摘要

A device for capture of acid gas of combustion fumes of a thermal power plant, including:
absorption means (10) of the gas by capture fluid,a regenerator (1) where the capture fluid and a regeneration fluid steam are put in contact,introduction means (11) of the regeneration fluid in the regenerator,condensation means (2, 3, 4), at the head of said regenerator,separation means (6) of liquid phase of the regeneration fluid and gaseous phase rich in acid gas,

Wherein:
the regeneration fluid steam introduced is superheated,the regenerator (1) includes means limiting the contact time to substantially maintain the flow rate of regeneration fluid steam,the condensation means (2, 3, 4) are in thermal exchange with first evaporation means of working fluid, andfirst reintroduction means (13) of steam obtained in a turbine (14).

1. A device for capturing acid gas contained in combustion fumes of a thermal power plant including a steam circuit, the device including:
absorption means (10) of the acid gas by contacting the fumes with a capture fluid low in acid gas, a regenerator (1) wherein are put in contact the capture fluid enriched with acid gas and regeneration fluid steam introduced to regenerate the capture fluid, first introduction means (11) of the regeneration fluid steam in the regenerator (1), first condensation means (2, 3, 4) in a medium containing a liquid phase of the regeneration fluid and a gaseous phase rich in acid gas, arranged at the head of said regenerator (1), separation means (6) of the liquid phase of the regeneration fluid and of the gaseous phase rich in acid gas,wherein:
the regeneration fluid steam introduced to regenerate the capture fluid is superheated steam, the regenerator (1) includes contact means between the capture fluid enriched with acid gas and the superheated regeneration fluid steam, limiting the contact time between the two such that the flow rate of regeneration fluid steam is substantially maintained, the first condensation means (2, 3, 4) are means of a first evapo-condenser and are in thermal exchange with first evaporation means of the first evapo-condenser, which evaporate a working fluid, and the device includes first reintroduction means (13) of the steam of the resulting working fluid to a first turbine (14).
