Title (EN) ABSORBENT REGENERATION WITH COMPRESSED OVERHEAD STREAM TO PROVIDE HEAT
(FR) AMÉLIORATIONS APPORTÉES À LA RÉGÉNÉRATION D'UN ABSORBANT
Abstract:
(EN) A method. and plant for regeneration of a rich absorbent having absorbed C02, to give a regenerated, or lean absorbent, and C02, where the rich absorbent is regenerated by stripping against steam in a regenerating column (8), where gas, mainly comprising released C02 and steam, is withdrawn from the top of the column (9) and separated (25) to give a stream of C02 that is removed, and condensed water (27) that is recycled into the regenerator column, and where lean, or regenerated, absorbent is withdrawn from the base of the column (4), wherein the gas that is withdrawn from the top of the regenerator column (9) is compressed (21) and cooled by heat exchanging to recover the heat (23,24), before separation of the gas into C02 and water.
(FR) La présente invention concerne un procédé et une installation de régénération d'un absorbant riche contenant du CO2 absorbé, qui permettent d'obtenir un absorbant régénéré ou pauvre et du CO2. Le procédé selon l'invention consiste : à régénérer l'absorbant riche par désorption à la vapeur dans une colonne de régénération; à extraire le gaz, qui contient principalement du CO2 libéré et de la vapeur, du sommet de la colonne, et à le séparer afin que l'on obtienne un flux de CO2, qui est enlevé, et de l'eau condensée, qui est recyclée dans la colonne de régénération; et à extraire l'absorbant pauvre ou régénéré de la base de la colonne. Le gaz qui est extrait du sommet de la colonne de régénération est comprimé et refroidi par échange thermique afin la chaleur soit récupérée, puis séparé en CO2 et en eau.
