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.Type: GrantFiled: April 2, 2009Date of Patent: June 3, 2014Assignee: Lummus Technology Inc.Inventors: Robert J.
