ASPEN HYSYS V8 CASE STUDY

We are going to do things a little differently from the way we did things in the SET example with the Spreadsheet. On the Variables Page, you should see three variables already defined. Perhaps, you might want to develop the habit of always making a record in the Data Recorder also part of the DataBook right before running your Case Studies. The tube outlet from the HX is then sent to a desalter which is simply modeled as Three Phase Separator where desalted water, oil and gas is separated. The cold stream is then separated in a low-temperature separator LTS.

On the Parameters Page, checkmark the box that says Ignore column during calculations. Therefore we want our maximum temperature to be less than o F. On the Worksheet Page, you can see that currently the entire contents of the reactor are exiting via Reactor Prods Reactor Vent has zero flow at o F. A Balance operation will be used to evaluate the hydrocarbon dew point of the product stream at kPa. These working curves are used in determining the properties of the hypo components generated in the Blend step.

Choose a step size of 5 o for a nice continuous curve. Specify the following information for the segment. The following figure shows the physical configuration of this system superimposed on a topographic map.

You may see one, as in my graph, or even two anamalous points.

It’s easy, because the variables hysy already defined, and it’s informative. Refrigeration is used to cool gas to meet a hydrocarbon dewpoint specification and to produce a marketable liquid. Specify the following information for the segment. HYSYS includes additional modelling and decision support tools that can be used to enhance the usability of your models.

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. Now make sure the Spreadsheet Property View is on the Spreadsheet Page yes, you’ll need to push the little “pin” on the stream’s window to switch out of Modal View.

Case Studies Example

The purpose is to find the LTS Low Temperature Separator sspen at which the hydrocarbon dew point target is met. Components in the boiling range of C1 to n-C5 are most commonly of interest.

Components in the boiling range of C1 to n-C5 are most commonly of interest. You should see a nice, pretty 3 dimensional graph of Hjsys vs. A simple three-stage separation with heating between each stage is used and the object of the exercise is to select the let-down pressure and temperatures such that the products revenue less the utilities cost is maximized.

Refrigeration is used to cool gas to meet a hydrocarbon dewpoint specification and to produce a marketable liquid. Each pipe section and fitting is labeled as a segment. The heating curves are broken into intervals, which then exchange energy individually. Typically located after the Desalter and the Crude Furnace, the Atmospheric Tower serves to distil the crude oil into several different cuts.

In the Stream Name column, enter the name Raw Crude to which the oil azpen will be transferred. The condenser and reboiler pressures are and psia, respectively.

Start by opening up the file you made from the Tutorial. In the Stream Name column, enter the name Raw Crude to which the oil composition will be transferred. The tower 29 trays is operated with the following conditions: The feed stream enters an inlet separator, which removes the free liquids. There are two variables called Liquid Percent: De- Propanizer Column Add a distillation column De-propanizer: Hint, hint, wink, wink, nudge, nudge.

Checkmark the reactor temperature and level hsys independent variables and the convesion as a dependent variable. In effect, this process adds to the reflux between these two stages.

Case Studies Example

Heat Exchanger Design Specifications: This is the reason that that is not the variable we really wanted to use. Speaking of which, go ahead and add for that cell the Variable Type: Temperature of the valve outlet in oC.

Now, select the suitable fluid package When you have established a component list, you combine the component list with a property package.
