- Myth Gasoline rises to the top of the storage tank from Kerosene contaminated with Gasoline .. Part 8 of X

-
Myth - In a Kerosene storage tank,  if  Kerosene is mixed/ contaminated with gasoline, Gasoline will always rise to the top of the storage tank above Kerosene layer

Fact - In a Kerosene storage  tank, if kerosene is mixed / Contaminated with gasoline, Gasoline will not always rise to the storage tank above Kerosene layer. 

 In number of incidents, it is noticed that the contaminated Gasoline remain trapped in a particular layer in storage tank, based on density of layer.  It happens when top layer of Kerosene is lighter ( lower density) than the lower layer which is having higher density comparatively to the top layer despite containing some percentage of lighter Gasoline. 

It is also observed that such gasoline containing layer remains trapped below the top layer indefinitely unless disturbed by effective product circulation  or product pumping out or in for dilution etc.

 Just for novice, typical 15 deg C Density of Kerosene is around 780-810 Kg/Cu. M  and that of Gasoline is 730-760 Kg/Cu. M.

 Rear life examples follow shortly.

- 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.

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.

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.
