- Carbon-Hydrogen Ratio  & Calorific Values - A ready Reckoner - empowering field persons in plants Carbon - Hydrogen Ratio of petroleum products is of prime importance because of it provides a quick means of finding out the quality of same and suitability of use in various applications as feed to petrochemicals, fertilizer plants, energy production etc. C/H ratio as well as Calorific Value of petroleum products is dependent on specific gravity of products, a ready reckoner for field persons can be developed.  This empowers the plant operating persons since they don’t have to now depend upon the laboratory to get these values.  A simple print out pinned on information board gives immediately C/H ratio and Calorific Values only from density figure. The Carbon Hydrogen ratio in hydrocarbons is indicative of the hydrogen richness or deficiency. List of all blog articles on Petroleum QC  by RJ Patel. These properties are specifically important to Naphtha, a petroleum pr

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 information only. Lists of Android/iOs Apps developed o

- Kin. Viscosity Gasoil Excel Calculator Kin. Viscosity of petroleum products is not an additive property. Earlier on 25/03/2017,   calculation of Kin.
