Wax appearance temperature (WAT) is an important parameter of petroleum fluids. Obtaining accurate wax appearance temperature is a prerequisite for ensuring the safe transportation of waxy crude oil pipelines. New measurement methods were proposed in…
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,…
We present a direct method for evaluating the effectiveness of inhibitors on asphaltene deposition from crude oil based on a Kretschmann configuration surface plasmon resonance (SPR) sensor. We demonstrate that shifts in the peak SPR wavelength…
Two best-known molecular type analyses are PNA and SAP methods, which divide an olefin-free fraction into the sub-fractions (Paraffins, Naphthenes, and Aromatics) and (Saturates, Aromatics, and Poly-nuclear aromatics), respectively. In this study, a…
Identification of hydrocarbons and crude oils is typically carried out with samples that, taken from natural sources or refineries, must be brought to the laboratory for their analysis with rather sophisticated instruments. Alternatively, “in situ”…
