Diseño e implementación de un sistema de supervisión, monitoreo y control de temperatura, presión y tiempo de proceso en un sistema de digestión anaerobia de biomasa (contenido ruminal bovino) a escala de laboratorio.

Abstract

The final disposal of biosolids waste product of industrial, domestic and agricultural business, has triggered a complex set of environmental, economic and social problems; which drive the development of research projects aimed at mitigating some adverse impacts on the planet. Particularly residues of agricultural origin such as bovine rumen contents (BRC) pose a great threat. The implementation of biodigesters is a cost effective and efficient option in the proper management of such waste and the generation of some usable products as an energy resource, which together with control strategies, monitoring and modeling of variables, generate a favorable impact on the environment ambient. The process object of this research called anaerobic digestion is a biochemical process is performed in the absence of oxygen in a chemical reactor (digester), through a series of bacterial events certain conditions as ranges optimum temperature, pH, pressure, etc, transform organic matter into gas composed of methane (CH4), carbon dioxide (CO2) and hydrogen sulfide (H2S). This research documents the methods used in the development of a system of control and supervision by implementing an acquisition card associated variables and a web server via the communication protocols HTTP, SSH and languages programming C, PYTHON and HTML; Biodigestor implemented in a batch laboratory scale; the dynamic model of system behavior for biomass anaerobic digestion ruminal content was subsequently raised cattle.
