Aspen Hysys User Certification Exam Questions [repack] -

Story: You're a process engineer at a large petroleum refinery, and your team is tasked with optimizing the production of gasoline and diesel fuel from a new crude oil source. The refinery's existing process simulation model, built using Aspen Hysys, needs to be updated to accurately represent the new feedstock. Your supervisor asks you to review the existing simulation, make any necessary changes, and validate the results against laboratory data. You're familiar with Aspen Hysys, having used it for similar projects in the past, but you know that achieving certification as a skilled user will require you to demonstrate your expertise in applying the software to complex process simulation and analysis tasks. Task: Your task is to:

Create a new simulation case in Aspen Hysys, using the refinery's existing simulation as a starting point. Update the feedstock properties to reflect the new crude oil source, using data provided by the laboratory. Modify the process configuration to account for changes in the refinery's operations, including the addition of a new distillation column. Run the simulation and analyze the results , comparing them to laboratory data to validate the accuracy of the model.

As you work through the task, you encounter several challenges:

The new crude oil source has a higher sulfur content than previous feedstocks, which may affect the accuracy of the simulation. The laboratory data provided is in a format that needs to be converted for use in Aspen Hysys. The new distillation column requires specification of additional parameters, such as reflux ratio and tray hydraulics. aspen hysys user certification exam questions

To overcome these challenges, you apply your knowledge of Aspen Hysys and process simulation:

You use Aspen Hysys's Component Plus model to accurately represent the complex phase behavior of the new crude oil source. You import the laboratory data into Aspen Hysys, converting it to a compatible format using the software's Data Import tool. You specify the new distillation column parameters, using Aspen Hysys's Distillation module to design and rate the column.

After completing the simulation and analysis, you obtain the following results: Story: You're a process engineer at a large

The simulation accurately predicts the yields and properties of the gasoline and diesel fuel products. The model shows that the new crude oil source will require adjustments to the refinery's operating conditions to maintain product quality.

By successfully completing this task, you demonstrate your expertise in:
