Api of crude oil classification
The service rating of passenger car and commercial automotive motor oils is classified by the American Petroleum Institute (API). The program certifies that API Gravity: An inverse ratio of the density of oil to a relative density (i.e., water). It is determined by centrifugal or extraction testing and is used for oil classification. Heavy Crude Oil: Defined as having API gravity below 22.3 degrees API. 26 Mar 2018 Predicting pressure volume temperature properties of black oil is one of have used API gravity, which is used to classify crude oils, to develop Crude oil testing and assay services provided by Intertek support customers from the well-head to the refinery across the world. Each crude oil reservoir and The Authors gratefully acknowledge the American Petroleum Institute (API) for providing Oil Classification Categories as Defined by 33 US CFR, Section
A crude oil will typically have an API between 15 and 45 degrees. Higher API indicates a lighter (lower density) crude. Lower API indicates a heavier (more dense)
Crude's classification as either “light” or “heavy” depends on the oil’s relative density, based on the American Petroleum Institute (API) Gravity. This measurement reflects how light or heavy a crude oil is compared to water. If an oil’s API Gravity is greater than 10, it is lighter than water and will float on it. API Gravity is the oil industry standard used to determine and classify the density of oil. Density is an integral part of determining the value of oil, where light oils command a higher price due to the ease with which they are converted to gasoline. Types of Crude By API Gravity. When crude oil is classified based on its API gravity it is divided into one of the following four classifications: Light – Light crude oil has an API gravity of 31.1 °API or higher. Medium – Medium crude oil has an API gravity that ranges between 22.3 °API and 31.1 °API. Crude can be classified as “light” or “heavy,” a characteristic which refers to the oil’s relative density based on the American Petroleum Institute (API) Gravity. This measurement reflects how light or heavy a crude oil is compared to water. If an oil’s API Gravity is greater than 10, it is lighter than water and will float on it. In the Engine Oil Licensing & Certification System (EOLCS) Categories and Classifications section you can find detailed information on American Petroleum’s current, latest and obsolete oil specifications. The documents section is a public publication registry of the EOLCS program updates and program guidelines. 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.

Generally speaking, oil with an API gravity between 40 and 45° commands the highest prices. Above 45°, the molecular chains become shorter and less valuable to refineries. Crude oil is classified as light, medium, or heavy according to its measured API gravity. Light crude oil has an API gravity higher than 31.1° (i.e., less than 870 kg/m 3) Any oils with API gravity of 45 or over have shorter molecular chains which are less desirable to refineries. Below is an overview of the four major crude oil classifications: Light crude oil; Any crude oil with API gravity of over 31.1 degrees falls into the light crude oil category. Medium crude oil The API Manual of Petroleum Measurement Standards (MPMS) is the authoritative document on crude measurement for measurement professionals. The document outlines the important elements throughout the process of moving crude oil from the wellhead to the refinery.
The American Petroleum Institute (API) is the only national trade association that represents all aspects of America’s oil and natural gas industry. Our more than 600 corporate members, from the largest major oil company to the smallest of independents, come from all segments of the industry.
Automobile manufacturers recommend oils that carry the API Certification. Mark. See the ILSAC STANDARD FOR PASSENGER CAR ENGINE. OILS chart on the
14 May 2014 demonstrating that Bakken crude oil is properly classified as a API gravity varies inversely with specific gravity so that increasing API.
The API gravity is nothing more than the standard specific gravity used by the oil industry, which compares the density of oil to that of water through a calculation A crude oil will typically have an API between 15 and 45 degrees. Higher API indicates a lighter (lower density) crude. Lower API indicates a heavier (more dense) Crude's classification as either “light” or “heavy” depends on the oil's relative density, based on the American Petroleum Institute (API) Gravity. This measurement
17 Feb 2011 The different types of crude oil are classified based on the American Petroleum Gravity (API) gravity and viscosity. The properties may vary in 16 Oct 2018 API gravity the samples were classified as light (API30), medium (API23) and heavy (API16) crude oils [25]. Note that, as expected [1], density 19 Apr 2017 The higher the API gravity, the lower the density of the petroleum liquid, so light oils have high API gravities. Based on the mix of their respective 8 Feb 2015 Barrels of crude oil per metric ton = 1 / [141.5 / (API gravity + 131.5) x 0.159]. API gravity classifications and grades. In general oils with API oil on the basis of API gravity except one (N) sample which belongs to the medium class. Key words: Classification, quality, sweet, sour, saturates, aromatics, refers to crude oils having API gravity lower than 22 degrees.
