Dear RG,
I am working on the waste gas from the refinery to electricity production. I propose to utilize Aspen Hysys Model from where conventional exergy will be evaluated. However, I'm unable to make real progress on the part of Advanced Exergy in my initial dry-run following the challenges I'm having to determine the unavoidable exergy of my components. I have the following challenges: (1) Is it possible to use Hysys as a thermodynamic tool to calculate unavoidable exergy (advanced exergy) for my components? If Yes, how is it done? If not what thermodynamic tool can I use?
(2) The mathematical (Graphical) approach for Unavoidable exergy calculation appears to me to be more straightforward from the several journals I have read. But unable to determine the straight-line graph despite defining the ideal operation of each of the components. Therefore, I would appreciate it if you can take out a few minutes of your time to provide me with a clear guide to enable me to unveil the challenge I am experiencing with the concept of Advanced exergy splitting calculation. I appreciate your kind feedback and the wonderful work and contributions you have been making to the engineering world.

There are various designs of waste heat boilers to generate power. Gas flaring adds to global warming and energy should be utilized.
