-  LPG, CNG, LNG, NGL, PNG  -  Petroleum terms understanding  There is no doubt tomorrow's energy needs will be totally derived from nature that's Solar, Wind and Hydro however, may be before this now is the time of Gas fuels for next two decades at least. Petroleum Industry has already stepped in Gas age from liquid age fuels.  CNG/LPG has taken over role of Gasoline/diesel as auto fuels.  CNG/LNG has replaced Naphtha, Diesel, Residual Fuel Oil etc in electric generating power plants and other industry as fuel replacement.  Kerosene in kitchen is being replaced by LPG which is further replaced by PNG in cities. Every day we hear petroleum terms like LPG, CNG, LNG, NGL, PNG etc and get rather confused. This post is therefore created, without using high technical terms, for layman primarily now. I am sure this will help in knowing these petroleum terms and enhance understanding of fuels better. The following table is an attempt for creating a picture in commo

- Myth - Flash point test methods are designed for kerosene contaminated with Gasoline ... part 10 of X Myth – Flash Point Petroleum test method ASTM D56, ASTM D93, IP 170 etc are prepared for Kerosene samples contaminated with Volatile products like gasoline or Naphtha. Facts – False.   Standard test methods ASTM D56, ASTM D93, IP 170 etc are prepared for Kerosene samples which are not contaminated with Gasoline/Naphtha.   A round robin testing of Kerosene samples mixed with 1 % gasoline was programmed at 6 of petroleum testing labs..... tabulate results show vast difference among the labs, beyond the precision limits of test method. -          Explanation follows Keywords - Kerosene contaminated with Gasoline, ASTM D56, ASTM D93, IP 170,  Naphtha Author's Profile https://twitter.com/rjpatel13?lang=en

- Myth of drop in Kerosene flash point is by 1 deg C per percentage of Gasoline contamination ..Part 9  of  X Myth - Due to contamination of Kerosene with gasoline, drop in flash point is by 1 deg C per percentage of Gasoline contamination. Fact - Usually not true, Drop in Kerosene flash point due to per percentage Gasoline or Naphtha contamination varies from 1 deg C, on lower side to about 10 deg C on maximum side.   Rarely drop of 1 deg C is noticed per percentage contamination,  this is only true if Gasoline or Naphtha is highly weathered or while lab experimenting, gasoline blend not properly prepared, or the sample is mishandled.

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 Gasolin
