The effect of blending on selected physical properties of crude oils and their products
… The properties included kinematic viscosity, pour point, boiling point and Reid vapour pressure. The literature related to the prediction of these properties, and the changes reported to occur on blending, was critically reviewed as a preliminary to the study. The kinematic viscosity of …

A method for the rapid, accurate prediction of the physical properties of middle distillate fuels from LC-¹H NMR derived data
… number, cetane index, density, specific gravity, pour point, flash point, viscosity, filterability, heat of combustion, cloud point, volume percent aromatics, residual carbon content, and initial, 10%, 50%, 90%, and end boiling points. These property predictions have accuracies approaching the …

Characterization of palm olein (oil) as base oil for biolubricant production
… and chemical properties such as viscosity, flash point, pour point, cloud point, specific gravity, acid number, noack volatility and aniline point were analysed. The samples were degummed, neutralised and bleached to remove the red colour (carotene) and gummy materials. The bleached samples were …

Selection of Prediction Methods for Thermophysical Properties for Process Modeling and Product Design of Biodiesel Manufacturing
… namely, viscosity, cetane number, and flash point. Also, to ensure the operability of biodiesel in cold weather, one needs to quantitatively predict three low-temperature flow properties: cloud point (CP), pour point (PP), and cold filter plugging point (CFPP). This article presents the …

An Experimental Study on the Effects of Heat and Chemical Inhibitors on the Flow Behaviour of Waxy Crude Oils. The Effects of Heat and Chemical Inhibitors on the Rheological Properties of Waxy Crude Oils with regard to Pumping in Pipelines
… crude oil merely reduced the wax content and the pour point depressant reduced the gelling temperature. OSR provided a check on CSR and confirmed the gelation temperature measured. CSR provided the yield stress measured, it also provided comprehensive data that can be used for theoretical …

O ateísmo na filosofia de Pierre Bayle
… proportionées par Saint Augustin, em prenant pour point de départ l’analyse d’un extrait spécifique de l’Écriture – Luc 14;23. Bayle justifie sa critique à l’évêque de Hipona sur deux piliers: 1er) Il manifeste l’objecitf d’appuyer sa réflexion dans un panorama qui superpose les obstacles …

Determinazione delle proprietà del petrolio tramite spettroscopia 1H-NMR e analisi chemiometrica
… gravity, TBP distillation yields, KUOP factor, pour point, total acidity number and sulfur, carbon, hydrogen and nitrogen content. Successively, it was proved that also other important physical-chemical parameters can be predicted using the NMR. Among these asphaltenes, carbon residue, metal …
