摘要： A process for pyrolysis of a mixed plastic stream that contains polyvinyl chloride (PVC) is provided in which the chloride from PVC is removed from an initial melting reactor that heats the mixed plastic stream to a sufficient temperature to produce HCl but at a low enough temperature to avoid production of organochlorides. Chloride is primarily removed in a vapor stream from the initial melting reactor, while additional chloride removal may be removed downstream from the melting reactor by the use of sorbent addition to the pyrolysis reactor and by subsequent adsorbent beds.

摘要： The invention provides methods for treating a source oil phase consisting of heavy oil, bitumen, a mixture of heavy oil and bitumen, a mixture of solvent and heavy oil or bitumen or both. The method comprises: introducing the source oil phase to a heated lower section of a device to provide an interior source oil phase; heating the interior source oil phase so as to thermally separate a light oil phase component therefrom and provide a vaporized light oil; and condensing the vaporized light oil phase on one or more internal cooling fins housed within the upper section of the device, to provide a condensed light oil phase liquid, wherein the internal cooling fins are angled so as to direct the condensed light oil phase liquid downwardly to a light end collection system.

摘要： Catalyst fines can be removed from heavy oils, such as marine fuel oils, by introducing an additive in an effective amount to at least partially remove the catalyst fines, where the additive is an oxyalkylated acid-catalyzed alkylphenol formaldehyde resin and/or a Mannich condensate base resin copolymer.

摘要： The invention provides methods for treating a source oil phase consisting of heavy oil, bitumen, a mixture of heavy oil and bitumen, a mixture of solvent and heavy oil or bitumen or both. The method comprises: introducing the source oil phase to a lower reservoir section of a device, flowing the source oil phase through an array of vertically extending heated pipes with an inert gas so as to thermally separate a vaporized light oil phase component from a heated liquid source oil phase, and segregating fluid flows by density in an upper fluid separating manifold to provide a light product fluid and a heavy product fluid.

摘要： Process and apparatus for recovering a product stream from a waste plastic feedstock and reducing the endpoint of the product stream is provided. A polymer oil is produced as a product stream by pyrolyzing the waste plastic feedstock in a pyrolysis reactor to produce a pyrolysis reactor effluent and passing the reactor effluent stream to a contact condensing column. In the contact condensing column, the pyrolysis reactor effluent stream is separated into a vapor product stream and a liquid product stream. The vapor product stream is recovered from the condensing column and the liquid product stream is passed back to the pyrolysis reactor for further reduction.

摘要： Methods and apparatus for processing hydrocarbon and other feedstocks that contain lighter volatile component(s) along with heavier volatile or non-volatile component(s) and/or contaminant(s). The principal benefit being that a feedstock can be processed and separated into its distinct volatile components down to elemental and/or molecular levels, including the ability to handle the heaviest tars and bitumen within the system. This effectively provides onsite value add to the feedstock resource (minus the waste streams such as water, sulfur, or sand; which may have value as isolated components in their own right). The system is robust and can include innovative hardware, methods, and/or software. The system can isolate water, chemical, various hydrocarbon, and particle contaminants of arbitrary concentrations and sizes. These factors provide for significant increases in processing efficiencies and capabilities in the fields of refining and environmental recovery. In a variety of operating scenarios, near-zero emissions can be achieved while processing.

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.
