Crude oil is a combination of hydrocarbons that are in their almost solid to gaseous states. This natural compound is commonly found in the formation of rocks within the surface of the earth. The complex combination of organic compounds which is petroleum is made up of carbon, nitrogen, hydrogen and oxygen that may also include trace metals. This can result into a unique chemical composition producing oil-based crude oil meant for extraction.
Crude is found in wide variety of formats and locations such as semi-solids, mixed formats, liquids and heavy oils in areas of Venezuela and Canada. Crude oil must be refined first before converting it to production quality purpose for any purpose and several types of petroleum of varied levels of difficult in terms of refining.
Heavy oils can be costly to refine and extract that could lead in a longer and more complicated process. In this process, crude oil undergoes distillation to separate it into various components according to the oil’s boiling point. As a result, it can provide much easier recombination and processing.
Oil refineries can give an important source of processing the oil, refining the raw crude oil into finishing petroleum like heating oil, gasoline, petroleum gas products and kerosene. The head of the production of crude oil for end use are refineries and this would ensure that raw products can be used for the production process.
The raw crude oil should be processed before it is utilized in production. The purest form of crude known as light, sweet oil needs the least refining, utilized in its natural state for applications in various industries. The common uses of petroleum require the processing for the utilization in combustion which includes transportation fuels.
The diversity of the chemical composition of oil ensures that it can be used for processing into different end products. The molecular components can be blended into several fuels that make crude oil a very effective component in several end products where it is used.
Crude oil also comprises sulphur and this needs to be expelled from any fractions that will be burnt for it forms sulphur dioxide that can contribute to acid rain. Any fraction that will go into fuels should undergo hydrofiners in order for the sulphur to be removed.
