Stage: PROBLEM TO BE SOLVED: To provide a light olefin-containing gas production device which can achieve increased production efficiency while effectively utilizing thermal decomposition gas produced from plastic waste.SOLUTION: A light olefin-containing gas production device 100 includes: a first thermal decomposition furnace 10 which produces plastic waste thermal decomposition gas; a second thermal decomposition furnace 20 which produces a thermal decomposition product of a hydrocarbon raw material; a fractionation column 22 which fractionates the thermal decomposition product into thermal decomposition produced gas and a fuel oil; a cooling column 24 which cools the thermal decomposition produced gas obtained from the fractionation; a compressor 26 which compresses the cooled thermal decomposition produced gas and the plastic waste thermal decomposition gas together to produce compressed gas; a second flow channel L2 which connects the cooling column 24 and the compressor 26; a first flow channel L1 which connects the first thermal decomposition furnace 10 and the compressor 26 or connects the first thermal decomposition furnace 10 and the second flow channel L2; and a distillation column 28 which distills the produced compressed gas into a plurality of hydrocarbon fractions including hydrogen and light olefin gas.SELECTED DRAWING: Figure 1 (Grant)
