Abstract:
1. A system for producing an alpha olefin, comprising: a first isomerization reactor configured to isomerize a first batch of an olefin having a first carbon number to form a first isomerization reactor effluent and subsequently process a second batch of an olefin having a second carbon number to form a second isomerization reactor effluent, a metathesis reactor positioned downstream from the first isomerization reactor, the metathesis reactor being configured to disproportionate the first isomerization reactor effluent to form a metathesis reaction product, a first fractionator positioned downstream from the isomerization reactor and being configured to separately fractionate the first and second isomerization reactor effluents, a second fractionator positioned downstream from the metathesis reactor to remove light hydrocarbons from the metathesis reaction product, a storage tank disposed downstream from the first or second fractionator, and a storage tank outlet line connecting the storage tank to an inlet of the first isomerization reactor and/or to the inlet of the metathesis reactor.
