BIOMASS DIGESTER SYSTEM & PROCESS

摘要

A biomass digester system for generating biogas includes a battery of flexible, elongate digesters (10), at least one common biogas accumulator, connection means for connecting the digesters in gaseous communication with the accumulator and valve means fitted to the connection means, for adjusting flow of the biogas through the connection means thereby to permit a digester to be disconnected from the accumulator and taken offline. Each digester may include a flexible bag adapted to withstand pressure of the order of two bars, an inlet for biomass and an outlet for biogas. Also provided is a process for producing biogas from biomass.
