| 摘要 |
The present invention relates to a biomethane purification system, and more specifically, to a biomethane purification system, which enables to purify highly concentrated biomethane without using an additional catalyst, and at the same time, minimizes generation of secondary pollution induced by separated gas in a process of purifying the biomethane. The biomethane purification system of the present invention comprises: a compressed biogas supply unit for compressing biogas containing methane and supplying the compressed biogas; a water under pressure supply unit for supplying high-pressure water under pressure to be mixed with the biogas; a biogas and water under pressure mixing unit installed to be connected between the compressed biogas supply unit and the water under pressure supply unit and mixing the biogas with the water under pressure so as to separate methane gas and other foreign substances from the biogas; an absorbed gas removing unit for deaerating the biogas and the foreign substances separated from the water under pressure mixing unit; and a deaerated gas removing unit for heating the foreign substances deaerated from the absorbed gas removing unit and removing the heated foreign substances. |
