A method of column control, comprising: passing a feed stream comprising C2-C20 linear alpha olefins, solvent, spent catalyst, catalyst deactivation agent, or a combination comprising at least one of the foregoing, and a make-up stream comprising C4 linear alpha olefins through a C4/C6 distillation column; withdrawing an overhead fraction comprising C4- linear alpha olefins from the column, wherein the overhead fraction is in communication with a split-range controller; purging at least a portion of the overhead fraction to allow for control of column pressure, wherein the purged portion of the overhead fraction comprises C4- linear alpha olefins; cooling at least a portion of the overhead fraction in a heat exchanger and passing it through a reflux drum to allow for control of reflux drum fluid levels, wherein the heat exchanger comprises a coolant fluid; withdrawing a purge stream comprising C4- linear alpha olefins and a distillate stream from the reflux drum, wherein the distillate stream has a constant flow rate; recycling at least a portion of the distillate stream back to the column; intermittently using at least a portion of the distillate stream as a liquid condensate supply for downstream equipment; and withdrawing a bottoms fraction comprising C6+ linear alpha olefins, solvent, spent catalyst, catalyst deactivation agent, or a combination comprising at least one of the foregoing, from the column; wherein the reflux drum is in communication with a split-range controller, wherein the split-range controller comprises a reflux drum level controller in communication with a make-up stream flow valve and a coolant stream flow valve; and an overhead fraction in communication with a split-range controller, wherein the split-range controller can comprise a pressure controller in communication with an overhead fraction flow valve and a purge stream flow valve. passing a feed stream comprising C2-C20 linear alpha olefins, solvent, spent catalyst, catalyst deactivation agent, or a combination comprising at least one of the foregoing, and a make-up stream comprising C4 linear alpha olefins through a C4/C6 distillation column; withdrawing an overhead fraction comprising C4- linear alpha olefins from the column, wherein the overhead fraction is in communication with a split-range controller; purging at least a portion of the overhead fraction to allow for control of column pressure, wherein the purged portion of the overhead fraction comprises C4- linear alpha olefins; cooling at least a portion of the overhead fraction in a heat exchanger and passing it through a reflux drum to allow for control of reflux drum fluid levels, wherein the heat exchanger comprises a coolant fluid; withdrawing a purge stream comprising C4- linear alpha olefins and a distillate stream from the reflux drum, wherein the distillate stream has a constant flow rate; recycling at least a portion of the distillate stream back to the column; intermittently using at least a portion of the distillate stream as a liquid condensate supply for downstream equipment; and withdrawing a bottoms fraction comprising C6+ linear alpha olefins, solvent, spent catalyst, catalyst deactivation agent, or a combination comprising at least one of the foregoing, from the column; wherein the reflux drum is in communication with a split-range controller, wherein the split-range controller comprises a reflux drum level controller in communication with a make-up stream flow valve and a coolant stream flow valve; and an overhead fraction in communication with a split-range controller, wherein the split-range controller can comprise a pressure controller in communication with an overhead fraction flow valve and a purge stream flow valve. <EOS>
