(FR) PROCÉDÉ DE SÉPARATION D'UNE OLÉFINE D'UN FLUX GAZEUX
Abstract: front page image
(EN)The present invention relates to a method of separating an olefin from a gas stream, said gas stream comprising the olefin and at least one other component, said method comprising (i)compressing and cooling the gas stream; (ii) separating the olefin from the gas stream by absorbing the olefin in an absor-bent; (iii) separating the olefin from the absorbent by desorption; wherein compressing or cooling or compressing and cooling in (i) is carried out at least twice.
(FR)L'invention concerne un procédé de séparation d'une oléfine d'un flux gazeux, lequel comprend l'oléfine et au moins un autre composant, le procédé consistant : (i) à comprimer et à refroidir le flux gazeux; (ii) à séparer l'oléfine du flux gazeux par absorption de l'oléfine dans un absorbant; et (iii) à séparer l'oléfine de l'absorbant par désorption; la compression ou le refroidissement ou la compression et le refroidissement à l'étape (i) étant effectués au moins deux fois.
