| titleOfInvention | Cryogenic separating system for preparing liquefied natural gas with oven gas |
| abstract | The invention discloses a cryogenic separating system for preparing liquefied natural gas with oven gas. The cryogenic separating system comprises a methane-hydrogen rectifying tower, a methane-nitrogen rectifying tower, a feed gas cooler, a nitrogen subcooler, a tower top condenser I of the methane-hydrogen rectifying tower, a tower top condenser II of the methane-hydrogen rectifying tower and a tower bottom reboiler of the methane-hydrogen rectifying tower constituting a cryogenic separating pipeline system, a hydrogen-rich recovering pipeline system and a nitrogen-rich pipeline system for natural gas, and further comprises a two-stage nitrogen expanding refrigerating circulation loop for supplying cold energy to the feed gas cooler and the nitrogen subcooler. The cryogenic separating system for preparing liquefied natural gas with oven gas has the advantages of low cost, small investment, stable system, easiness for operating and high natural gas recovering rate. |
