ABSTRACT:
A system and a process for producing methane gas by anaerobic digestion of feed materials containing suitable organic materials. The system includes a plurality of digestion modules arranged primarily in series. Each digestion module is positioned with its slurry inlet port at a slightly lower elevation than the slurry outlet port of the preceding digestion module. The number of digestion modules is dependent upon the particular feed material to be digested. Each digestion module can be sampled and controlled independently. The process includes grinding and pulping the feed material, mixing the feed material with a liquid to prepare a slurry, charging the initial digestion module with slurry and transferring the digesting slurry to the next successive digestion module and subsequently to each successive digestion module after predetermined time periods until the digestion process has been completed. The liquid is separated from the digested slurry for recycle through the system. The resulting sludge is useful for a variety of purposes.
