Method and device for reducing regeneration energy consumption of decarburization absorption liquid

InactiveCN103977683AIncrease temperatureImprove acid gas analysis efficiencyProductsCarbon compoundsSupersonic wavesDecarburization
The invention relates to a method and a device for reducing regeneration energy consumption of decarburization absorption liquid. A heating regeneration process is carried out to a rich solution which absorbs carbon dioxide and is discharged from a bottom of an absorption column. Heat is recovered, by a heat pump, from gas discharged from a top of a regeneration column and/or a heat-exchanged and temperature-reduced barren solution discharged from the bottom of the regeneration column, wherein the heat is supplied to be provided for heating liquid in the bottom of the regeneration column and a heat-exchanged rich solution. With the heat pump, temperature of the rich solution is increased and the energy consumption of heating is significantly reduced, and furthermore, desorption efficiency of acid gas in the regeneration column is increased. After the majority of the rich solution is subjected to a flash evaporation process by reducing the pressure to a normal pressure, the flash-evaporated solution is free of heating regeneration and is directly flowed back to the regeneration column for absorbing high-concentration CO2, so that regeneration amount of the rich solution is greatly reduced with an absorption effect being ensured, thereby regeneration energy consumption is reduced and decarburization operation cost is saved. Supersonic wave is used for desorbing CO2 in a flashed solution so that desorption efficiency of CO2 can be further improved.
