    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: 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.
