- Patel's Density Conversion for Liquefied Petroleum Gas (LPG)  from observed temperature to 15 C without use of  ASTM Table.  (Density unit Kg/L).   A separate post for the density unit Kg/M3 is given here.  An exact conversion in Android /iOS App is given at the end of this article. Following simple method help in easily converting LPG density to 15 deg C, without using ASTM Tables, and without help of calculators. It is very handy for field persons who are taking density for comparing parent density for Quality Control purpose.  LPG is transported in pipeline or marine tankers in cryogenic conditions and usually sample temperature is around 02 -15 deg C. Secondly, as per request from one of the users, LPG density units used here is Kg/L.   ( 1000 Kg/L = 1 Kg/m3).  Two different alternate simplified ways are prescribed here. User may find their own alternative. Option 1.    For LPG.  (Density range ...

- 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. ...

- Flash Point Prediction - Petroleum Products Blending - Calculation formula and table How to predict Flash point of resultant product after blending two stocks ?  or  how to get volume required of products to get desired  blended product Flash Point ? Many times flash point improvement is desired by blending higher flash petroleum product to lower Flash Point Product at Petroleum storage depots. List of all blog articles on Petroleum QC  by RJ Patel. Following table and formula can be used to predict the desirable variable figure of  volume of product or flash point.   In the table below against Flash Point Deg C some constant number " A " is listed in next column.

Jet A-1 Density conversion to 15 C from observed temperature without ASTM tables

-
Jet A-1 Density conversion to 15 C from observed temperature without ASTM tables  Globally Oil industry Quality Manuals specify certain tolerance density variation for petroleum products like Gasoline, Diesel fuels, Aviation fuels etc, between density of dispatched products and density of received product. As long as this density difference remains less than permitted variation, the product is accepted in the system. List of all blog articles on Petroleum QC  by RJ Patel. In India, for Aviation products, this quality control variation in density number is +/- 2.5 kg/m 3  against JIG specified variation +/- 3.0 kg/m 3 maximum. During Aviation products transfer from one place to another using Ocean tanker, pipeline, Rail T/Ws, Road Tank Truck etc. Density at 15 deg C is recorded at despatch and receipt end.  A simple way of converting observed density from ambient temperature to 15 deg C has been developed, without ASTM tables , using simple ...
