An App for Calculation of Vapor pressure of Liquefied Petroleum (LP) Gases from Compositional Analysis based on D2598

-

The App is based on ASTM D2598 standard.


This Apps covers, by compositional analysis, the approximate determination of Vapor pressure 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 petroleum (LP) Gases from Compositional Analysis.

Apps developed on other Petroleum Calculations - 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 vapor pressure at 37.8 C 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 - Vapor pressure of the sample.
Vapor pressure App - ASTM D2598

Conversion of a compositional analysis from mole, gas volume or weight basis to liquid volume can be obtained by using ASTM D2421 or other suitable method.

Vapor pressure is an important specification of commercial propane, special duty propane, propane/butane mixtures and commercial butane that assure adequate vaporisation, safety and compatibility with commercial appliances.
App as seen in Laptop/PC.

Report the vapor pressure value calculated after rounding to the nearest multiple of 7 kPa g as LP-gas vapor pressure of the sample, kPa gage at 37.8°C (100°F).

- 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.

Density conversion to any temperature say 20 C, 15 C or any desired temperature from any observed temp Some of the countries like Russian block follow standard temperature 20 deg C as compared to Commonwealth countries which have standard temperature 15 deg C.  The calculator developed for conversion of Density from observed temperature to 20C or 15C or any desired temperature is thus very handy.   It may be noted that the calculator is for finished petroleum products and uses ASTM tables 1952 version for this conversion. For Excel Worksheet you may contact by email to  rjpatelioc2014@gmail.com and specify your clear requirement as per the title of this post.

Lists of Android/iOs Apps developed on Petroleum Calculation - see here.      (These apps convert 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.) One follower from Kiev, Ukraine  has requested the formula for the subject conversion. The post gives a simple way to convert Density of petroleum products from ambient temperature  ( say 15 +/-7  deg C  )  to density at 15 Deg C, in line with ASTM table 53B,  without using these table and in the field with simple calculation. See my earlier post dated 18 Dec 2016, for detail description of the procedure explained there.
