A method and apparatus for concentrating and recovering ethylene from the off-gas from an apparatus which produces gasoline, propylene and the like by fluidized catalytic cracking (FCC) of heavy oils such as atmospheric residue, generated in a crude oil refining process, is provided. The method and apparatus can reduce the amount of ethylene rinse in the subsequent ethylene displacement desorption process by increasing the ethylene purity of a raw material gas and reducing the concentration of weakly adsorbing components in the raw material gas and can reduce the loss of a desorbent during a distillation process for separating the desorbent from the weakly adsorbing components. Thus, ethylene can be recovered from the off-gas from fluidized catalytic cracking of heavy oils at high concentration and low cost.
