Abstract

Ranches of Mexico’s southeast region have an important energetic potential on their organic waste that remains unexploited. The objective of this work is to present the construction and operation of a floating dome “Biodigester” in a ranch located in Jalapa, Tabasco, Mexico, in addition to the analysis of produced biogas and its electric energy generation. The construction was based in the specifications of a Puxin® biogas plant. The biogas was analyzed using infra-red spectrometry with Fourier transforms. Electric energy was generated using an Energetic ® motor-generator. The methane and carbon dioxide percentage at 90 days of hydraulic retention time (HRT) was 51.51 and 29.05%, respectively. The electric energy generation was 3.58 kWhm-3.

 

Key words: Biomass, floating dome, energy, biodigestate, biogas.
