  • OPTIMIZED THERMAL SEPARATION BY PRIOR GAS EXCHANGE
    Publication number: 20230250040
    Abstract: A process can be used for preparing aldehydes from C2 to C20 olefins with a subsequent thermal separation for removal of the aldehyde formed. The process involves a membrane separation, which is preceded by performance of a gas exchange by which the proportion of the partial pressure represented by carbon monoxide or hydrogen is increased in order to reduce catalyst losses.
