Aspen HYSYS User Certification (ACU)

Explore the propane refrigeration cycle components, including a compressor, condenser, joule-thomson valve, and evaporator, and how propane absorbs heat in a closed loop.

simulate a propane cycle in Aspen HYSYS with Pink Robinson fluid, modeling four material streams and unit operations, including valve, heater, compressor, and condenser.

Customize the Aspen HYSYS workbook by adding a streams tab with material stream properties like molar heat capacity, mass heat of vaporization, and mass density. Save the updated workbook.

View and monitor material stream composition and unit operation data in the Aspen HYSYS simulation by using workbook tables, show table, and add/delete actions.

Learn to create and save a template in Aspen HYSYS by converting a simulation case to a template and defining heat streams to study how heat affects molar flow.

Explore how to maximize natural gas methane content by cooling, condensation, and separation in a gas plant simulation, using heat exchangers, chiller, and low temperature separators to produce sales gas.

Define a gas plant fluid package with detailed composition, export it for reuse, then design a refrigeration flow with separators, heat exchanger, cooler, and energy stream to solve the simulation.

Apply a balance operation in Aspen HYSYS to create a second stream with the same flow and composition, at 6000 kPa, yielding a dew point of -19.8 C.

Add a process template by creating a sub flowsheet within the flowsheet, selecting between standard sub flowsheets, and configuring inlets, outlets, and fluid packages for reuse.

Learn how to enter a petroleum assay in Aspen HYSYS, specifying distillation cuts by volume with boiling point ranges, and explore single-stream vs multi-cut options for distillation data entry.

Create an Aspen HYSYS simulation of natural gas liquid feed, including valve, compressor, pump, heat exchanger, heater, and a distillation column with condenser and reboiler, using Pink Robinson.

Learn to locate heat exchanger duties in performance, perform stream analysis for critical properties, and assess how spec adjustments affect column duties and compressor efficiency with vendor curves.

Explore two-stage compression with staged compressors, coolers, and separators to control vapor and liquid separation. Follow how mixers and recycle units reintegrate condensate into the feed across separators and stages.

Model a feed in Aspen HYSYS for a two-stage compression, raising pressure from 250 psi to 1000 psi, using nitrogen, carbon dioxide, and hydrocarbons with mixers, separators, coolers, and recycle.

Learn to design a recycle loop in Aspen HYSYS, using let-down valves to equalize pressure between a high-pressure separator and mixers, with solve and save steps.
