petroleum classification
Petroleum is an important resource in modern society, playing an important role both in industry and in our daily lives. Petroleum is a mixture of liquid, solid and gaseous hydrocarbons. When it is heated to different temperatures, it produces different substances. Heating oil is closely related to our heat exchanger.
Chemical composition
Crude oil is a mixture of hydrocarbons that vary in size and complexity, from small, simple molecules to large, complex compounds. Crude oil can be divided into three broad categories based on hydrocarbon content: light, medium and heavy. Light crude oil has low density and low viscosity, while heavy crude oil has high density and high viscosity. Mid-cap crude oil is somewhere in between.
Where it comes from
Offshore oil is oil extracted from the ocean floor, while onshore oil comes from land-based sources. The geological formations in which oil is found also play an important role in petroleum classification. For example, shale oil is petroleum extracted from kerogen in shale rock formations, while tight oil comes from low-permeability reservoirs.
How it is processed
Conventional oil extracted using standard drilling techniques may require additional processes, such as distillation and refining, to make it usable for various purposes. In contrast, unconventional oil, such as oil sands or oil shale, requires expensive and time-consuming techniques to extract and refine.
Properties
Different types of oil have specific uses based on their properties. For example, light crude oil is ideal for producing gasoline, while heavy crude oil is better suited for the production of diesel, lubricants, and asphalt. Understanding these differences and matching oil types to their intended uses is critical to meeting the energy needs of modern society.
