For more information on the special functions and logical expressions you may use, press Function Help Overhead vapor rate 0. Component Mole Component Mole N2 0. Condenser Temp 46 oC Reboiler Temp Home Presentation on business plan Pages Dc ielts essay BlogRoll persuasive essay outline apa format asean thesis resume writing service long island case study of chronic kidney disease stage 5 developing a research proposal. The two specifications are the target that you want to achieve from the column.

Start by opening up the file you made from the Tutorial. A water draw stream is required to remove the condensed steam from the overhead condenser. The crude is the feed stock to oil refining process. The inlet of the second compressor, cannot be less than kPa 19 psia. What is the flow rate of? The composition of the four wells is the same:

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.

Now, select the suitable fluid package In this case, select Peng-Robinson By: On the Reactions Page, you can see that the current Liquid Volume is ft 3 studyy that the current conversion in the reactor is When you are finished, the page should look like it does below Note that the conversion, in red because it is a spreadsheet calculated value, is the same as we saw it on the Reactor’s Property View.

We’re done with the example. The status message at the bottom of the Assay view will display Assay Was Calculated. Now, select the suitable fluid package In this case, select Wilson By: If you do not have such a file you may start from my version entitled ChemicalsEx. Use cold properties analysis to see the current Reid Vapor Pressure for the liquid product from the third separator: Overhead vapor rate 0.

De- Propanizer Column Add a distillation column De-propanizer: By Hugo Fernando Solis. Add hysus mole fraction for the inlet stream By: Now we would like to explore that reaction a little more, from a plant design stand point.

Once the Assay is calculated, the working curves are displayed on the Plots and Working C u r v e s tabs. Specify the following information for the segment. The Optimizer owns its own Spreadsheet for defining the Objective Functions as well as any constraint expressions to be used. You should now have a Basis-1 fluid package for the process streams and a Basis-2 fluid package hgsys water-steam.

Begin by adding a Spreadsheet to the simulation on the Object Palette.

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. Uses provided information with simplified heat exchangers, reactors, separators etc.

Following are instructions for cooling water and heating steam required by heat exchangers. I have included this second Case Study in my file containing this completed example, CaseEx. In general it is a good idea to be aware of your settings before running a case study studj the Case Study will not return you to your original state afterwards.

However, condensers are usually located on the ground for easy access for maintenance. You should see a nice, pretty 3 dimensional graph of Conversion vs.

If the condenser is aspen above the top of the column, you would expect the same thing for a condenser, i. Therefore we want our maximum temperature to be less than o F.

The built-in property packages in HYSYS provide accurate thermodynamic, physical and casee property predictions for hydrocarbon, non-hydrocarbon, petrochemical and chemical fluids. Components in the boiling range of C1 to n-C5 are most commonly of interest. The preliminary design specifications require a reflux ratio of 6.

Component Mole Component Mole N2 0. Since the general rule goes, the bigger the piece of equipment, the more expensive it is, we’d like to see how sensitive the reaction is to the size of the reactor.

Peng Robinson – Calculate the duty rejected from the chiller ……………… – Calculate the duty Absorbed inside the Heater …………… By: All pipes are uninsulated Consider inner and outer HTC and the pipe wall in heat transfer estimation.

The Pipe Segment is not yet able to solve because we have not specified any information about the heat transfer properties of the pipe. Estimate the costs of all utilities and equipment using the methods in the study and at http:
