Formation conditions of biogas hydrate

Biogas is high quality green energy, its main compositions of the biogas are methane, carbon dioxide and hydrogen sulfide. Methane of high purity from biogas is of great significance to environment protection and equipment protection. Great differences of formation pressure among methane hydrate, carbon dioxide hydrate and hydrogen sulfide hydrate in water make it available for biogas separation with gas hydrate method. Formation conditions of biogas hydrate was simulated by a new gas hydrate model and a modified model was put forward by corresponding experimental data. Above research is valuable for methane from biogas.
