Quality and chemistry of crude oils

Journal of Environmental Quality Abstract - The effects of crude oil, leaded gasoline, kerosene, diesel fuel, and motor oil on soil the oils may have on soil dehydrogenase activity is dependent on the chemical composition of the oil itself.

Crude oil is a naturally occurring, unrefined petroleum product composed of hydrocarbon deposits and other organic materials.

Physico-chemical characteristics such as API (American Petroleum Institute gravity) specific gravity, pour point, Calorific value, Kinematic viscosities, Reid vapour pressure, Copper corrosion, Water and sediments, Total Sulphur, Distillation range (I.B.P.F.B.P., Total recovery), residue and hydrocarbon contents (saturates, aromatics and polar) of crude oils collected from different oil Quality and chemistry of crude oils Two of the most important quality characteristics are density and sulfur content. Density ranges from light to heavy, while sulfur content is characterized as sweet or sour. The crude oils represented in the chart are a selection of some of the crude oils marketed in various parts of the world. 2 Chemical and Physical Properties of Crude Oils. INTRODUCTION. Crude oil derives, by way of geological processing, from organic material initially buried in sediments at the bottom of ancient lakes and oceans.

1. Introduction. Two processes have been developed for the refining of edible oils and fats, i.e. physical and chemical refining; the decision which process to use depends on the types and qualities of the crude oil to be processed (Fig. 1).The names physical and chemical refining come from the process technology used to remove the free fatty acids (FFA) that are responsible for the oil acidity.

Consequently, to reach the maximum oil quality all the steps of the refining Alkali or chemical refining, Main groups of compounds removed, Physical Refining.

Quality of sunflower oil. The physico-chemical parameters of crude sunflower oil, refined oil obtained from the experimental unit and commercial refined oil sample is given in Table 1. The oil samples were found to be completely moisture free after refining and less than the maximum limit of 0.1 %.
