Chemical characteristics of crude oil

Physical properties of Oil. Viscosity- the viscosity of an oil is a measure of the oil’s resistance to shear. Viscosity is more commonly known as resistance to flow. High viscosity implies a high resistance to flow while a low viscosity indicates a low resistance to flow. Chemically, commercial motor oil is largely a mixture of hydrocarbons — organic compounds made of hydrogen and carbon — mostly found to be straight and branched chains, though there are generally some ringed or cyclic hydrocarbons present. Crude oil composition varies somewhat according to geographic region, leading some to argue in favor of oil obtained from one area over that of another.

Properties of crude oils from Alaska North Slope: Alpine is a paraffinic crude oil with a density of 0.832 g/mL (corresponds to API° 38.4). The fresh unweathered oil  Abstract: The characterization of the crude oils is depended on the evaluation of chemical and physical properties of pure oil by-products. Characteristics of  Abstract In this paper, we explore the correlations between the effectiveness of several wax inhibitors and physico-chemical properties of crude oils. First, the  Petroleum differs in its physical and chemical characteristics from deposit to deposit. Some crude oils are extremely thick and viscous, while others are light and  Crude oil is made up of several components that have different chemical properties. Even by omitting non-hydrocarbon components, such as sulfur, nitrogen,  Physical Properties and Chemical Composition of Fuel Oil No. to develop a database on various physical-chemical properties of crude oils and petroleum.

Crude oil is made up of several components that have different chemical properties. Even by omitting non-hydrocarbon components, such as sulfur, nitrogen, oxygen, and several metals, the components that are left still may be significantly different from each other. Hydrocarbons found within crude oil range from having only 1 carbon atom to over 50. Also, there four different types of hydrocarbon molecules found, paraffins, aromatics, naphthenes, and asphaltics (olefins are not found

Crude oils are mixtures of hydrocarbon compounds ranging from smaller, volatile compounds to very large, nonvolatile compounds. The hydrocarbon structures  Abstract: Crude oils are naturally occurring liquid phase of petroleum, composed principally of hydrocarbon compounds and are extracted from the earth in the  Crude oil, liquid petroleum that is found accumulated in various porous rock crust and is extracted for burning as fuel or for processing into chemical products. Possibly the most important physical property is specific gravity (i.e., the ratio of   8 Oct 2016 Chemical properties of Petroleum Hydrocarbons are found in nature in many different forms, mainly as: Liquid Petroleum: known as “crude oil”  Download Table | Chemical characteristics of crude oils. from publication: Optimization of demulsifier formulation for separation of water from crude oil emulsions  Crude Oil Properties Overview by.

The Department of Energy Office of Fossil Energy is continuing to develop a better understanding of scientific questions associated with the production, treatment, and rail transportation of crude oils, including Bakken crude oil. To support this effort, the DOE - in collaboration with the Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) will Crude oils tend to be a mixture of paraffins-naphthenes-aromatics, with paraffins and naphthenes the predominant species. Fig. 1, although not complete, shows a distribution of crude oil samples obtained worldwide. Geochemical analyses provided the crude’s chemical nature. The Basics of Crude Oil Classification. Liquid petroleum pumped from oil wells is called “crude” or "crude oil.". Composed predominantly of carbon, crude oil contains approximately 84 to 87 percent carbon and 11 to 13 percent hydrogen. Crude oil also contains varying amounts of oxygen, sulfur, nitrogen, and helium. Many types of crude oil are produced around the world. The market value of an individual crude stream reflects its quality characteristics. 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. Petroleum refining processes are the chemical engineering processes used to transform crude oil into useful products for society. These processes are carried out in complexes called refineries, whose specific characteristics and processes depend on their location and the desired product.
