Hello,
I am very much interested to see such a project on freelancer as I love working on ASPEN software and being a process engineer in my career I have been doing these things as my daily work. Moreover I am a Process Simulation engineer who decides the feasibility of the prescribed detailed design and still would find a optimized way to enhance the process by all means. You can discuss me about this in person with me to find whether I will be suitable or not and can take a look into my profile for my background. ASPEN Hysys, ASPEN Plus , Flarenet, Aspen EDR are the software packages where I excel.
