Aviation fuels - Test classification remembering

Oil industry in India stipulate various classification of group of tests naming Alphabetically like Test A, Test B etc. These are defined in Aviation product Quality Control Manual (AQCAM) at various stages of product manufacturing to Aircraft refuelling.

An easy way to remember various alphabetical tests associated to respective stages are tabulated below which field officers handling product will find very useful.

Above may be useful as training material.

- Temperature around 3 deg C, - Density Conversion for Petroleum Products from observed temperature to 15 C without use of ASTM Table (1980 series)

-
One follower from Alaska, US has requested the formula for the subject conversion. The post gives a simple way to convert Density of petroleum products from ambient temperature  ( around 3 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,  China and southern hemisphere New Zealand,  Southern Australia etc  where winter temperature is very low, this method is useful. A)    Simplified   Formula           D 15  = d o  - 10 +  C  x (   t o  – T)    Density at 15 deg c   = Density observed  - 10 + Constant x ( temp observed – T  )    Temperature unit is  C  ...

RVP Vs TVP of Gasoline

Is Reid Vapor pressure of gasoline (RVP) is same as true vapor pressure (TVP) ? What is difference between RVP and TVP value ? The blog article explain difference between RVP and TVP at slight higher technical level than common man perspectives. List of all blog articles on Petroleum QC  by RJ Patel. Reid vapor pressure  is a common measure of the  volatility of gasoline . It is defined as the absolute  vapor pressure  exerted by a liquid at 37.8 °C (100 °F) as determined by the test method ASTM-D-323. The test method measures the vapor pressure of gasoline, volatile crude oil, and other volatile petroleum products, except for  liquefied petroleum gases . RVP is stated in kilopascals and represents a relative pressure to the atmospheric pressure because ASTM-D-323 measures the gauge pressure of the sample in a non-evacuated chamber. All values are in SI units and are regarded as standards. Imperial units are for informat...

- Relationship between Flash Point and Front-end Distillation data of petroleum products, (a Scholarly article)

-
- Relationship between Flash Point and Front-end Distillation data of petroleum products,  The relationship between Flash Point and Atmospheric front-end Distillation data of petroleum products, normally recorded during the routine testing are correlated during 1986 – 1988 period by a team (S/S  RJ Patel, PD Dusane, NS Kamble, SK Shukla at IOC Kandla Laboratory ).  The idea was originated from similar literature that time, W.L. Nelson ( Petroleum Engineering, pg 131, edition 1982, initially put forward in year 1944). Team under the leadership of the author of this blog could work out a most improved/accurate empirical relationship as given below: Predicted Abel Flash Point  FP = 0.613*IBP + 0.193*T 10   -  84.0 .              ( all temperatures  in deg Centigrade, C ). Where,    FP = Abel Flash Point deg, C                 IBP= Initial Boili...

Petroleum Products API Gravity conversion to 60F from observed temperature as per ASTM 5B  and volume Correction VCF as per Petroleum tables ASTM 6B using an App developed. Scrolling Down The App developed converts a) API Gravity at 60 Deg F from observed API Gravity and temperature and b) calculates the bulk volume from natural to volume at 60 deg F, US barrels at 60 deg F, US Gallons at 60F for Petroleum Products. Large volume of petroleum products moves from production to user refineries globally. Oil Industry uses ASTM tables published by API/IP/ASTM  to account Oil quantity on board of the tankers for calculating quantity. It may be noted that this App is using tables ASTM 5B and 6B,  for Petroleum Products and not for Crude Oil for which there are different ASTM tables for Corrections. See different Apps suiting this. US, Canada, Persian Gulf, etc where  FPS system   with API Gravity, US Barrels, and Deg F is more prevalent Standa...
