Description

Technical Field

[0001] This invention relates to the field of extraction technology, and more specifically to a system and method for extracting petroleum from petroleum residues. Background Technology

[0002] Petroleum refers to a mixture of gaseous, liquid, and solid hydrocarbons, occurring naturally. Petroleum is further classified into crude oil, natural gas, liquefied natural gas, and natural tar, but the term "petroleum" is conventionally used to define "crude oil." Petroleum is a viscous, dark brown liquid, often referred to as the "blood of industry." Petroleum is found in certain areas of the Earth's upper crust. Its main components are mixtures of various alkanes, cycloalkanes, and aromatic hydrocarbons. It is one of the primary targets of geological exploration. There are two main theories regarding the formation mechanism of petroleum: biogenic sedimentary petroleum formation and petrochemical petroleum formation. The former, which is more widely accepted, posits that petroleum is formed from ancient marine or lake organisms through a long evolutionary process, thus being a non-renewable biogenic sedimentary petroleum. The latter theory suggests that petroleum is formed from carbon within the Earth's crust itself, unrelated to biological processes, and is therefore renewable. Crude oil, when processed by an atmospheric and vacuum distillation unit, can be separated into various fuels and petroleum residues. Some petroleum residues will be adhering to the residues, and most of these residues are discarded, resulting in material waste, reduced oil extraction rate, increased costs, and decreased work efficiency. Therefore, in order to address the defects and shortcomings of petroleum extraction mentioned above, it is urgent to improve petroleum extraction technology, avoid material waste, and improve petroleum extraction efficiency, thereby providing a system and method for petroleum extraction from petroleum residues.
