CASE STUDY HYSYS V8

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 de-ethanizer has the following specifications: Reboiled and Steam Stripped. As an option, you can aspen on thermosiphon reboilers using, for example, http: Now you can return to the Simulation environment to see the stream Raw Crude with a full composition: Go ahead and open up the DataBook now under the Tools menu. The composition of the four wells is the same:

The incomes from the Plant are both the Gas and Liquid Products. Comp Mol frac Comp Mol frac C1 0. A water draw stream is required to remove the condensed steam from the overhead condenser. With the addition of the appropriate text, your Spreadsheet should now look like this note, if you place an import incorrectly you must delete it from the Connections Page or using the secondary mouse button menu:. The feed stream enters an inlet separator, which removes the free liquids. In this case, we want to maximize the total operating profit while achieving an RVP of Liquid Product less than 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.

Oh, and make sure the Spreadsheet is also not in Modal View push the little “pin”. These specifications can result in columns which cannot be converged or that produce product streams with undesirable properties if the column feed conditions change.

  COURSEWORK EXTENSION DMU

The two specifications are the dase that you want to achieve from the column.

Calculate the temperature of LTS feed ………………. Click here to sign up.

The heating curves are broken into intervals, which then exchange energy individually. Recovery is usually done to: To shorten your simultation time enormously, open the column’s Property View.

Specify the following information for the segment. Now add a material stream to define the feed stream composition and conditions By: For all pipes in this simulation, use the Estimate HTC method. 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.

You may also want to try a two dimensional case study, Coolant Duty vs. Finally add the hypo component to the component list By: Now, select the suitable fluid package In this case, select Wilson By: Hysys revised July 27, aspen Please submit all questions, comments and suggestions to W.

You should see a Bull’s Eye when you are over a place you may “drop” it.

Neglect the pressure drop inside the condenser. Use the study shown at http: 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 stuey every time.

The aspen on these pages is intended for instructional hysys by Clarkson University students only. After adding the labels, import the variables in each labeled cell: Htsys Ethanizer Column The outlet from the pump is then fed to the de-ethanizer: However, condensers are usually located on the ground for easy access for maintenance.

The crude is the feed stock to a Pre-heat Train, followed by the Atmospheric Crude Column, which will be modelled in a subsequent module. Valve pressure drop in kPa. For more information on the special functions and logical expressions you may use, press Function Help Now I did a little experimenting and I discovered stuudy if allowed to run adiabatically i.

Once you have inserted all [URL] reactors and separators into your new pfd, you can begin substituting real heat exchangers for cases and studies. De- Methanizer Column The De-Methanizer is modeled as a reboiled absorber operation, with two feed streams and an energy stream feed, which represents a side heater on the column.

The Blend tab of the Oil Characterization view provides two functions, cutting the Oil into Hypo components and Blending two or more Assays into one set of hypo components.
