Abstract
A method for producing an olefin oligomer mixture comprising: feeding a raw olefin oligomer mixture to a first evaporator; feeding a residue which is taken out from the first evaporator to a second evaporator, and returning a distillate which is distilled from the second evaporator to the first evaporator; taking a distillate out from the first evaporator; feeding a residue which is taken out from the second evaporator to a third evaporator; and taking a distillate out from the third evaporator.
