摘要： A process for removing metals in a petroleum oil material. The process comprises causing the petroleum oil material to react with a removing agent which comprises a phosphoric acid ester. A microwave irradiation environment was created during the reaction to provide the required energy essential for separating such contaminations from the oil chemical network. The process of the invention is applied at ambient pressure and low temperature compared to the conventional metal removal processes. The process of the invention can be readily scaled up and integrated into an industrial facility.

摘要： Systems and methods for producing one or more olefins using waste plastics and used lubricating oil are disclosed. Mixed waste plastic is processed in a pyrolysis unit to produce plastic derived oil. The plastic derived oil is subsequently blended with used lubricating oil to form a mixture. The mixture is then separated into (1) a light-end stream comprising C1 to C8 hydrocarbons and (2) a heavy hydrocarbon feed stream. The heavy hydrocarbon feed stream is then processed to produce a steam cracking feedstock stream. The light end-stream and/or the steam cracking feedstock stream are then flowed into a cracking unit to produce one or more olefins.

摘要： A process for the treatment of a hydrocracking unit bottoms recycle stream, and preferably the fresh hydrocracker feed to remove heavy poly-nuclear aromatic (HPNA) compounds and HPNA precursors employs, in the alternative, an adsorption step which removes most of the HPNA compounds followed by an ionic liquid extraction step to remove the remaining HPNA compounds, or a first ionic liquid extraction step which removes most of the HPNA compounds followed by an adsorption step to remove the remaining HPNA compounds. Ionic liquids of the general formula Q+A− are identified for use in the process; organic polar solvents are identified for removal of the HPNA compounds in solution. Suitable adsorbents are identified for use in packed bed or slurry bed columns that operate within specified temperature and pressure ranges.

摘要： An aromatic imine blend includes an aromatic imine and a de-foaming agent, surfactant, amine, hydrotrope, alcohol, amino acid, ether, alkalinity stabilizer, or a combination thereof. A process of removing carbon dioxide or a sulfide from oil, water, or natural gas includes supplying an oil, water, or natural gas stream and contacting the oil, water, or natural gas stream with an aromatic amine blend. The aromatic imine blend includes an aromatic imine and a de-foaming agent, surfactant, amine, hydrotrope, alcohol, amino acid, ether, alkalinity stabilizer, or a combination thereof.

摘要： The invention provides a process to purify a gas stream by using an adsorbent bed and a secondary device to remove heavy hydrocarbons with a recycle stream then sent first to a vessel containing an amine solvent to remove acid gases including carbon dioxide and hydrogen sulfide and then in most embodiments of the invention sending the treated gas stream to a dehydration unit such as an adsorbent bed or to a triethylene glycol absorbent to remove water. The invention further provides improved integration of the process streams to allow for smaller amine solvent and dehydration units as compared to the prior art.

摘要： Disclosed herein is a kiln 100 for use in the production of hydrocarbon fuels from plastics. The kiln 100 comprises a scrubber 200 in fluid communication with a reaction chamber 130, the scrubber 200 being configured to condense hydrocarbons in the reaction chamber gas product stream 501 above a predetermined upper hydrocarbon range for returning to the reaction chamber 130 for further heating in the absence of oxygen. Also disclosed herein is a method of converting waste plastics to a commercially-useful form by way of diesel or the like. The method comprises treating a crude fuel produced from plastics in a pyrolytic process with a first extraction step comprising counterflow liquid-liquid extraction, and a second extraction step comprising counterflow extraction of solvents from the first extraction step.

摘要： Embodiments provide a method and apparatus for recovering components from a hydrocarbon feedstock. According to at least one embodiment, the method includes supplying a hydrocarbon feedstock to an oxidation reactor, wherein the hydrocarbon feedstock is oxidized in the presence of a catalyst under conditions sufficient to selectively oxidize sulfur compounds and nitrogen compounds present in the hydrocarbon feedstock, separating the hydrocarbons, the oxidized sulfur compounds, and the oxidized nitrogen compounds by solvent extraction, collecting a residue stream that includes the oxidized sulfur compounds and the oxidized nitrogen compound, and supplying the first residue stream to a fluid catalytic cracking unit. The first residue stream is further supplied through a hydrotreater prior to supplying the first residue stream to the fluid catalytic cracking unit.
