    • A purification device for biogas of the present invention controls the operation of an absorption module by the methane concentration of the biogas, and collects and recirculates bio-methane generated when the methane concentration is short for improving the quality of the final bio-methane. The decrease of purification capacity of the device by the change of temperature in atmosphere or biogas is prevented for improving the purification capacity, increasing the production amount of bio-methane, and improving the quality of bio-methane.

    • The present invention relates to an apparatus and method for purifying biogas. The apparatus for purifying biogas according to the present invention is characterized by including: a purification unit removing hydrogen sulfide and siloxane contained in supplied biogas; a pressure swing suction unit producing bio-methane by receiving a purified biogas from the purifying unit and removing carbon dioxide; and a first return unit controlled to return the bio-methane to the supply line when measured methane concentration in the bio-methane produced by the pressure swing suction unit is smaller than a preset first reference level. According to this, the present invention provides an apparatus for purifying biogas in which a return rate of methane may be improved by returning bio-methane below the reference level of vehicle fuel among the produced bio-methane, and may also be improved by selectively returning a part of remaining gas and purge gas containing carbon dioxide discharged in the process, and amount of methane discharged into the atmosphere may be minimized.
    • 本发明涉及一种净化沼气的设备和方法。 根据本发明的净化沼气装置的特征在于包括:净化单元去除供应的生物气体中含有的硫化氢和硅氧烷; 通过从净化单元接收净化的沼气并除去二氧化碳来生产生物甲烷的压力回转抽吸单元; 以及第一返回单元,其被控制为当由所述压力摆动抽吸单元产生的生物甲烷中的测量的甲烷浓度小于预设的第一参考水平时将所述生物甲烷返回到所述供应管线。 据此,本发明提供了一种用于净化生物气体的装置,其中可以通过将生物甲烷返回到生产的生物甲烷中的车辆燃料的参考水平以下来提高甲烷的返回率,并且还可以通过选择性地返回 在该过程中排放的二氧化碳的剩余气体和吹扫气体的一部分以及排出到大气中的甲烷量可以最小化。
