Abstract: A method for extracting methane purifies a biogas and components present in the biogas, such as carbon dioxide, sulfur compounds, and ammoniac are separated in a plurality of different process steps. The method for extracting methane is characterized by low energy consumption and allows an increase in methane content of at least 10%. In a first purifying step, carbon dioxide, hydrogen sulfide, ammoniac, and other water-soluble organic substances present in the raw gas are removed in a washing column at a standard pressure or at overpressure of up to 6 bar by use of fresh water. The methane gas having a methane content of at least 65% is drawn off at the head of the washing column. Methane and carbon dioxide dissolved in the wash water are sequentially separated from the contaminated wash water discharged from the washing stage, in a first stripping column and subsequently in a second stripping column, by adding stripping air under standard pressure.

Abstract: The various embodiments herein provide a method to acquire seismic data to estimate reservoir characteristics in a shallow sea water environment. According to an embodiment herein, a method comprises acquiring four component ocean bottom cable (4C OBC) seismic data using a hydrophone and a three component geophone by varying a time delay between the shots and spacing between the shots.
