Described herein is a process for producing an alpha olefin by obtaining a feed stream of internal olefins having a first carbon number and alpha olefins having a first carbon number. The olefins are isomerized to increase the quantity of the alpha olefins. The olefins are then fractionated, subjecting the overhead material to catalytic metathesis to produce a mixed olefin effluent of internal olefins having a second carbon number and other hydrocarbons. The first isomerization reactor and fractionator are prepared to receive the olefins having a second carbon number, where the internal olefin intermediate is isomerized in the prepared first isomerization reactor. The second isomerization effluent is fractionated in the prepared first fractionator to separate the alpha olefins having the second carbon number from the internal olefins having the second carbon number. A corresponding system is also described, along with a heat pump that may be incorporated into the process. |
