Abstract: Described herein is a combined process for improved hydrotreating of diesel fuels, in which the feed to be hydrotreated is pretreated with a selective adsorbent prior to the hydrotreating step to remove polar materials, especially nitrogen containing compounds (N-compounds). The selective adsorption process can employ either liquid or solid adsorbents. After contact of the adsorbent with the diesel fuel feed, the adsorbent containing undesired polar compounds is separated from the diesel fuel. The separated adsorbent is then subjected to a two step procedure for regeneration.

Abstract: Methods and systems for producing pyrolysis products from a mixed plastics stream are described herein. The method may include conducting pyrolysis of a plastic feedstock to produce a stream of plastic pyrolysis oil; feeding a catalytic cracking feed stream and a catalyst from a catalyst regenerator into a fluidized bed reactor, where the catalytic cracking feed stream comprises the plastic pyrolysis oil; cracking the catalytic cracking feed stream in the fluidized bed reactor to produce a product stream and a spent catalyst; and transporting the spent catalyst to the catalyst regenerator and regenerating the catalyst in the catalyst regenerator. The product stream comprises olefins having a carbon number of C2-C4 and distillate fuel.

Abstract: Systems and methods are provided for reducing or minimizing the chloride content of products generated during co-processing of a plastic feedstock (such as plastic waste) in a refinery process. The reduction in chloride is achieved by mixing the plastic feedstock with one or more additional feedstocks for co-processing in a mixing and/or holding vessel that is maintained at a dechlorination temperature that allows for decomposition of chlorine from the plastic feedstock to form HCl, while reducing or minimizing other conversion of the plastic feedstock and/or the additional feedstock. A purge gas can be passed through the mixing/holding vessel to remove the evolved HCl from the vessel. Because the dechlorination temperature is selected to reduce or minimize conversion of the feedstocks in the mixture, the amount of carbon-containing products that are removed with the purge gas can be reduced or minimized. The dechlorinated mixture of plastic feedstock and additional feedstock(s) can then be processed in a convenient refinery process, such as a thermal cracking process (e.g., coking, visbreaking, other types of pyrolysis) or a catalytic conversion process (e.g., fluid catalytic cracking).

Abstract: Provided is a blend of a petroleum feedstock and 1-20 wt. % of plastic, based on the weight of the blend, with the plastic comprising polyethylene and/or polypropylene, and the plastic in the blend comprising finely dispersed microcrystalline particles having an average particle size of 10 micron to less than 100 microns, and less than 10 ppm chloride. A process for preparing a blend of plastic and petroleum is provided, comprising mixing together a petroleum feed and a plastic comprising polyethylene and/or polypropylene and heating the mixture above the melting point of the plastic, but less than 500° F. The blend mixture is then hot filtered with the resulting filtered blend mixture being heated to at least 500° F. The heated mixture can then be treated with a chloride removal guard bed. The resulting blend can then be cooled and stored or sent directly to a refinery conversion unit.

Abstract: The present disclosure relates to an emulsification enhancer, wherein the emulsification enhancer is made from the following components by weight: 3.8-18 parts of melamine, 0.1-2.7 parts of urea, 2-9.6 parts of monoaldehyde, 0.2-8.4 parts of dialdehyde, 0.9-4.8 parts of hydrochloric acid (HCl) and 56.5-93 parts of water. The present disclosure provides a preparation method of the demulsification enhancer and the application of the demulsification enhancer as an auxiliary agent in the improvement of oil demulsification. The demulsification enhancer of the present disclosure can assist a traditional demulsifier to accelerate the three-phase separation of oil, water and sludge in the oilfield produced-fluid, which is helpful to efficiently extract crude oil from oil sludge emulsion layer and water, reduce oil footprint of the oilfield flowing to the environment, reduce energy consumption of crude oil dehydration and carbon emission of the oilfield, and achieve good three-phase separation effect of oil, water and sludge.

Abstract: Assemblies and methods to enhance hydrotreating and fluid catalytic cracking (FCC) processes associated with a refining operation, during the processes, may include supplying a hydrocarbon feedstock to a cat feed hydrotreater (CFH) processing unit to produce CFH unit materials. The assemblies and methods also may include conditioning material samples, and analyzing the samples via one or more spectroscopic analyzers. The assemblies and methods further may include prescriptively controlling, via one or more FCC process controllers, based at least in part on the material properties, a FCC processing assembly, so that the prescriptively controlling results in causing the processes to produce CFH materials, intermediate materials, the unit materials, and/or the downstream materials having properties within selected ranges of target properties, thereby to cause the processes to achieve material outputs that more accurately and responsively converge on one or more of the target properties.
