Abstract:
The method includes limiting saturation of output absorbent with dispersed and recirculating gas molecules with full completion of chemical reactions in the first stage, countercurrent contact between the gas and absorbent in the loading elements of the nozzle in the second stage, further extraction of gas molecules by absorbent in the irrigation chamber of the third stage. Then the gas for the absorption of hard-to-recover components is transferred to the irrigation chamber of the fourth stage, where it is irrigated with fine droplets of fresh and circulating absorbent. Then the direct-flow contact between the gas-liquid phase is carried out in the checker loading elements of the fifth stage. Finally, interphase contact of depleted gas with absorbent is completed in the bubbling chamber of the sixth stage and in the interchamber space between the fifth and sixth chambers.The bubbling chamber of the I stage is divided by a partition into the final and the main bubbling chambers, and the ceramic dispersants and/or hypersonic Hartmann's oscillators are installed in them. The pipeline of the removal of the saturated absorbent is attached to the final chamber, and the circulation pumps are attached to the main chamber of the I stage the and bubbling chamber of the VI stage, the pressure pipelines of the circulation pumps are connected to the scattering reflectors of the irrigation chambers of the III and IV stages. The pressure pump pipeline for supplying the fresh absorbent is connected to the hypersonic acoustical dispersant and the scattering reflectors which are set in the irrigation chamber of the IV stage. The space between the chambers of the I and the II stage is closed and attached by the pipeline of the gas discharge conduit to the distribution nozzles mounted at the bottom of the checker chamber of the II stage. The pipeline for the gas outlet conduit of irrigation chamber of the III stage is attached to the irrigation chamber of the IV stage. The pipes of supply, bypass and gas withdrawal and absorbent are equipped with the magnetic valves. Pumps are equipped with frequency converters (inverters). Valves, inverters and air conditioner are connected to the unit of the automatic control system.The invention allows to achieve the effect of a finite solubility of hard-to-recover gas components in the liquid and the automation of technological processes in order to reduce the power consumption.
