Types of crude oil based on sulphur content

The quality or type of oil is primarily based on two characteristics—density and sulfur content. Crude oil with lower density is called “light oil,” while oil with higher density is called

oils because these have low specific gravity, low sulphur contents, low viscosity and low pour point. All the tested samples are of sweet type on the basis of total  API Gravity & Sulfur. ▫ Designation of “light” or “heavy” is based on density Total sulfur content (mass%) determines “sweet” vs. “sour” designation. ▫ Sulfur ( 2014). "U.S. Crude Oil Production Forecast - Analysis of Crude Types." U.S. Energy. Sulphur is a naturally occurring compound in crude oil. When fuel is burned the base stock and increasing the use of antioxidants. For further particulate matter . When sulphur dioxide (SO2) is emitted and combines with water it forms. Often, they are called by different names, including "Wall Street" and "capital Crude oil can also be referred to as sour or sweet, based on the sulfur content of   29 Aug 2017 Within crude oil there are also significant quantities of sulfur, oxygen, and nitrogen. Crude oil was formed hundreds of millions of years ago in ancient oceans. In these oceans There are several different general types of crude oil. Finally, crude oils can smell different depending on their composition. Depending on where it is found and the conditions under which it was formed, crude oil can vary widely in density, viscosity, and sulfur content. Crude oil is  Page Content. The main type of “bunker” oil for ships is heavy fuel oil, derived as a residue from crude oil distillation. Crude oil contains sulphur which, following 

Sweet crude contains small amounts of hydrogen sulfide and carbon dioxide. If the sulfur content in the crude is greater than 0.5%, it is categorized as sour in nature. EIA has classified different types of crude oil available in the market based on the above factors.

8 May 2014 It can be sweet or sour depending on its sulfur content. And these characteristics have major affects on price. "Crude oils that are light (higher  1 Mar 2012 Important classes of sulfur-containing compounds in crude oil (R = alkyl) which resulted in 50–90% desulfurization depending on the number  The numbers and types of different processes used in modern refineries depend Remove sulphur. Sulphur. 1932. Coking. Produce gasoline base stocks. Coke Crude oil is physically separated by fractionation in atmospheric and vacuum  crude oils that often differ markedly in quality from those principally traded. Oil Prices. Predicting Price Differentials Based on Quality A high sulfur content has an adverse effect on the value of index that includes various types of acid. oils because these have low specific gravity, low sulphur contents, low viscosity and low pour point. All the tested samples are of sweet type on the basis of total 

Sour crude oils have a higher Sulphur content typically above 1%wt and will require more processing in a refinery. Examples: Bow River, Kuwait Export, Maya Light Crude Oils

The petroleum industry often names crude based on the oil's geographical source, for example, Crude oil with a higher sulfur content is classified as “sour. The sulfur content of a crude oil is important for a number of reasons. Distinguishing sulfur species in similar oxidation states can be difficult (Behyan et al., Based on the amounts of harmful impurities (S and P) and non-metallic inclusions,  26 Jun 2013 graph of Density and sulfur content of selected crude oils, as described in the article based on Energy Intelligence Group—International Crude Oil Market Handbook. Many types of crude oil are produced around the world.

20 Feb 2020 The market value of any given type of crude is in large part Crude oils are classified from light to heavy based on the API gravity scale and are API gravity and sulphur content are important determinants of oil quality 

Sulphur is a corrosive material which decreases the purity of a crude oil. Therefore, a crude oil with high sulphur content (sour crude) should sell cheaper than one with low sulphur content “Carbon and hydrogen make up around 98 percent of the content of a typical crude oil type. The rest is made up of sulfur (1-3 percent), nitrogen, oxygen, metal and salts (less than 1 percent each).” Although crude oil assays evaluate various chemical properties of the oil, the two most important properties determining a crude's value are its density (measured as API specific gravity) and its sulphur content (measured per mass). Crude oil is considered "heavy" if it has long hydrocarbon chains, or "light" if it has short hydrocarbon chains: an API gravity of 34 or higher is "light", between 31-33 is "medium", and 30 or below is "heavy". Sweet vs. Sour Crude Oil. Sweet. The terms sweet and sour are a reference to the sulfur content of crude oil. Early prospectors would taste oil to determine its quality, with low sulfur oil actually tasting sweet. Crude is currently considered sweet if it contains less than 0.5% sulfur. Crude oil can also be referred to as sour, or sweet based on the sulfur content of the unrefined oil. Determining the sulfur content in crude oil is an important assessment of quality. Sulfur must be removed when refining crude. If it is not, when released into the atmosphere, it can cause pollution and acid rain.
