of compounds having a boiling point T bp  lower than or equal to 350\u00b0 C.; c) sending said suspension to a liquid-solid separation step, which operates at a temperature higher than or equal to 100\u00b0 C., separating a solid phase comprising a residual organic component and a solid component, or cake, and a liquid phase comprising residual solids; d) cooling the solid phase thus obtained to below 60\u00b0 C., comprising the upper extreme, and storing it, maintaining it at a temperature lower than or equal to 60\u00b0 C.; wherein a weight ratio between purge and fluxing agent ranges from 1:0.5 to 1:4; and an average residence time of the mixture during the mixing and before the liquid-solid separation is lower than or equal to 12 hours.
