  • Publication number: 20190023994
    Abstract: A process for the removal of mercury comprising reacting a sulfide source with HgS solids to increase the size and sedimentation rate of the submicron mercury for removal by filtration or other mechanical processes is described herein. An embodiment of the invention is the use of monothiols to react with mercury to form dissolved mercury, wherein silica with immobilized thiol groups is added to the dissolved mercury, allowing for removal with a coarse filter.

  • Patent number: 9562199
    Abstract: This invention relates to systems and methods for catalytic steam cracking of non-asphaltene containing heavy hydrocarbon fractions. The method enables upgrading heavy hydrocarbons to hydrocarbons capable of being transported through pipelines and/or a pretreated step before further treatment in an upgrading refinery, including the steps of separating the heavy hydrocarbon mixture into a light fraction, a full gasoil fraction and a vacuum residue fraction with or without at least partial reduction or asphaltenes; adding a catalyst to the full gasoil and/or to the blend of this with a reduced asphaltenes fraction and subjecting the catalyst-full gasoil and/or deasphalted oil fraction to catalytic steam cracking to form an effluent stream; separating the effluent stream into a gas stream and a liquid stream; and mixing the liquid stream with the light fraction and the vacuum residue fraction to form an upgraded oil. The system includes hardware capable of performing the method.
