Aspen HYSYS Petroleum Refining (formerly known as "RefSYS") is based on the flowsheet capabilities of HYSYS. Existing HYSYS simulation cases can be leveraged in Aspen HYSYS Refining adding petroleum assays information and specific refinery unit operations. 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. I...
