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:. Pressure of the evaporator fed in kPa. The first thing we should do is refresh ourselves on the current conditions, so open the Reactor ‘s Property View. On the Reactions Page, you can see that the current Liquid Volume is ft 3 and that the current conversion in the reactor is The Pipe Segment is not yet able to solve because we have not specified any information about the heat transfer properties of the pipe. The working curves are regressed and extrapolated from the Assay input. Typically located after the Desalter and the Crude Furnace, the Atmospheric Tower serves to distil the crude oil into several different cuts.
The Pipe Segment is not yet able to solve because we have not specified any information about the heat transfer properties of the pipe. You may see the new values for the variables from the Variables tab: As we see, when the temperature increases the liquid flow rate decrease, the liquid start to decrease oC, and 15 oC there will be no liquid product and all the product will be vapor. Oh, and make sure the Spreadsheet is also not in Modal View push the little “pin”. The first thing we should do is refresh ourselves on the current conditions, so open the Reactor ‘s Property View. Another big issue is Capital Costs.
Now add a material stream to define the feed stream composition and conditions By: 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. Let’s go ahead and get the Liquid Percent while we are here.
The reflux ratio and the distillate rate under the specified conditions. Learning Objectives Once you have completed this module, you will be able uysys Conversion as the variable go ahead and change the Variable Description at the bottom to just Conversion.

There are two variables called Liquid Percent: Inside the Condenser there is a pressure drop of stud kPa, and leaves as saturated liquid at 45oC. Perhaps, you’ve noticed jysys first problem. Once you have inserted all [URL] reactors and separators into your new pfd, you can begin substituting real heat exchangers for cases and studies. This is not a desired condition for the inlet of a compressor. You’ll probably need to change the basis from Mole Fractions to Mole Flows.
Ahmed Deyab Fares – http: Components in the boiling range of C1 to n-C5 are most commonly of interest.
The system consists of four wells distributed over an area of approximately 2. What is the maximum profit if you adhere to this guideline?
The condenser and reboiler pressures are and psia, respectively. If this happens, try optimizing your reactor in a aspen case using the same reactor feed conditions.
Again, I don’t nysys why, I’m just reporting what I saw and warning you to be aware that the data you get may possibly be buggy. For all pipes in this simulation, use the Estimate HTC method.

Checkmark the reactor temperature and level as independent variables and the convesion as a dependent variable. An alternative approach is to specify either component fractions or component recoveries for the column product streams.
Yep, Conversion is nowhere to be found on that list of Variables. And where do we get to make our own calculations? The two specifications are the target that you want to achieve from the column.
We will need two more variables: Now, in cell B6enter the following v These petroleum hypocomponents provide the basis for the property package to predict the hsys thermodynamic and transport properties necessary for fluid modeling.
In this case, the temperature we set for our reactor determines how much coolant is required and has a direct effect on how well the column runs, and of course, it has a critical effect on the reaction itself. The De-Methanizer reboiled absorber has the following specifications: The database consists of an excess of components and over fitted binary coefficients.
Skip to main content. This is the reason that that is not the variable we really wanted to use. Go ahead and look at the other pages before you close the Spreadsheet window. These specifications can result in columns which cannot be converged or that produce product streams with undesirable properties if the column feed conditions change. All right, we’ll worry about that in a second. Remember me on this computer.
