This lecture shows how to start a new Aspen HYSYS case, import an assay to create a fluid package, select Peng-robinson for refinery hydrocarbon modeling, and rename the petroleum package.
Import a petroleum assay from the embedded library to attach to a crude material stream, then enter temperature, pressure, and molar flow in the simulation environment.

Learn how to implement trim duty in an atmospheric distillation column using an energy stream to dynamically adjust reboiler duty and column operating conditions in Aspen HYSYS.
Controlling the quality of Naphtha and Kerosene instead of the quantity produced.
Controlling Diesel and AGO quality by setting a cut point instead of fixing the flow rate
Model a vacuum distillation column fed from atmospheric residue, heated by a vacuum heater, with steam and pump around reflux, producing light and heavy vacuum gas oil under pressure profile.
Implement a second bumper round in the vacuum column to handle heavy and light vacuum gas oil, adjusting flow rate and duty within side operation settings.
Import vacuum gas oil as the FCC feed from the library, configure essay lumps, and set top and bottom cut points, then review feed properties before defining the catalyst.
Set the FCC operation by defining feed flow, temperature, and pressure in the riser, specify steam and regenerator conditions, then review yields and heat balance.
Create a hydrocracker template in Aspen HYSYS, configure two reactors with two and three catalyst bits, add a high-pressure separator, and set calibration options for future integration.
Define a component list and the float package for the hydrocracker template. See how the hcr fluid package uses base components and abbreviations such as C6 to model feeds.
Learn to calibrate the hydrocracker in Aspen HYSYS using calibration factors, input operation measurements, feed data, and product specifications, and interpret calibration results from the worksheet and linked Excel sheet.
Set up calibration parameters and objective function for a hydrocracker in Aspen HYSYS, define bounds and initial values, run pre-calibration, review results, and save calibration factors for simulation.
Push calibration data into the hydrocracker simulation, activate the reactor solver, and review hydrocracking results and yields. Save the hydrocracker as a template and integrate it into a refinery model covering desalter, distillation, and heavy vacuum gas oil feed.
