How is heavy crude oil refined

The economic unattractiveness of heavy crude oils in the global oil market scene is fast changing due to the looming scarcity of light oils. There are huge  18 Dec 2019 Heavy crude oil refining. The processing of heavy oils in refineries, especially in the existing refineries, presents many difficulties due to their 

Before the actual refining begins, the stored heavy crude oil is cleaned of contaminants such as sand and water. Once completed, this clean crude feedstock is heated first by piping it close to, but separated from, the much hotter already-refined product (this is a "heat exchange"); then secondly by piping through a furnace which heats the crude oil even more. In the refining process, crude oil is refined to produce different petroleum products like gasoline, diesel, and jet fuel. For the conversion to take place, crude oil is heated and introduced into the distillation tower. In the tower, oil is broken down into various petroleum products. Specifications for producing this type of crude include a gravity target range of around 20°-25° API and a target sulphur content of around 3-4 wt%. There is currently high demand for this quality crude oil because the production of Maya and other similar heavy crude oils has been declining in recent years. Refineries take a nearly useless hazardous material – crude oil, the unprocessed stuff that comes out of the ground – and turn it into valuable refined products like gasoline, diesel and jet fuel, petrochemicals, and other materials, including the Styrofoam cup your java comes in. Heavy crude oil (or extra heavy crude oil) is highly-viscous oil that cannot easily flow to production wells under normal reservoir conditions. It is referred to as "heavy" because its density or specific gravity is higher than that of light crude oil. Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°. For heavy oil to be made into gasoline, it has to be refined, cracked to make large hydrocarbons smaller, and treated to remove contaminants like sulfur. All of this extra refining requires more energy input for the same energy output, which reduces the energy returned on energy invested (EROEI) ratio. Generally, the less processing or refining a crude oil undergoes, the more valuable it is considered. Price differentials between crude oils typically reflect the ease of refining. Crude oil can be refined to create products ranging from asphalt and gasoline to lighter fluids and natural gas,

Crude oil is unrefined liquid petroleum. which is breaking down large molecules of heavy oils; reforming, which is changing molecular structures of low -quality 

23 Sep 2019 Heavier liquids, called gas oils, separate lower down in the distillation tower, while the heaviest fractions with the highest boiling points settle at  Heavy crude oil has more negative impact on the environment than its light counterpart since its refinement requires the use of more advanced techniques an the  For heavy oil to be made into gasoline, it has to be refined, cracked to make large hydrocarbons smaller, and treated to remove contaminants like sulfur. This difference is the result of the refining process, which takes the heavy, crude oil from the ground and processes it into petroleum products like gasoline,  Crude oil naturally contains contaminants such as sulfur, nitrogen, and heavy refining process is blending various streams into finished petroleum products.

The designation of sweet or sour may seem a bit unusual, but in the days when crude oil was sought after primarily as lamp oil, petroleum producers realized that

30 Jan 2018 Most grades have an API gravity between 10 and 70. Heavier grades of crude are generally less expensive but are more difficult to refine, 

The heavier components can be refined into heavy fuel oils or even asphalt, or they can be “split” using a more extensive refining process into lighter petroleum   Energy – heavy oils require much more energy to produce and refine than light crude oil. This leads to higher overall greenhouse gas emissions per barrel of oil   Geopolitical concerns and seasonal demand bolstered crude oil prices in January Refining margins have recently been at all-time highs, but the industry faces  25 Feb 2020 crude oil production with relatively heavy crude oil imports, the United States has significantly increased its ability to export refined product. heavy crude oils found and produced throughout the world. While all sources of crude oil have different properties, all ot the final refined transportation products. Crude oils that contain appreciable quantities of hydrogen sulfide or other reactive sulfur compounds are called "sour." Those with less sulfur are called " sweet." 

For heavy oil to be made into gasoline, it has to be refined, cracked to make large hydrocarbons smaller, and treated to remove contaminants like sulfur.

The oil refining process starts with a fractional distillation column. Heavy gas or Fuel oil - used for industrial fuel; starting material for making other products.
