Logistics component data input method
Thread Content
Does anyone know how to enter the data in this case: given the volumetric flow rate of the logistics stream and the molar concentration of its components; I have no idea about the mass fraction or molar fraction. What should I do?
The flow rate dropdown menu includes an option for volumetric flow rate. It seems that molar concentration can be entered; by the way, if volume flow rate is used, molar concentration is equivalent to volume fraction. Since I haven’t used PROII for a while, here it is for reference
There seem to be two ways for inputting logistics: one is to input the total logistics first and then the proportions of each component, while the other is to input them separately. The original poster just needs to make the right choice~~
This is easy; the molar concentration and volume concentration are the same, so the volumetric flow rate of each component can be determined!
You’ve misunderstood what I meant. What if it’s an aqueous solution of ethanol and propanol, with a volumetric flow rate of 20 m3/h, and the given concentrations of ethanol and propanol are respectively 1 kmol/m3? What should be done in that case?
Move the mouse to the input field located after \"Total Fluid Flowrate\" in the flow/component input interface, click the UOM menu button, and change \"Basis\" to \"Liq. Vol.\". As for the composition, it may be necessary to perform a manual conversion: first, convert it to xx kg/m3 based on the molecular weight, and then convert it to a mass percentage using the density of the mixture
I don’t know the density of the mixture at the corresponding temperature and pressure either
Convert ethanol and propanol to volumes based on their pure forms directly; 20 - v1 - v2 represents the volume of water
Reply to 7# yubaoru08: It’s possible to use two separate logistics routes to feed the material into the mixer, and then check the results resulting from those logistics routes
Reply to 9# elsa0918: This method should be quite accurate
