| contents | Finding the optimal parameters for the steam explosion process of hay Josef Maroušek Ingeniería biogas production Extrusion dynamics process optimization Combining biochemical principles and mathematical methods were defined optimal extrusion(steam explosion) process conditions for pelleted hay resulting in maximal cumulative production ofbiogas (CBGP). Operating experiments were conducted on a continuous modifiable extruder. Variable pa-rameters, the reaction time, pressure and dry mass were compared and optimized. An assumption thatlonger reaction time, lower dry mass and higher operating pressure results in higher yields of biogas wereconfirmed only in defined pressure range. Critical conditions, from where the yield starts to decrease dueto inhibitors formations were also modeled. It was found that the optimal process conditions were in theneighborhood of pressure 1.3 MPa, reaction time 7 minutes and 8% of dry mass resulting in 405 m3ofbiogas (52.3% CH4) per ton of dry mass. 2012 artículo científico 0254-0770 https://www.redalyc.org/articulo.oa?id=605767222006 en http://www.redalyc.org/revista.oa?id=6057 Revista Técnica de la Facultad de Ingeniería, Universidad del Zulia application/pdf Universidad del Zulia Revista Técnica de la Facultad de Ingeniería, Universidad del Zulia (República Bolivariana de Venezuela) Num.2 Vol.35 |
