| titleOfInvention | Method for recovering ethane in high-pressure natural gases |
| abstract | The invention discloses a method for recovering ethane in high-pressure natural gases, relating to the technical field of natural gas processing technology. The method is characterized by combining high-pressure and low-temperature absorption, partial low-temperature gas supercooling, an externally transported gas reflux process and refrigeration with an expansion machine and dividing both the supercooled gas in a low-temperature separator and externally transported gas reflux into two parts, wherein one part of the supercooled gas and the externally transported gas reflux enter a high-pressure absorption tower and the other part of the supercooled gas and the externally transported gas reflux enter a demethanizer to improve the ethane recovery rate which can be adjusted according to the target value of the recovery rate. The method has the beneficial effects that the operating pressures of the high-pressure absorption tower and the demethanizer can be independently arranged, thus reducing the compression power of an externally transported gas booster set and the heat load of a reboiler of the demethanizer; the method is suitable for devices with feed gas pressures more than 7.0MPa for recovering ethane in the natural gases and has the characteristics of high recovery rate, low system energy consumption, and the like. |
