    Hello Akeeb, how are you? I hope you and your family are safe.

    I was researching about this subject, and I found a very good post about this matter written by a brazilian process chemical engineer named Jeferson Costa. If you want to know more about him, check his LinkedIn profile here. All credits goes to him and it's his text. If you want to know more and learn more, contact him. I'm just sharing a piece of knowledge I judge useful to you.

    " "Good morning Sir, I have seen that knowing Aspen Hysys alone, is not enough to be a good Chemical Engineering plant designer. Please I'll like you to kindly give me an outline of the different Chemical Engineering Simulation softwares and what they are used for. Like; Coco, Dwsim, Aspen Hysys, Chemcad, Pro ll etc. Thank you " 

    I am not sure if you have the same kind of question. If you follow my post, I hope not.

    Process simulation software is just a small part of plant design. It is a tool to help you perform heat and material balance faster, verify impact of disturbances in your process, size some equipment and evaluate the operation and performance of existing systems. But the process simulation software is worthless if you do not know what to do with the results or how to add the inputs.

    There are many process simulation software in the market and each one of them claim to be the best solving some process issue. If you try to learn them all, you will not have time to learn what really matters in plant design. Know how to develop process engineering deliverables.

    In my point of view, you should focus on only one process simulation software, it can be the Aspen Hysys, the most used one as per observation. I do not have statistics. The benefits of learning Aspen HYSYS is that most of your knowledge you can transfer to Unisim Design. The worst part is that as a commercial software most people will have access to it if they are already working, in Universities or if they look for cracked versions in YouTube, Blogs and Facebook groups.

    On the other hand, a process simulation that has been increasing its importance in the market is DWSim. It is free to download and use and very similar to Aspen Plus. So my suggestion to you is if you do not have access to Aspen HYSYS, go with DWSIM. (You can link to download DWSim in my Blog).

    However, no matter the process simulation software you choose, you will not solve the most important issue: how to prepare yourself to develop process engineering documents to plant design.

    To solve that you need to have access to real cases, get familiar with engineering deliverables, practice and have someone to clarify your questions.

    That´s why I develop Aspen HYSYS Applied to Plant Design. To guide my students through step by step of a plant design working process. Let me give you an example, what is the first subject you should learn for plant design? (it applies to operations also). Reactors, Distillation Column, Dynamics? NO ONE OF THEM.

    You must know first how to deal with the Piping System because without them you will not be able to transport fluid from a point to another. You may never see a reactor in your plant, nor have a distillation column in your process, however, for sure you will find many pipes and fittings in an industrial plant. Chemical engineering courses do not teach you about that. If you are a fresh engineer, probably you have never seen a piping isometric nor a plot plan.

    So it is what Aspen HYSYS Applied to Plant Design will give you. The opportunity to have a senior process engineer as your mentor to teach what you really need to know to work with plant design, step by step."

    I hope this can give you some help. Any doubts just get in touch!

    Thanks bro I really appreciate
     I will link up with the Brazilian guy. His he really accessible
