Aspen Hysys is a simulator that responds to many chemical processes in the oil and natural gas processing industry, different sectors have benefited from this simulator for years, and it is always one of the best options for creating design and simulation processes. For example, simulate a distillation tower, a dehydration plant, etc. Since Aspen added Hysys to its product portfolio, I am more inclined to use it, because it has improved significantly, this simulator is one of my favorites as it shows me the simulated process in a stable and dynamic state, that is, that for my presentations of projects, it allows me to dynamically show the movements in the process so that the jury sees what I really want to solve.

It has nothing that I dislike. I think it has a complete package and a powerful interface that will allow you to have the best of the processes with all its parameters and indicators. Review collected by and hosted on G2.com.

Hysys has been an integral part for my simulation projects. The simulation results are very precise and pilot results are also very much inline. I've used it for distillation columns and single fixed bed reactors. Review collected by and hosted on G2.com.

The user interface could be a little better. Review collected by and hosted on G2.com.

Process calculations are easy to do in ASPEN hysys and it is quite user friendly too Review collected by and hosted on G2.com.

It is bit expensive rather than that there is nothing I dislike Review collected by and hosted on G2.com.

It provides satisfaction for the industrial process and reduce the time for troubleshooting. Review collected by and hosted on G2.com.

It’s all depends upon software and need high level of competence. Review collected by and hosted on G2.com.

Lack of hints, as a relatively inexperienced user in the beginning it was tiring to grab help from the internet or an expert Review collected by and hosted on G2.com.

Its user friendly interface, safety analysis, petroleum assays calculations, flow assurance calculations and above all its optimization calculations Review collected by and hosted on G2.com.

I dont find anything to dislike because its features and benefits are excellent Review collected by and hosted on G2.com.

The best part in aspen is the built in fluid thermo dynamics equation Review collected by and hosted on G2.com.

Actually it is perfect but it needs knowledge in its usage Review collected by and hosted on G2.com.

Its GUI is very attractive and easy to use. Review collected by and hosted on G2.com.

some chemicals related to pharmaceuticals, i could not find. Review collected by and hosted on G2.com.

The program allows for a wide range of simulations that can allow you to perform simple tasks that are normally repetitive as well as extremely in depth optimisation on specific parts of a process, allowing you to see what changes in the system might impact.

The software itself does have a dated looking user interface however this is a very minor issue. The program it’s self could be more user friendly to newcomers as figuring the system out initially can be very daunting. Review collected by and hosted on G2.com.

The layout was easy to understand and create. There were a lot of inbuilt equations that I could use. Review collected by and hosted on G2.com.

Customer service was a little poor. When I encountered a problem, they helped at first. But when I could not solve the problem using the first suggestions, the customer care response had become much slower. Review collected by and hosted on G2.com.
