![]() ![]() Properties saves on the file also the units of measurement so you can define different streams and different units in different projects. ![]() Then select the file "def.ppp" if you wish that Properties utilizes this data as default (this is the normal, recommended option), differently set a different name (you can for example define different names for different projects) but you will need to load that specific Archive before to make calcs for that project and since Excel reloads Properties with any new page this may result tedious. Now you are ready to use Properties for calculating all the properties which you need, however there is still a last thing to do if you do not wish to lose all data when leaving a Excel page, precisely to save data to a file, to save data to a file from Excel Properties menu select "Save a Archive" Here you can select the units which you need for a specific problem, in this example for the pressure (first row) select Bar.a, notice that unit for temperature is K (but you can set the units which you prefer) then click on Ok button to accept new values and leave the Properties editor. Once defined the stream you may wish to define the units which we wish to utilize in our problem, in stream editor go then to the "Units" dialog The fourth page provides access to BIP (Binary Interaction Parameters) for the different models, you can enter specific values or click on "Load BIPs" button to get the predefined BIPs from databank.įinally we must save the new data, in the first page click on "Save" button, note that you can redefine the name of the stream as you wish (editing the cell near the button "Save"), you can define / modify many streams following the procedure described. ![]() In the third page you can define the package (thermodynamic models and related options), here we define API Soave Redlick Kwong. In the second page you can define a new composition or modify an existing composition, in this example we define C1 0.7 CO2 0.15 H2S 0.15 as molar fractions The Stream editor includes several pages, from the first page you can select a stream (Properties can store all the streams required to define a medium size plant) solve a series of flash operations and see the resulting compositions in the different phases, in this page select the stream you wish to define, for example the first. Properties includes a Stream editor which permits to access all informations (as compositions, operating conditions, models, options) for all streams which you need to define, to access the Stream editor from Excel Properties menu select Edit Properties With Prode Properties you can do this in Excel, Matlab or any compatible application including custom software, this example shows how to use these methods in Excel.įirst step: define the stream (components, compositions etc.) Prode Properties can calculate up to 5 equilibrium points along a line with specified phase fraction, in addition there are specific methods for calculating directly Cricondentherm, CricondenBar and Critical points. Prode Properties has specific methods which permit to calculate dew points, bubble points, equilibrium points at specified phase fraction (vapor, liquid, solid **) and pressure (or temperature), typical applications include hydrocarbons dew point (HDP, HCDP), cricondentherm, cricondenbar of natural gas mixtures from gas analysis. Do you need assistance or wish to discuss applications ?Įxcel / Matlab application example : dew point, bubble point, cricondentherm, cricondenbar, critical point ![]()
