Crude oil classification ppt

Crude oil or petroleum production occurs to varying degrees in association with some natural gas. In the reservoir, gas may exist entirely in solution with the oil, above the bubble point pressure. If the oil is saturated, a gas cap may be present above the oil. During production, fluid pressure drops, and at some point, it will fall below

Presentation. On. CRUDE OIL CHARACTERISTICS Petroleum/Crude oil. Natural occurring hydrocarbon found below the surface of the earth. Crude Oil means all kinds of hydrocarbons in liquid form in their natural state or obtained by Natural Gas by condensation or extraction. § Heavy Oil, Extra Heavy Oil, Oil Sands, Tar Sands, Bitumen, …. Ł need for a simple classification 4 Classes based mainly on downhole viscosity : 0A Class : Medium Heavy Oil 25°> d°API > 18° 100 cPo >m > 10 cPo, mobile at reservoir conditions 0B Class : Extra Heavy Oil 20°> d°API > 7° 10 000 cPo >m > 100 cPo , mobile at reservoir Powerpoint presentation on crude oil, how it is created, fractional distillation, hydrocarbons, combustion, alkenes, global warming and acid rain. Crude oil with low content of sulfur means 'sweet' and the presence of high content sulfur is known as 'sour'. One of the largest and major Classifications of Crude oil is Brent Blend, which is found in the North Sea. With an API gravity of 38.3 degrees and 0.37% of sulfur, this blend of crude oil comes from 15 various oil fields in the North Sea. Crude oil or petroleum production occurs to varying degrees in association with some natural gas. In the reservoir, gas may exist entirely in solution with the oil, above the bubble point pressure.

There objective is to separate the mixture into several fractions like naphtha, kerosene, diesel and gas oil. A schematic diagram of an atmospheric crude fractionation unit is shown in Figure 1-1.

MARGOSCHES : CLASSIFICATION OF CRUDE OILS. 3 oils from the producing fields throughout the world fell definitely in one of the three classes : paraffin, intermediate, or naphthene base. Nelson 23 gives a list of methods for judging the base of an oil. Apart from considering the properties indicated in the reports by N. A. C. Smith,17

24 Oct 2011 Exhibit 4 lists some important crude oils in the world oil trade and indicates the API gravity/sulfur classification for each of these crudes. Classifications of Crude Oil. 1.  2.1 Introduction  2.2 Classification Systems 2.2.1 Classification as a Hydrocarbon Resource 2.2.2 Classification by Chemical Composition 2.2.3 Correlation Index 2.2.4 Density 2.2.5 API Gravity 2.2.6 Viscosity 2.2.7 Carbon Distribution 2.2.8 Viscosity–Gravity Constant 2.2.9 UOP Characterization Composition and Classification of Crude Oils Crude oil is a complex liquid mixture made up of a vast number of hydrocarbon compounds that consist mainly of carbon and hydrogen in differing proportions. Composition of Crude Oil The first type of classification is concerned with the quantities of the varioushydrocarbons present in a crude and their physical properties, such as viscosityand boiling point. Table: Classification of Crude Oils Classificatory schemes of interest to geologists are concerned with the molecular structures of oils because these may be keys to their source and geological history.It classifies oils into paraffinic, naphthenic, and intermediate types according to their Napthenes: Make up 30 to 60% of crude Have a carbon to hydrogen ratio of 1:2. These are cyclic compounds/cycloparaffins. They are higher in density than equivalent paraffins and are more viscous. 3.Aromatics: Make up 3 to 30% of crude. Undesirable because burning them results in soot. Much less hydrogen in Petroleum/Crude oil. Natural occurring hydrocarbon found below the surface of the earth. Crude Oil means all kinds of hydrocarbons in liquid form in their natural state or obtained by Natural Gas by condensation or extraction.

After decades of decline, crude oil production in the United States has recently been From 2003 through 2007 crude oil prices more than doubled from their historical Distillate or distillate fuel oil is a general classification for the petroleum  Crude oil formed at depth in a sedimentary basin migrates upward because of lower density. Many such migrations end with the oil collecting beneath a layer of   20 Mar 2019 and the Severity of Crude Oil Transportation. Incidents? particularly crude oil and ethanol, by rail.

Characteristics of Crude Oil •The hydrocarbons in crude oil can generally be divided into four categories: •Paraffins: These can make up 15 to 60% of crude. •Paraffins are the desired content in crude and what are used to make fuels. •The shorter the paraffins are, the lighter the crude is.

Physical and Chemical Properties of Crude Oil and Oil Products 1- Density, Specific Gravity, and API Gravity Density is defined as mass per unit volume of a fluid. Density is a state function and for a pure compound depends on both temperature and pressure and is shown by ρ. Liquid One of the largest and major Classifications of Crude oil is Brent Blend, which is found in the North Sea. With an API gravity of 38.3 degrees and 0.37% of sulfur, this blend of crude oil comes from 15 various oil fields in the North Sea. West Texas Intermediate (WTI) otherwise known as Texas Light Sweet, 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. Composition and Classification of Crude Oils Crude oil is a complex liquid mixture made up of a vast number of hydrocarbon compounds that consist mainly of carbon and hydrogen in differing proportions. In addition, small amounts of organic compounds containing sulfur, oxygen, nitrogen and metals such as
