Mejora de un sensor basado en la diferencia de dilución de gases en agua para la medición de la fracción de metano contenido en un flujo de biogás generado en un proceso de digestión anaerobia
No full textAutomatic Carbon Dioxide-Methane Gas Sensor Based on the Solubility of Gases in Water
No full textBiogas methane content is a relevant variable in anaerobic digestion processing where knowledge of process kinetics or an early indicator of digester failure is needed. The contribution of this work is the development of a novel, simple and low cost automatic carbon dioxide-methane gas sensor based on the solubility of gases in water as the precursor of a sensor for biogas quality monitoring. The device described in this work was used for determining the composition of binary mixtures, such as carbon dioxide-methane, in the range of 0–100%. The design and implementation of a digital signal processor and control system into a low-cost Field Programmable Gate Array (FPGA) platform has permitted the successful application of data acquisition, data distribution and digital data processing, making the construction of a standalone carbon dioxide-methane gas sensor possible
