De- Propanizer Column Add a distillation column De-propanizer: Skip to main content. This example will build on the simulation you made for the Chemicals Tutorial Case from Chapter 4 of the Tutorials Manual. Now you can return back to the spreadsheet to observe the results: Even though the vent is nominally empty, we need to include it on the off chance that some of the reactor contents do become vapourized.
However, the more information you can supply about the fluid, the more accurate these properties will be, and the better HYSYS will predict the fluid’s actual behavior. Go back to the Case Studies Page actually you might first want to make a recording on the Data Recorder Page, as that is a good habit to get into. Each pipe section and fitting is labeled as a segment. For all pipes in this simulation, use the Estimate HTC method. 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 Chiller , represented here by a Cooler operation. The heating curves are broken into intervals, which then exchange energy individually. Since it is the same variable, despite the slightly different nomenclature, HYSYS will change one when it changes the other.
Tears – Adam Saleh. In effect, this process adds to the reflux between these two stages.
Once the Assay is calculated, the working curves are displayed on the Plots and Working C u r v e s tabs. You will convert the completed simulation to a template, making it available to connect to other simulations. A Balance operation will be used sgudy evaluate the hydrocarbon dew point of the product stream at kPa.
In this module, a column will be modeled to separate Light and heavy components from each other using a distillation column with 12 trays. The feed stream enters an inlet separator, which removes the free liquids. Learning Objectives Once you have completed this section, you will be able to: An alternative approach is to specify either component fractions or component recoveries for the column product streams. This can be done in a study hysys.
On Components click on Add, select water, and case x. Yep, Conversion is nowhere to be found on that list of Variables.

After adding the labels, import the variables in each labeled cell: Utility costs, and other issues, are directly tied to the temperatures we use for various operations. Where the sensitivity runs only solve as much of the flowsheet as they need to to get all the dependent variables, Case Studies in HYSYS apparently solve the entire flowsheet every time. That’s all we have to do for the Spreadsheet. Now, select the suitable fluid package In this case, select Peng-Robinson By: What is the flow rate of?
Finally add the hypo component to the component list By: Now, select the suitable fluid package In this case, select Wilson By: Uses provided information with simplified heat exchangers, reactors, separators etc.
Now we are finally, finally ready to set up the Case Study normally it is not at all this much of an ordeal. As you shall see o F is more than sufficient for an upper bound.
You will begin by building a simple column and continue by adding side operations to the column. These include naphtha, kerosene, hyzys diesel, heavy diesel and AGO. De- Ethanizer Column The outlet from the pump is then fed to the de-ethanizer: Well just in case you didn’t, the example consisted of using a CSTR to react Propylene Oxide with Water to make Propylene Glycol, then separating that out as a product.

Go ahead and look at the other pages before you close the Spreadsheet window. Cost Productivity 7 By: In general it is a good idea to be aware of your settings before running a case study as the Case Study will not return you to your original state afterwards. In this module, you will construct, run, analyze and manipulate an Atmospheric Crude Column simulation. Percentageand the Variable Name: Also, though the manuals state that you should be able to delete individual points, I was unable to do so the Delete key at the bottom of the window erases the whole Case Study, so don’t try that.
After running the column, add a pump to transfer the bottom liquid to the De-ethanizer:
