| titleOfInvention | A system for separating heavy hydrocarbons in natural gas by cryogenic method |
| abstract | The utility model relates to a system for separating heavy hydrocarbons in natural gas by cryogenic method. The system of the utility model includes a cold box (1), a demethanizer (2) with a rectification section and a stripping section, an inlet heater (3), a return tank (4), a return pump (5) and a stabilizer Tower (6). First, use the rectification section of the demethanizer (2), the reflux tank (4) and the reflux pump (5) to completely remove the heavy hydrocarbons in the natural gas; The device (3) strips the heavy hydrocarbons separated in the rectification section of the demethanizer (2) to further purify the heavy hydrocarbons and recover the light components; finally, the liquid phase at the bottom of the demethanizer is sent to the top of the stabilization tower for further stripping and purification To remove heavy hydrocarbons, qualified heavy hydrocarbon products will be obtained at the top of the stabilization tower, and the top gas phase will be directly used as fuel gas for the plant. The system of the utility model uses the second channel of the cold box (1) as the top condenser of the demethanizer (2), so that the deheavy hydrocarbon process is coupled in the natural gas liquefaction process, and the process integration is high. The system of the utility model Good stability, wide applicability and strong operability. |
