| Abstract: | The membrane separation technology can be used to reclaim the hydrogen in the purge gas of associated methanol during the production of city gas, the hydrogen can be re-fed to the synthesis system to adjust the H/C ratio to 2.05-2.20. which is the best operation range, and thus increase the effective content of the synthesis gas, decrease the energy consumption, reduce the occurrence of the subsidiary reactions and improve the synthetic ratio of the methanol. This technology has been applied in the 80 kt/a Unit of Yima Gas Plant of Henan Coal Gasification Project and has achieved good effect. |
