  • PROCESS FOR REMOVING EXTRANEOUS ODOUR-FORMING SUBSTANCES FROM HYDROCARBON STREAMS
    Publication number: 20230313054
    Abstract: A process can be used for purifying a hydrocarbon stream containing at least Cx alkanes, Cx olefins, low boilers such as Cx?1 hydrocarbons, and high boilers such as Cx+1 hydrocarbons, with x=3 or 4. The process involves separating off low boilers and separating off high boilers, wherein the separating-off of high boilers is performed in the presence of hydrogen and hence a hydrogenation of the olefins present takes place.
