Textbook in PDF format The Aspen HYSYS Petroleum Refining Reactor Models are a suite of rigorous equation-oriented models within the Aspen HYSYS Petroleum Refining functionality. Our suite contains all major refinery process units: Fluid Catalytic Cracking, Naphtha Reforming, Hydroprocessing (Hydrocracking and Hydrotreating – including Naphtha Hydrotreating), Delayed Coking, Visbreaking, and Alkylation. The reactor models are designed to be calibrated to match plant data and then used in simulation to predict results under various operating conditions. Therefore, there are two major modes of operation: Calibration and Simulation. In Calibration, plant data is fixed and model parameters move to fit the plant data. In Simulation, the model parameters are fixed and then various plant data is predicted. To model the reactions involved in each process, HYSYS uses a set of "kinetic lumps" to group molecules of a certain type together that undergo the same type of reaction. To establish the composition of the kinetic lumps in the feed stream, HYSYS uses the property information in the feed stream, the composition of the hypothetical and pure components in the feed stream, and in some cases, a feed "fingerprint." The feed fingerprint is a representation of a certain type of feed in terms of the kinetic lumps. The feed fingerprint is used along with the data that you specified or data from the feed stream to properly distribute the feed amongst the kinetic lumps used in the reactor model. The reactor models also predict the properties of the product. These properties are propagated throughout the rest of the flowsheet to supply the appropriate information for downstream unit operations or product blending.
