Hysis

Can any one tell me about hysys, what are its best tools and how we can use efficiently pls provide a very detailed answer thanks

Hysys is a Process Simulation tool, which can only be used efficiently and properly if you understand your process well. For example if you need to estimate the efficiency of a compressor, you should actually have some know-how about compressor operation.i.e., what is stage efficiency? What is polytropic efficiency? What data you need to have to analyze certain type of data? The degree of freedom of the compressor operation. Overall, you need to be a good process engineer to simulate any process in Hysys. If you agree with this, you can go to the Aspentech site and download presentations on different equipment models in Hysys. If you have a lisence of HYSYS simulator then sure you should have Username & Password to enter "http://support.aspentech.com/" otherwise ask your licenser.

Yes imran is right regarding usage of Hysys or any simulation software. Prior to use any simulation software, you have to understand the process details properly, so that you can provide valid inputs to software for results to be accurate. Anyhow I have attached a slideshow for a quick start. Hope this will help you. Start your simulation for your desired project and then ask if you have any issue

I think effective use of HYSYS requires as a minimum some basic understanding of "Equations of state" and also degree of freedom analysis of any situation.
Behind every fluid package in HYSYS there is an equation of state having its strenghts and limitations.
You can study equations of state in any book of thermodynamics.
Effective use of any tool is strongly associated with understanding of its limitations. For HYSYS you can only understand limitations if you have some back ground of equations of state. Whene ever you start using a new software go for what is happening at its back-end, how it is computing things and what equations it is using, this information is often provided in help of the software. Knowing the equation would help you decide where to apply it and where not.
Garbage in garbage out....
Understanding your process well is the next step as already explained above.

I think its quite efficiently explained by imran, tousif and wasim about the use of Hysys and a little background or pre-requirements for the use of not just Hysys but any other simulation software...

The most important think to consider, is the understanding of the process you wish to simulate, including every single detail like the applicable laws, the charchteristics of your process, thermodynamics as well the equations of state. Hysys is not a charmed lamp that could give results just by punching ur process inputs. You need to understand your process completely. If you dont, you might get a simulation but you cant be sure of the fidelity of the results you've got.

So the nut shell is, to start with:

1.0 The basics of your process
2.0 The basic interaction to Hysys
3.0 Try some examples of basic process simulations in Hysys

4.0 Now its time to try your own simulation.

Thankyou very much all of you...
