Patent ID: 8865955

Claim:
A process for oligomerizing one or more hydrocarbons, comprising: A) providing a washed feed comprising one or more C3 and C4 hydrocarbons to a first separation zone, wherein the washed feed comprising one or more C3 and C4 hydrocarbons has been waterwashed to remove one or more nitrile compounds; B) separating, via the first separation zone, a first stream comprising an effective amount of C3 olefins for oligomerizing; C) drying at least a portion of the first stream to reduce water in the first stream and producing a dried first stream; D) separating, via the first separation zone, a second stream comprising an effective amount of one or more C4 olefins for oligomerizing, wherein the second stream is substantially free of water; E) providing at least a portion of the dried first stream to a first oligomerization zone for producing a first effluent stream comprising both a C9 hydrocarbon and a C12 hydrocarbon; F) providing at least a portion of the second stream to a second oligomerization zone for producing a second effluent stream comprising both a C8 hydrocarbon and a C12 hydrocarbon, wherein the second effluent stream is a separate stream from the first effluent stream; G) providing at least a portion of the first effluent stream and at least a portion of the second effluent stream to a second separation zone; and H) separating, via the second separation zone, into at least one stream comprising one or more C8, C9 and C12 hydrocarbons.
