Project Info
| Industry | Natural Gas / LNG BOG Helium Extraction |
| Product Name | Membrane Separation Concentration Unit |
| Feed Gas Composition | CH4: 9.40%, N2: 79.95%, He: 9.86%, H2: 0.79% |
| Feed Gas Flow Rate | 520 Nm³/h (0.44 MMSCFD) |
| He+H2 Product Purity | >98% mol (gas) |
| He+H2 Recovery Rate | >97% |
| Project Location | Ordos, China |
| Delivery Date | 2023 |
Using RefineTek's proprietary membrane separation technology, the project pre-concentrates the low-concentration helium and hydrogen resources in the feed gas, raising the combined He+H2 concentration above 98% mol with a recovery rate above 97% — substantially reducing the load on, and improving the overall economics of, downstream deep separation and purification. The system uses a modular skid-mounted design with a short installation and commissioning cycle, and has been running stably at the Ordos project site.
