  • Patent number: 10421914
    Abstract: A method comprising a combination and sequential methods to: a.-)Produce solid vacuum residue, b.-) Melt the solid vacuum residue, and c.-)Heat the melted Solid Vacuum residue. This invention applies to any single or mixture of hydrocarbons including one or more heavy crude oils, extra heavy crude oils, tar sands and/or bitumens, (named heavy feedstocks). The heavy feedstock is processed in the production field or a nearby location using atmospheric, vacuum distillation and a solid forming unit, to produce liquid distillates and a solid vacuum residue resulting from a deep cut point of the heavy vacuum gasoil. The Solid Vacuum Residue is melted and heated at the destination to be used as feedstocks in refineries deep conversion units to optimize operations and economics.This invention reduces the diluent imports at the heavy feedstocks production fields used for its production and/or its transportation.

  • Publication number: 20170253809
    Abstract: The “Solid Residue Separation” is a new way of manufacturing, processing and transporting hydrocarbons based on the qualities of the streams that allow optimization of the hydrocarbons supply chain by: (A) a new sequential line up of process units to produce liquid product(s) and a solid hydrocarbon product(s): “The Solid Residue Separation”; (B) Storage at the production site and/or transport to the final or intermediate destination solid vacuum residue via railcars, trucks, barges and/or ships to storage areas, terminal(s) and/or refineries; and (C) the processing and/or a blending of “Solid Residue Separation” by melting and heating them at the final destination(s) (i.e. storage areas, terminals and/or refineries) and feeding it directly to a vacuum distillation tower and/or to a deep conversion unit (i.e. delayed coker, fluidcoker, LC Fining, H-Oil, HDH, Uniflex, etc.) and/or direct them to blending.
