摘要: A process comprises contacting a hydrocarbon feed with an FCC catalyst in an FCC reactor at reaction conditions that cause at least a portion of hydrocarbons from the hydrocarbon feed to undergo catalytic cracking reactions to a cracking effluent comprising the light olefins separating the cracking effluent in a cracking effluent separation system to produce a light olefin effluent and a plurality of FCC naphtha fractions, recycling at least two of the plurality of FCC naphtha fractions back to the FCC reactor, and injecting each of the at least two of the plurality of FCC naphtha fractions at a different location within the FCC reactor based on reactivity of each of the at least two of the plurality of FCC naphtha.

摘要: The present invention refers to an integrated operation method of conventional and residue FCC units that applies a model developed for predicting the catalytic performance of residue FCC units with any content and quality of flushing for the correct prediction and optimization of process simulators for residue FCC units and refining production planning models. The application can be for individual studies in process simulators or in digital twins to mitigate the unreliability in the prediction of the original simulator for studies with wide alteration in the content and quality of the flushing. The other application consists of modifying the refining production planning models based on the simulation result obtained in the modified process simulators to predict the performance of the waste units operating for any variation in the content and quality of the flushing catalyst used. The refining production planning model allows: 1. Indicative of potential profitability gain; 2. Optimum replacement of virgin and flushing catalysts in the conventional and residue FCC units; 3. Better distribution of the flushing content and flushing quality for FCC consumer units of the flushing system; 4. Quantifies the marginal value of flushing generated in the FCCs units that produce flushing; 5. Defines the best virgin catalyst budget and predicts the logistical costs of transporting flushing between the FCC units producing flushing and consuming flushing, considering all viable routes.

摘要: Assemblies and methods to enhance control of a fluid catalytic cracking (FCC) processing assembly associated with a refining operation, may include supplying a hydrocarbon feedstock to one or more first processing units associated with the refining operation. The assemblies and methods also may include conditioning a hydrocarbon feedstock and unit 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 hydrocarbon feedstock properties and the unit material properties, the FCC processing assembly, so that the prescriptively controlling results in enhancing accuracy of target content of materials produced by the FCC processing assembly, thereby to more responsively control the FCC processing assembly to achieve material outputs that more accurately and responsively converge on target properties.

摘要: A method for thermal processing and catalytic cracking of a biomass to effect distillate oil recovery can include, particle size reduction. slurrying the biomass with a carrier fluid to create a reaction mixture, slurrying a catalyst with a carrier fluid to create a catalyst slurry, heating the reaction mixture and/or the catalyst slurry, and depolymerizing the reaction mixture with the catalyst. The reaction mixture can undergo distillation and fractionation to produce distillate fractions that include naphtha, kerosene, and diesel. In some embodiments, thermal processing and catalytic cracking includes vaporization of the biomass followed by distillation and fractionation. In some embodiments, a resulting distillate can be used as a carrier fluid. In some embodiments, the method can include desulfurization, dehydration, and/or decontamination.

摘要: A process is provided for producing a liquid hydrocarbon material suitable for use as a fuel or as a blending component in a fuel. The process includes co-processing a pyrolysis oil derived from a waste plastic raw material and a biorenewable feedstock comprising triglycerides in a catalytic cracking process in a presence of a solid catalyst at catalytic cracking conditions to provide a cracking product. The cracking product may be fractionated to provide at least one of a gasoline fraction and a middle distillate fraction.

摘要: Systems and methods for enhancing the processing of hydrocarbons in a FCC unit by introduction of the coked FCC catalyst from the FCC reactor and a renewable feedstock to the FCC regenerator to facilitate regeneration of the coked FCC catalyst. The renewable feedstock can contain biomass-derived pyrolysis oil. The biomass-derived pyrolysis oil and coke from the coked FCC catalyst are oxidized by oxygen to provide a regenerated catalyst that is recycled to the FCC reactor.

摘要: A plant or refinery may include equipment such as condensers, regenerators, distillation columns, rotating equipment, compressors, pumps, turbines, or the like. Different operating methods may impact deterioration in equipment condition, thereby prolonging equipment life, extending production operating time, or providing other benefits. Mechanical or digital sensors may be used for monitoring equipment to determine whether problems are developing. For example, sensors may be used in conjunction with one or more system components to perform invariant mapping, monitor system operating characteristics, and/or predict pressure, volume, surges, reactor loop fouling, gas quality, or the like. An operating condition (e.g., of one or more pieces of equipment in the plant or refinery) may be adjusted to prolong equipment life or avoid equipment failure.

摘要: A plant or refinery may include equipment such as condensers, regenerators, distillation columns, pumps, slide valves, or the like. Different operating methods may impact deterioration in equipment condition, thereby prolonging equipment life, extending production operating time, or providing other benefits. Mechanical or digital sensors may be used for monitoring equipment to determine whether problems are developing. Specifically, sensors may be used in conjunction with one or more system components to predict and detect slide valve sticking. An operating condition of the plant or refinery may be adjusted to prolong equipment life or avoid equipment failure.

摘要: Process for evaluating the catalytic performance of a porous solid using a vapor diffusion technique, where a probe molecule and a molecule for dead-time determination is injected into a carrier gas that is then contacted with the porous solid in a vessel, where a detector analyzes the peak width and retention time of a probe molecule and the retention time of the molecule for dead-time determination in the gas exiting the vessel.
