Process of extracting petrol from crude oil
This helps to extract oil and gasoline for commercial use. Thermal Depolymerization (TDP): The process starts with hydrous pyrolysis, which involves the heating of organic compounds at a high temperature (in the presence of water). This helps in reducing complex organic materials, such as biomass, into light crude oil. Drilling and Extraction. Once a potential oil deposit is located, a development plan is created. A development plan considers whether the oil deposit is more liquid or solid and how economically feasible it will be to extract oil from the location. It was once the case that test drilling was a common practice. However, due to the cost of drilling a single well, particularly in deep water, and improved techniques for assessment, test wells are seldom drilled now. If a well is drilled, it is In oil shales, the heavy oil is chemically combined with the rock, and requires a chemical separation process to release the oil, such as pyrolysis or hydrogenation. The separation releases vast quantities of waste solids, perhaps yielding 0.2 m 3 of oil per tonne of rock processed.
