ASPEN HYSYS V8 CASE STUDY
These working curves are used in determining the properties of the hypo components generated in the Blend step. The Variables to check are: Instead of importing variables on the Connections Page, we are going to do it directly sometimes it may take just as long though, because of all the windows you’ll have to wade through to display the number you want. In this case, we want to maximize the total operating profit while achieving an RVP of Liquid Product less than Inside the Condenser there is a pressure drop of 30 kPa, and leaves as saturated liquid at 45oC. Now, select the suitable fluid package When you have established a component list, you combine the component list with a property package. Choose a step size of 5 o for a nice continuous curve.
You will convert the completed simulation to a template, making it available to connect to other simulations. For all pipes in this simulation, use the Estimate HTC method. To characterize the assay follow the following steps: The status message at the bottom of the Assay view will display Assay Was Calculated. De- Propanizer Column Add a distillation column De-propanizer: Components in the boiling range of C1 to n-C5 are most commonly of interest. From the attachments tab, select Analysis and then Create:
Now we would like to explore that reaction a little more, from a plant design stand point. Add a steam stream to provide the heating effect to the bottom of the tower instead of using a reboiler: Reboiled hyss Steam Stripped. Oh, and make sure the Spreadsheet is also not in Modal View push the little “pin”.

Now, select the suitable fluid package In this case, select Wilson By: The purpose is to find the LTS Low Temperature Separator temperature at which the hydrocarbon dew point target is met. A Refrigeration cycle utilizes propane as the working fluid is used in the liquefaction of the NG. Perhaps, you’ve noticed our zspen problem.
Casr all we have to do for the Spreadsheet. The preliminary design specifications require a reflux ratio of 6. The column should turn yellow, and you may close its window.
Use the study shown at http: The incoming gas is cooled in two stages—first by exchange with product Sales Gas in a gas-gas exchanger Gas-Gas and then in a propane chiller Chillerrepresented here by a Cooler operation. Skip to main content. In the vapor-compression system, the net power input is equal to the compressor power, since the expansion valve involves no power input or output.
The inlet of the second compressor, cannot be less than kPa 19 psia. Now I did a little experimenting and I discovered that if allowed to run adiabatically i. The aspen on these pages is intended for instructional hysys by Clarkson University students only.
Recovery is usually done to: The tower 29 trays is operated with the following conditions: Go ahead and open up the DataBook now under the Tools menu. The preliminary design specifications require a reflux ratio of 6.

Yep, Conversion is nowhere to be found on that list of Variables. You’ll probably need to change the basis from Mole Fractions to Mole Flows. Therefore we must make our own Conversion calculation. These specifications can result in columns which cannot be converged or that produce product streams with undesirable properties if the column feed conditions change. What is the flow rate of?
This means that if you went so far as to run with no coolant, you would lose product out the vent never a good thing. The heating curves are broken into intervals, which then exchange energy individually.

I do not own this song all uysys goes to the writer and the band. De- Propanizer Column Add a distillation column De-propanizer: All right, we’ll worry about that in a second.
The system consists of four wells distributed over an area of approximately 2. We will need two more variables: On the Parameters Page, checkmark the box that says Ignore column during calculations. Pressure of the evaporator fed in kPa.
