Abstract
Our study focuses on optimizing the electrical efficiency of the biogas plant in the Oujda controlled landfill, with the aim of improving its economic and overall rate of return. For this purpose, the study begins with an analysis of the power generation and operating times of the station which showed a yield not exceeding 23%. These results are due to the control lack over the quantity of biogas and its biomethane content extracted directly from the burial dump of the landfill, and its fluctuation during the day. In this case, the throughput improvement is capped to ensure average production that cannot exceed 15 h of work per day.
To achieve our goal, we have carried out three scenarios for the design of a batch digester methanation unit. The 1st scenario is the one where we add a second motor without affecting the performance of the first, in the 2nd scenario we add a second motor and we fill the missing difference of the first so that they both work at maximum capacity. In the third scenario, we only compensate the amount of biogas missing from the first motor without adding a second one.
