An App for Prediction of C3 and C4 components of LPG from its density and RVP based on ASTM D2598

-
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.

- Excel Formula-Density Conversion to 15 deg C,  table ASTM 53 B - 1980,    Excel sheet giving the Density 15 deg C figures from given observed Density and observed temperature for petroleum product as derived from ASTM tables 53 B. Density conversion to 15 deg C matches exactly with the ASTM conversion tables 1980. Lists of Android/iOs Apps developed on Petroleum Calculation - see here.      (These apps convert Density/API gravity exactly as per ASTM tables 5a, 5b, 6a, 6b, 23a,23b, 24a,24b, 53a,53b, 54a,54b to standard temperature 15 C,  20 C and 60 F.)   Example:  Observed density is 792 kg/Cu. M and observed temperature is 29 deg C. Corresponding 15 deg C for this set of data comes 802.2  kg/Cu. M Excel Worksheet - green color cells  observed density and observed sample temperature are variables and Red color digits are the answer - density at 15 deg C.  Apps developed on Petroleum Calculations - see here. ...

Crude Oil Density conversion to 15 C from observed temperature as per ASTM 53A  and volume Correction as per Petroleum tables ASTM 54A using an App developed. The App developed converts a) Density at 15 Deg C from observed density and temperature and b) calculates the bulk volume from natural to volume at 15 deg C, US barrels at 60 deg F and weight in MT. Large volume of crude moves from production to user refineries globally. Oil Industry uses ASTM tables published by API/IP/ASTM  to account Oil quantity on board of the tankers for calculating quantity.  Following publication is in IS system where mass is in Kg, volume is in Kg/Cu.M and temperature is in Centigrade and followed most of Europe, Asia, Africa & Commonwealth countries with standard temperature as 15 deg C. It may be noted that the above tables ASTM 53 A and 54 A are for Crude oil and not for refined petroleum products for which there are different ASTM tables for Corrections. See different...
