| titleOfInvention | Olefin separation system and olefin separation method |
| abstract | The invention provides an olefin separation system and an olefin separation method. The olefin separation system comprises a demethanation unit, wherein the demethanation unit comprises a primary demethanation tower, a membrane separation assembly and a secondary demethanation tower, a first gaseous phase logistics pipeline is arranged between the tower top outlet of the primary demethanation tower and the inlet of the membrane separation assembly, and a hydrocarbon-enriched gas flow pipeline is arranged between the hydrocarbon-enriched gas flow outlet of the membrane separation assembly and the inlet of the secondary demethanation tower. The first gaseous phase flow is obtained by non-clearly cutting or clearly cutting the to-be-separated gas through the primary demethanation tower by the olefin separation system, the first gaseous phase flow is further separated into hydrocarbon-enriched gas flow and hydrogen-enriched gas flow through the membrane separation assembly, and the CH4/H2 molecule ratio in the hydrocarbon-enriched gas flow entering the secondary demethanation tower is increased so as to increase the partial pressure of CH4 at the top of the secondary demethanation tower and to reduce the energy consumption required for cooling and investment and operating cost of olefin separation. |
