Scope: This International Standard specifies a method for the determination of the bromine number of the following materials: a) petroleum distillates that are substantially free of material lighter than 2-methylpropane, and that have 90 %(V/V) (i.e.…
The hydrodynamic parameters of molecular distillation (mean free pathMFP and Knudsen numberKn) were estimated under a screening of evaporator temperature (423.15-623.15 K) and the pressure system (0.1-1.0 Pa). The modeling and simulation were based…
The present research was purposed to estimate the heat of vaporization for petroleum fractions and pure hydrocarbons by the lease square support vector machine (LSSVM) as a function of the specific gravity, molecular weight, and boiling point…
Understanding the molecular compositions of petroleum light fractions plays an important role in realizing molecule management of petroleum refining processes. The Research Institute of Petroleum Processing (RIPP) has established various methods to…
1 Scope This document specifies a test method for the determination of the content of mono-aromatic, di-aromatic and tri+-aromatic hydrocarbons in diesel fuels, paraffinic diesel fuels and petroleum distillates. This document defines two procedures,…
Abstract: The influence of ozonization on the composition and flotation properties of petroleum and petroleum distillate fractions is considered. Preliminary ozonization is found to promote the formation of apolar hydrocarbon collectors of various…
Conversion of olefin-rich side streams of petroleum distillate cracking operations, pyrolysis gasoline (pygas), to hydrocarbon resins (HRs) represents a promising technology to upgrade the pygas byproduct and facilitate pygas valorization. Several…

The precise chromatographic isolation of saturates is a common problem of the characterization of highly paraffinic petroleum based samples. Incomplete elution of high-molecular-weight saturates (HMWS) or contamination of saturates by aromatics can…
In this work, an atmospheric petroleum residue was fractionated using a falling film molecular distillation pilot plant with molecular distillation temperatures ranging from 190 to 320 C. The process produced four distillate cuts and four residues…
Petroleum residues with varying cutting depth and corresponding vacuum distillates have been prepared from laboratory deep-vacuum fractionation using unconventional heavy oil (UHO) originated from Venezuela first. They are then sequentially…
Abstract Low field nuclear magnetic resonance (LF-NMR) has several applications in the oilfield industry such as in predicting the viscosity and evaluating porosity, permeability, fluid saturation of reservoir rocks, and the water content in fluids.…
Petroleum and distillates contain different concentrations of aromatic hydrocarbons. These compounds are important downstream as process indicators for product formulation. They can reduce the calorific value of some distillates, poison catalysts, be…
