👉 Coal fluid, also known as coal tar or bitumen, is a complex mixture of hydrocarbons and other organic compounds that forms during the coalification process, where organic matter from plants is subjected to heat and pressure over millions of years. This fluid contains a variety of heavy hydrocarbons, including asphaltenes, resins, and various aromatic compounds, which can be both a byproduct and a valuable resource. Coal fluid plays a crucial role in coal mining, particularly in the extraction of bitumen through methods like steam-assisted gravity drainage (SAGD), where it is used to reduce the viscosity of bitumen, making it easier to flow and be extracted from underground reservoirs. Additionally, it has industrial applications in the production of lubricants, adhesives, and other petrochemical products.
