요약

The present invention relates to a method and system for separating CO2 based on regenerative chemical absorption, including an absorber where the CO2 remains retained in an absorbent liquid, and including a regenerator where the CO2 is released, obtaining a regenerated absorbent that is re-used in the absorption unit. The invention proposes a configuration of the entire capturing process which allows an efficient operation that significantly reduces the energy requirements mainly associated with the regeneration of the absorbent, as well as a lesser thermal degradation of same.[Image]

대표청구항

Method for separating CO2 from a gas stream based on chemical absorption, comprising the following steps: a) absorbing the CO2 coming from the gas stream to be treated at a temperature of between 40 °C and 60 °C and a pressure in a range of between 1 and 1.5 bar, by means of putting said stream in contact in an absorber with an absorbent solution in which the CO2will be retained; b) recirculating into the absorber up to 75 % of the stream comprising the CO2-rich absorbent solution coming from step a); c) desorbing CO2 in a regenerator from the stream comprising the CO2-rich absorbent solution coming from step a) not recirculated to step b) at a temperature of between 80 °C and 120 °C a pressure of between 1.5 and 5 bar and a steam stripping flow rate of between 10 and 90 % by volume with respect to the desorbed CO2 flow rate, where said stream is split into at least two streams by means of a set of heat exchangers, prior to the inlet of the regenerator; d) recovering the absorbent solution resulting from step c) from the absorber of step a).
