| 简介 |
A method of extraction of fuels and elements from coal, shale, peat and landfill seams is described which cuts the earth with only a main shaft and with auxiliary narrow drillings widely spaced from the shaft. The seam, which is first cooled to brittle cold and fractured with vibrations, is heated to the highest temperature of the hydrocarbon fraction desired to be extracted and the evaporated hydrocarbons are extracted in a Nitrogen gas carrier. To speed the extraction rate, tonal input from two or more organ pipes vibrates the seam structure frees the evaporated hydrocarbons allowing their escape into the shaft. As the extraction continues requiring inclusion of a greater area of the seam structure, narrow drillings are made and Liquid Nitrogen is inserted, first, cooling the extended seam structure to brittle and vibration fracturing the seam structure, and then continuing to provide the seam with Nitrogen gas which seeps into the seam carrying the evaporated hydrocarbons. Further expansion of the field moves the Nitrogen sourcing to the outer circle and inserts auxiliary heaters in the narrow drillings between the outer ring and main shaft bringing more of the seam to the desired extraction temperature. Extracted evaporated hydrocarbons are separated into the hydrocarbons fractions, into fuel types as heating oil, kerosene, gasoline, ethers, and fuel gas, methane, argon and rare gas segments. The thermal gradient of the extraction pipe is implemented by sourcing the Nitrogen from Liquid Nitrogen and running the pipes bundled with the extraction pipe condensing its contents by hydrocarbon fractions in vessels and gas drums depending on boiling points of fractions. Water is separated from the gasoline segment and purified first by separation and then further by freezing. |
