    • The invention is in the field of biogas production. In particular the invention is directed to a process and apparatus for the conversion of carbon and hydrogen containing materials into biogas (viz. a gas stream comprising CH4) containing material and subsequent purification of the resulting gas. According to the invention biogas is produced from carbon and hydrogen containing starting material. The unpurified biogas is subsequently purified by subjecting it to a filtration step, which comprises feeding said biogas to at least one cyclone providing cyclone action, at least one water filter where said biogas is washed with water and at least one dry filter where said biogas is dry-filtered, thus producing a purified biogas, followed by subjecting said purified biogas to compression, preferably using a water ring compressor, followed by feeding the compressed gas to a water-gas separator.
    • 本发明在沼气生产领域。 特别地,本发明涉及用于将含碳和氢的材料转化为生物气体(即包含CH 4的气流)的材料并随后纯化所得气体的方法和装置。 根据本发明,沼气由含碳原料和含氢原料生产。 未净化的生物气体随后经过过滤步骤而被纯化,所述过滤步骤包括将所述生物气体进料至提供旋风作用的至少一个旋风分离器,至少一个水过滤器,其中所述生物气体用水和至少一个干燥过滤器,其中所述生物气体是 干燥过滤,从而产生纯化的沼气,然后优选使用水环压缩机对所述纯化的沼气进行压缩,然后将压缩气体送入水煤气分离器。
