"gPROMS: The best tool for Advanced process modelling"

5/5

What do you like best about gPROMS?

The best tool available to model, simulate and optimise complex systems. Its powerful built-in solver are excellent for solving systems featuring ODEs and PDEs. Except from standard flowsheeting package, PSE offers the possibility to create default models and libraries custom made to your needs. Its language resembles the way you would write the equations on paper, making it quite easy to master. Probably the most useful features for an industrial or research organisation are the optimisation tool and the model validation feature. The first one, is a very powerful tool with many benefits, as it allows the user to optimise very complex systems, which is impossible with traditional tools. The model validation and parameter estimation tool of gPROMS is essential for any organisation that wants to create its own custom models for their process/technology. It has the potential to lead to very reliable and accurate models, but also minimise the amount of experimental activities that are required to reach the result, leading to large savings in time and money.

What do you dislike about gPROMS?

Personally I do not dislike anything particular about the tool. Of course in order to use it, someone has to be proficient (at least at some degree) with process modelling, programming, advanced mathematics etc. Nowadays, university graduates are more an more capable of using computational and given the extensive customer support given by PSE, it will not be difficult for them to master the software, but I can see why engineers of older generations would find it difficult. So the training required would potentially be a downside, but I believe that it is an investment worth taking. Review collected by and hosted on G2.com.

Recommendations to others considering gPROMS:

I would recommend contacting PSE (the company that developed gPROMS). They provide a plethora of different packages, solutions and support in various levels of your project, so do not hesitate to involve them in your decision making. Review collected by and hosted on G2.com.

What problems is gPROMS solving and how is that benefiting you?

The main problem I solved with gPROMS was to model, simulate and optimise a separation unit operation. The software was a lot more powerful (especially in the solver initialisation and optimisation) compared to the alternatives (e.g. Matlab, ASPEN etc.). It really helped to reduce the time needed to solve the problem as I had to invest way less time to write the solvers myself. Review collected by and hosted on G2.com.
