# gPROMS Reviews **Vendor:** Process System Enterprise **Category:** [Oil and Gas Simulation and Modeling Software](https://www.g2.com/categories/oil-and-gas-simulation-and-modeling) **Average Rating:** 4.3/5.0 **Total Reviews:** 25 ## About gPROMS gPROMS has support for multiscale modeling, custom modeling, a full process flowsheet and many more benefits. ## gPROMS Reviews ### 1. Powerful, but use with caution! **Rating:** 3.5/5.0 stars **Reviewed by:** Hessam R. | Research Assistant, Enterprise (> 1000 emp.) **Reviewed Date:** February 09, 2021 **What do you like best about gPROMS?** gPROMS provides unmatched for power and speed, when it comes to modelling and simulation of complex dynamic systems. Part of this strength comes from the implementation of the equation solvers, that are capable of solving even PDEs in a fast and reliable fashion, a feature that even established programming languages such as MATLAB or Python struggle with. Optimization is also uncomplicated and easy-to-implement. The solid object oriented programming style and use of modules makes creating DRY code easier. **What do you dislike about gPROMS?** The error analysis tool is very unforgiving, as it keeps shouting for the smallest mistakes (e.g. fixing an extra variable in an algebraic equation system can lead to 80 unrelated error messages) which can result in painful headaches. The user interface (GUI) is quite basic and has a lot of room for improvements, especially given the fact that occasionally the coding syntax can be unintuitive. Also the user support system is quite ineffective. The coding style in itself is hard to follow, especially without any official or extensive user manual or educational videos published, which is topped by a small user community. Therefore, when facing a challenge it is almost impossible to get help. **What problems is gPROMS solving and how is that benefiting you?** The high speed in solving complex systems and optimization problems is second to none. I used it for a course on dynamic systems simulation. ### 2. gPROMS:The best tool for Advanced process modelling **Rating:** 5.0/5.0 stars **Reviewed by:** Lefteris C. | Enterprise (> 1000 emp.) **Reviewed Date:** January 09, 2021 **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. **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. **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 heped to reduce the time needed to solve the problem as I had to invest way less time to write the solvers myself. ### 3. Easy to model **Rating:** 4.0/5.0 stars **Reviewed by:** Hammad A. | Chemical Process Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** December 13, 2020 **What do you like best about gPROMS?** To insert information and set variables and and other parameters there is very helpful and easy to do and you will get different results by simply changing the variables in your problem and in that way you can generate as many iterations for your problem as you want to. **What do you dislike about gPROMS?** Sometimes it becomes troublesome to identify different parameters, assigning nomenclature to parameters and complete the information for getting results. **Recommendations to others considering gPROMS:** It will help you in your initial modelling of projects and in generarting results for analysis and comparison between different results. **What problems is gPROMS solving and how is that benefiting you?** If you know how to use this software and knows how to insert information and once you have done all this then it is just one step away to get your results. For getting results without this software is a lengthy process ### 4. Great tool for modelling **Rating:** 5.0/5.0 stars **Reviewed by:** Fatemeh A. | Process Development Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** January 08, 2021 **What do you like best about gPROMS?** I used gPPROMS and gCrystal in all my 4 years of PhD and I should say I really enjoyed it since oncevyou learn how to work with it you do not want to go back to other programs **What do you dislike about gPROMS?** Why isn’t it yet everywhere??? I also miss online help when you have problem it is not clear how to solve it **Recommendations to others considering gPROMS:** At first it is not easy to work with it but once you learn the trick you will love it **What problems is gPROMS solving and how is that benefiting you?** I did a lot of crystallization and membrane distillation programming ### 5. Good flowsheeting environment for modelling of novel processes **Rating:** 3.5/5.0 stars **Reviewed by:** Michele T. | Scientific project manager, Mid-Market (51-1000 emp.) **Reviewed Date:** January 19, 2021 **What do you like best about gPROMS?** I find gPROMS is a very useful resource for custom modelling (gPROMS ModelBuilder) and data regression (parameter estimation), to implement user-defined models of non-conventional process units into a full flowsheeting environment, . **What do you dislike about gPROMS?** I think one of the downsides of gPROMS is the proprietary language syntax, which is sometimes less intuitive and compact than C++, for instance. **What problems is gPROMS solving and how is that benefiting you?** I have used gPROMS during my PhD research as main tool for modeling electromembrane processes (electrodialysis and reverse ED). The benefit of using gPROMS was the possibility to implement a custom model of the main process unit (reverse electrodialysis stack), and then run simulations of the whole process. ### 6. I used gPROMS for dynamic modelling of Mathanol Steam Reforming Process....Using EO Approach **Rating:** 4.0/5.0 stars **Reviewed by:** Engr. Anees A. | Chemical Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** January 22, 2021 **What do you like best about gPROMS?** It allows to customize the existing Unit Operation Models in Equation Oriented approach to easily understand what is happening on the backend. **What do you dislike about gPROMS?** Its UI/UX are not modern.It needs further development based improvements in future releases. **Recommendations to others considering gPROMS:** I highly recommend it due to its EO Solution abilities.... **What problems is gPROMS solving and how is that benefiting you?** Unsteady State Mole and Energy Balance for Reactor Design and Process Dynamics and Control Strudy.... ### 7.

