ABSTRACT:
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 absorbent;(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.
