Earlier following posts detailing the methodology of estimating approximate  C3 and C4 components of LPG from density@15C and RVP figures are published recently. Estimation of C3 & C4 percentage in LPG from Density & Estimation of C3 & C4 percentage in LPG from Vapor Pressure Similar Apps on Petroleum Calculations developed by RJ Patel- see here. Now an App based on above and ASTM D2598 is published. Steps : 1)  Enter Density at 15 C or/and Vapor Pressure @ 37.8C of LPG 2)  Read below  C3 and C4 with assumption of C2 and C5 impurities =1 % V. Prediction of C3 & C4 components of LPG Mobile App Prediction of  C3 - C4 Components of LPG - App as seen in  Laptop/PC You can see other Apps of LPG based on ASTM D2598 at following: An App for Calculation of Vapor pressure of Liquefied Petroleum (LP) Gases from Compositional Analysis based on ASTM D2598.    An App for Calculation of Relative Density...

The App is based on ASTM D2598 standard. This Apps covers, by compositional analysis, the approximate determination of  Motor Octane Number (MON)  of commercial propane, special-duty propane, commercial propane/butane mixtures, and commercial butane as per ASTM D2598 - Standard Practice for Calculation of Certain Physical Properties of Liquefied pet roleum (LP) Gases from Compositional Analysis. Similar Apps on Petroleum Calculations developed by RJ Patel- see here. The composition of sample of LPG is obtained by using test method D2163 or other acceptable method. From the analysis (expressed in liquid volume percent) the  Relative Density at 15.6C (60F)  of the sample may be determined.   Steps :  a) Enter the Volume % of individual components of Gas.  Ensure total % of all the gases is 100. b) Read below in last cell -  Motor Octane Number (MON)  of the sample. LPG MON APP Mobile Conversion of a composi...
