| titleOfInvention | Method for the Production of Unsaturated Nitriles from Alkanes |
| abstract | The invention provides a) feeding alkanes to the dehydrogenation zone and catalytically dehydrogenating the alkanes to form the corresponding alkenes, whereby alkene, unreacted alkanes, and optionally water vapor, hydrogen, carbon oxides, alkanes or alkenes Obtaining a product gas stream A comprising at least one additional gas component selected from the group consisting of (low boiling point) hydrocarbons, nitrogen and rare gases boiling at low temperatures,n n n b) at least partially separating additional gas components from product gas stream A to obtain feed gas stream B comprising alkanes and alkenes,n n n c) Feed gas stream B, ammonia, oxygen containing gas and optionally water vapor to the oxidation zone, and the alkene is catalytically ammonia oxidized to form the corresponding unsaturated nitrile, whereby unsaturated nitrile, ammonia oxidation byproduct, unsaturated alkane And obtaining a product gas stream C comprising alkene and optionally at least one further gas component selected from the group consisting of water vapor, oxygen, carbon oxides, ammonia, nitrogen and rare gases,n n n d) optionally isolating ammonia from product gas stream C to obtain ammonia depleted product gas stream D,n n n e) unsaturated alkanes and alkenes separated by absorption in an aqueous absorbent from unsaturated nitrile and ammonia oxidation byproducts from product gas streams C or D, and optionally selected from the group consisting of oxygen, carbon oxides, ammonia, nitrogen and rare gases Obtaining a gas stream E comprising at least one additional gas component and an aqueous stream comprising unsaturated nitriles and by-products, obtaining unsaturated nitriles from the aqueous stream, andn n n f) recycling gas stream E to the dehydrogenation zonen n n It relates to a process for the preparation of unsaturated nitriles from the corresponding alkanes comprising: |
