- Flash Point- Density blending Calculator

Density is an additive property while Flash Point is a non-additive Property.

When two different batches are mixed,  usually this is the case when a new batch of products received in a tank having already some of the remaining product of earlier batch.

The calculator is very handy to predict the likely flash point of commingled / mixed product. 

Also, this can be used to know the quantity of new batch to be blended/required to get the desired flash point when the earlier product is having undesired flash point. 

Industry has to manage many products batches having slightly less than the specification flash point, resulted due to small contamination of volatile product like naphtha, gasoline etc in Kerosene, Jet fuel, diesel fuel etc.  Example is given in the second image below:

Flash point Calculator may not give correct blend value if one of the products has significant contamination of volatile hydrocarbons,  resulting into heterogeneous mixture.

- 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. ...

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. For areas in Norther Europe,  Canada,  Russia,...

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.