Specifically in my case I was asked to come up with an analytical solution for PSA times, and gproms helped me estimate the data for adsorption model including equilibrium and mass transfer resistance, which I used to get an efficiency factor in my analytical formula. ### 8. A logical and enjoyable language for problem solving **Rating:** 4.0/5.0 stars **Reviewed by:** Gaius Z. | Small-Business (50 or fewer emp.) **Reviewed Date:** December 08, 2020 **What do you like best about gPROMS?** The syntax is quite logical and if you are familiar with coding, it's easy to get the hang of it. It can also plot graphical data. **What do you dislike about gPROMS?** It is not as widely used compared to languages such as Java and Python so there aren't too many solutions or advice online **Recommendations to others considering gPROMS:** If you are familiar with programmes such as GAMs and have experience in chemical engineering this programme is suitable for you. **What problems is gPROMS solving and how is that benefiting you?** Grooms has helped me greatly in solving chemical engineering problems such as calculating inputs and outputs of a reaction tank and plotting time derivative graphs. This has been very beneficial because alot of these complex problems require numerical approaches which gProms can handle with ease. ### 9. good and easy to use **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Biotechnology | Mid-Market (51-1000 emp.) **Reviewed Date:** January 07, 2021 **What do you like best about gPROMS?** I love the way it explains process system engineering and the great tuition it has. the variety of examples you can start with and the kindness of customer services. **What do you dislike about gPROMS?** It does not have other things other software might offer like more function like error function etc. it can be used if you are Matlab or python user but not the other way around if i remember correctly. The error message can be more specific and there is a chance for improvement. **What problems is gPROMS solving and how is that benefiting you?** I solve chemical engineering problems and optimise variables. I use it to solve PDEs and ODEs mainly. ### 10.

It is very easy to find out how to solve an optimization problem even if you don’t know how to use gproms in the first place **What do you dislike about gPROMS?** There is not enough documentation online (similar as in Matlab where you can google all your problems). However, since gproms is not as popular I don’t think this is a main issue **What problems is gPROMS solving and how is that benefiting you?** I was using gproms in two of my research projects as a master’s student. I was able to model and optimize my system (enzyme reactors). Gproms was very user friendly and easy to use ### 12.

Fantastic software for process modeling **Rating:** 5.0/5.0 stars **Reviewed by:** Carlos G. | Senior research scientist, Small-Business (50 or fewer emp.) **Reviewed Date:** December 11, 2019 **What do you like best about gPROMS?** I started using gOROMS in 2003 for modeling adsorption processes. Every time we had something that needed a systematic change based on fundamental properties that can be directly translated to equations, we could implement it. This is why after so many years and different working environments, is the software I use. **What do you dislike about gPROMS?** After many years, what I know is that when I can’t get convergence, most of the times is my fault. So I can’t point out specifically a weakness. **Recommendations to others considering gPROMS:** 1- you like equations? You can literally write them in the code as they look on paper. 2- there are good examples to start, so is easy to learn. 3- I’m probably biased because I use this for > 15 years, but is a great software in my opinion. **What problems is gPROMS solving and how is that benefiting you?** We do adsorption processes mostly. In last years we have benefited from the PML libraries allowing us to make full simulations. ### 25.
