Petroleum Products QC

A practical situation like designing of pipeline, pumps etc in oil industry require the density of petroleum products at the likely temperature  at which the products will flow. Thus the exercise is when the density is taken at observed temperature say 19 deg C and the what will be the converted density at say 27 deg C? The answer is provided in a single step, in the app developed here. Similar Apps on Petroleum Calculations developed by RJ Patel- see here.   Earlier,  various Density conversion Apps and procedures are blogged for petroleum products and crude Oil.  Here now, an app is presented for density conversion from observed temperature to any desired temperature say 15 C or 20 C or 27 C or  any temperature T. The conversion uses relationships from ASTM 53b tables for petroleum products.  You can obtain this app by writing to rjpatelioc2014@gmail.com. Author's Profile  clik here.             ...

This App for calculated Cetane Index by Four Variable Equation  provides a means for estimating the ASTM cetane number  (Test Method D613) of distillate fuels from density and  distillation recovery temperature measurements. The value  computed from the equation is termed the Calculated Cetane  Index by Four Variable Equation. Similar Apps on Petroleum Calculations developed by RJ Patel- see here. Procedure B   is to be used for Specification ASTM D975, Grade No. 2–D S500. For Procedure A please click here. CCI as per ASTM D4737 Procedure B Centigrade BP The Calculated Cetane Index by Four Variable Equation  is not an optional method for expressing ASTM cetane number.  It is a supplementary tool for estimating cetane number when  a result by Test Method D613 is not available and if cetane  improver is not used. As a supplementary tool, the Calculated  Cetane Index by Four Variable equation must be used with ...

This App is based on ASTM D976, covers the Calculated Cetane Index which directly estimates the ASTM Cetane Number of distillate fuels from API Gravity and mid boiling point. Second part of the App which has density at 15 C, (gm/mL) and mid boiling point in deg C. Similar Apps on Petroleum Calculations developed by RJ Patel- see here. CCI API Gravity & Mid Boiling Point F CCI Density 15C and Mid Boiling Point C The Calculated Cetane Index is not an optional method for expressing ASTM cetane number. It is a supplementary tool to estimate cetane number when used with due regard for its limitations. The Calculated Cetane Index formula is particularly applicable to straight-run fuels, catalytically cracked stocks, and blends of the two. Test Method D4737 is the preferred method as estimator of cetane number and a separate App has been created based on this four variable CCI method. The Calculated Cetane Index is one tool available for estimating ASTM c...
