Biomass to methane production systems have the potential of supplying 25% of the yearly national natural gas demand. The production systems associated with this conversion process are anaerobic digestion facilities. The optimal operation of a batch biomass digester system requires the scheduling of all batches from multiple feedstocks during a fixed time horizon. A significant characteristic of these systems is that the feedstock decays in storage before use in the digester system. The optimal batch residence times in the digester must account for the production rate as well as the decay rate of stored biomass. The availability times, biomass quantities, biogas production rates and storage decay rates must all be taken into account for maximal biogas production to be achieved during the planning horizon. This paper addresses the scheduling of both single and multiple feedstocks in a single digester system. The single feedstock batch scheduling time problem is solved by a dynamic programming algorithm. The multiple feedstock problem is solved by a decomposition approach where the master level allocates time to each feedstock while the subproblems schedule batches within these time allocations. |
