Software Need Help with My Graduation Project – Aspen HYSYS Simulation

Hi everyone,

I’m working on my chemical engineering graduation project and I’m facing some difficulties with Aspen HYSYS simulation. (( My project is about Analysis and simulation of flare gas recovery in Oil and Gas, and I’m trying to simulate the process described in a research paper using Aspen HYSYS, but I’m struggling to replicate the results and set up the units correctly.))

I was wondering if anyone here has experience with similar simulations and could give me some guidance or maybe share resources/examples.

Any help or advice would be greatly appreciated 🙏

Thanks in advance!

People do this for a living, sure. 

Make it easy for us though.  We need more info on what you are building. 

Describe the model boundaries - what is in scope and what is not. Is it steady state or dynamic.

Hi, thanks for your reply!

Here are more details about my project:

Process: [convert flare gas to gasoline on a research paper]

Scope/Boundaries: I’m including [feed gas preparation.]

Simulation Type: Steady state (not dynamic).

Current Challenge: I’m struggling to replicate the paper’s process in Aspen HYSYS because the process flow diagram is not clear, which is why I do not know what units are used (compressors, heaters, expanders, etc.)

I’d really appreciate any advice on how to properly define the system boundaries and set up the right fluid package so I can move forward.

Share your background

Do you have the basic understanding such as Chemistry: Chemical reactions, Balance

Material Balance, Degree of freedom Analysis?

Sorry mate, you’re going to need to be really specific on what issues you’re having. You probably won’t find anyone here who’s willing to just do your project

Yeah... ask specific questions to address your specific needs.

I presume you have built up your model. Why don't you start there and ask what's in your model that doesn't predict properly?

I want help, not project implementation

Ask specific questions or describe your issues in more detail. Which results are different? What have you done so far? What have you tried?

none can help if they dont know what to help on

Any one of the three main units described in your paper is a full on process, at a former employer this would be three process teams working together. I suggest you drastically cut down the scope of what you're trying to do.

Agreed. One unit alone will have my hands quite full if I were to do this at my work.

Let alone three.

As someone who does Hysys simulation for a living, I'm willing to pitch in. But you gotta give something and not make us hand what you need on a silver platter.
