Study of a downdraft gasifier and gas engine fueled with olive oil industry wastes

Experimental and economic study of a gasification plant fuelled with olive industry wastes

“…Prior to this study, the authors presented the steady state performance parameters of different CHP technologies (MGT, EFGT and ICE) coupled to combustion or gasification processes (Vera et al, 2011(Vera et al, , 2012(Vera et al, , 2013. These works described the modeling and simulation approaches, but need to be validated in a real scenario (pilot plant or prototype).…”

Experimental Study on Gasification of Jatropha Shells in a Downdraft Open Top Gasifier

“…An atmospheric fluidized bed gasifier was used for gasification of untreated and leached olive residue, and co-gasification of olive residue, reed, pine pellets and Douglas fir wood chips [10]. Vera et al [11] carried out an experimental and modeling study of a downdraft gasifier and gas engine. The gasifier was operated with olive oil industry wastes (small branches and leaves and olive pits).…”

Modeling and Experimental Study of a Small Scale Olive Pomace Gasifier for Cogeneration: Energy and Profitability Analysis

“…For instance, in [55] different models with increasingly high level of complexity have been proposed, and the results show that a simplistic use of the default gasifier module determines an under-estimation of the methane molar percentage into the syngas. The researches proposed in [55][56][57][58] suggests the following improvements to the downdraft biomass gasification model: (i) modeling three cascade reactors, simulating respectively the pyrolysis, oxidation and reduction zones; (ii) separation of a fraction (5% by mass) of the inlet carbon content, in order to take into account the unavoidable losses occurring in the gasifier due to char formation; (iii) bypass of a fraction of the methane formed during the pyrolysis directly to the reduction outlet, in order to reflect the unavoidable losses and the impossibility to achieve a complete equilibrium composition during the gasification. In light of this state of art on gasification modelling, we here propose an original approach based on interconnection of thermochemical components and informed by experimental data at lab scale, as described in the following section.…”
