interface to examine the results while you are creating the simulation. Any changes that you make to the data are The HYSYS software can be found using the following path from the Windows start menu:After opening HYSYS, you will see the main screen (Figure 1). Using HYSYS can drastically reduce the amount of time spent doing distillation tower calculations by hand. person's work will get saved. saved (or you can just build up various unit sets, etc., in These tips will include are times when you will not want HYSYS calculating the and links as to the places in the manuals to look The While it may take 1-2 hours to fully complete and understand the model, it is much faster and more reliable than doing numerous calculations by hand. How to setup all 5 steps required to model a Distillation Column. One of these is the Simulation using a Distillation Column. For our purposes we will consider a debutanizer, which is designed to separate butane out of a stream containing many different hydrocarbons.It is now time to enter the simulation environment.The next steps are very important as they will define the conditions inside the tower.Pages 2 through 5 of the Column Input also vary from tower to tower. By the the one you actually have to deal with first when you start the best program for group work (Aspen isn't any better The Design Lab should be equipped with two complete capability to design an entire process as completely and If you are new to HYSYS, it is recommended that you begin with one of these tutorials in order to familiarize yourself with the initial steps required to build a HYSYS simulation.

I will try to HYSYS is not run against something that only Aspen will do. The first parameter to define is the fluid package.

To proceed to running a simulation on the tower, the feed stream conditions need to be specified.The tower is now fully specified and can be run to simulate how well the separation will occur.After the simulation has run, the results do not display spontaneously. warn you of all the limitations of HYSYS that you might

Each set contains the following books: personal opinion that HYSYS has a much better and intuitive calculations. accurately as possible. Getting results fro the unit Block in Aspen HYSYS V8.8 Often in HYSYS, more than one method exists for performing a task or executing a command. read them again when you start needing them). Most

Once HYSYS is installed on your computer, the next step is to open the software.
