Process for the purification and utilization of coarse coal in underground gasification
Thread Content
Experts, how can we make rational use of oxygen-enriched gas produced by underground gasification? :The cost of raw gas D is 0.12–0.15 yuan per cubic meter; the gas pressure is 1.2–2.0 MPa. Its composition is: (35–37%) H2, (48–52%) CO2
Doesn’t this one have CO2? What is the oxygen-to-nitrogen ratio of your enriched oxygen?
Gas: 48–52% CO2; in oxygen-enriched conditions, CO2 + O2 is used as the gasification agent
Of course, air + O2 can also be used, with an oxygen-to-nitrogen ratio of 2:1
Actually, the best approach is to use syngas to produce methanol and then proceed with further downstream processing, as this yields high added value. The next option is to produce methane, but the profits are not high. Finally, there’s power generation
