摘要： The embodiments of the present disclosure relate to a method and system for producing refined hydrocarbons from waste plastics. The method and system for producing refined hydrocarbons from waste plastics according to the present disclosure may minimize formation of an ammonium chloride salt (NH4Cl) and may prevent an adhesion phenomenon of impurity particles in a reactor in a refining process of waste plastic pyrolysis oil containing impurities including chlorine and nitrogen. In addition, the method and system for producing refined hydrocarbons from waste plastics according to the present disclosure may have excellent refining efficiency and may implement a long-term operation of a process because deactivation of a catalyst used in the process is prevented, and may produce refined hydrocarbons having a low content of impurities and a low content of olefins, and solid coke.

摘要： Systems and methods for crude oil separations including degassing, dewatering, desalting, and stabilization. One method includes separating crude oil into a crude oil off-gas and a partially degassed crude oil output; compressing the crude oil off-gas; applying the compressed crude oil off-gas for indirect heating through reboilers of the partially degassed crude oil output; and directly mixing with the crude oil a compressed atmospheric pressure gas. In some embodiments, multiple reboilers are used. In some embodiments, heat exchangers are used. Aftercoolers are used after the compressor to cool the gas; knockout drums are used after the coolers to separate liquids.

摘要： Systems and methods to enhance the removal of inorganic contaminants, including metals, from hydrocarbon feedstocks at a refinery. One or more embodiments of such systems and methods may be used to provide a renewable hydrocarbon feedstock having a reduced amount of metal contaminants. The reduction of metal contaminants in the renewable hydrocarbon feedstock mitigates catalyst fouling and/or deactivation during downstream refinery processing of the renewable hydrocarbon feedstock.

摘要： A crude oil demulsification system includes a vessel. A cyclonic separator is disposed outside the vessel. The cyclonic separator is configured to receive and separate phases of a multi-phase fluid stream into a gaseous stream and a liquid stream that includes a first liquid phase and a second liquid phase by inducing cyclonic flow. A heat exchanger is fluidically connected to the cyclonic separator. The heat exchanger is disposed outside the vessel, and is configured to receive the liquid stream and to heat the liquid stream by exchanging heat with a heating medium flowed through the heat exchanger. An electrostatic coalescer is fluidically connected to the heat exchanger and is disposed inside the vessel. The electrostatic coalescer is configured to receive the liquid stream heated by the heat exchanger and to demulsify the liquid stream by causing coalescence of liquid droplets of one of the first or second liquid phases.

摘要： Embodiments discussed herein relate to systems and methods for separating two or more phases of an emulsion or other mixture. The methods include providing the mixture with a net and unipolar charge (e.g., such that adjacent droplets therein acquire net and unipolar charges), thereby enhancing coalescence of like-phase droplets therein and producing, or enhancing the production of, two or more consolidated phases; and collecting the two or more consolidated phases.

摘要： A method of electro treating tailings in a containment structure to cause a separation of at least some water from said tailings and a consolidation and compaction of at least some solid particles is shown. The method includes placing a plurality of first electrodes in the tailings to be treated generally along one side of a predetermined volume and placing a plurality of second electrodes in the tailings to be treated generally along an opposite side of said volume to the plurality of first electrodes, said first and second electrodes being spaced apart by a predetermined distance. The next step is applying a treatment current across said distance between said spaced first and second electrodes to create an electrical field which causes solids to consolidate at one of said plurality of first and second electrodes; and creating a geotechnical structure within said volume comprised of dewatered solids consolidated from said tailings around one of said electrodes. The geotechnical structure may be a layer at the bottom of the containment structure, along a side of the containment structure or across the top of a containment structure.
