| titleOfInvention | Lightweight olefin separation device capable of reducing usage amount of absorbent |
| abstract | The utility model discloses a lightweight olefin separation device capable of reducing the usage amount of an absorbent. The lightweight olefin separation device comprises a depropanization tower and a demethanization tower, wherein an outlet in the upper end of the depropanization tower is connected to an inlet in the demethanization tower; the upper end of the demethanization tower is connected to an absorption tower through a demethanization tower condenser and a demethanization tower return tank, and the lower end of the demethanization tower is connected to a deethanization tower; a discharging port in the top of the absorption tower is connected to a pressure swing adsorption device; a feeding port in the side surface of the upper end of the absorption tower is connected to the bottom of the deethanization tower or the bottom of a propylene refining tower; and the upper end of the deethanization tower is connected to an acetylene hydrogenation reactor and an ethylene refining tower, the lower end of the deethanization tower is connected to a propyne hydrogenation reactor and a propyne refining tower. The lightweight olefin separation device disclosed by the utility model has the advantages of low investment, low energy consumption, small circulation volume of the absorbent and high recovery rate of materials. |
