No full textSteam Gasification of Tyre Waste, Poplar, and Refuse-Derived fuel: A Comparative Analysis
No full textIn the field of waste management, thermal disposal is a treatment option able to recover resources from end of life products. Pyrolysis and gasification are emerging thermal treatments that work under less drastic conditions in comparison with classic direct combustion, providing for reduced gaseous emissions of heavy metals. Moreover, they allow better recovery efficiency since the process by-products can be used as fuels (gas, oils), for both conventional (classic engines and heaters) and high efficiency apparatus (gas turbines and fuel cells), or alternatively as chemical sources or as raw materials for other processes. This paper presents a comparative study of a steam gasification process applied to three different waste types (refuse-derived fuel, poplar wood and scrap tyres), with the aim of comparing the corresponding yields and product compositions and exploring the most valuable uses of the by-products

No full textThe Building Dynamic Simulation Software ODESSE (Optimal DESign for Smart Energy): Analysis and Suggested Improvement
No full textDynamic simulation software packages allow us to describe a building-plant system over time
and are very useful for estimating energy consumption in architectural projects. However, its use by
professionals in the construction industry is currently rather limited because it is difficult to use. In fact many
dynamic simulation software programs are not widely used because of their complicated Graphical User
Interface (GUI). The software ODESSE (Optimal Design for Smart Energy), developed by ENEA (National
Agency for New Technologies, Energy and Sustainable Economic Development) in Italian and English, has
the great advantage of a simple and intuitive GUI. On the other hand, compared to other programs it is not
yet entirely satisfactory from the technical and mathematical points of view. This article presents an analysis
of ODESSE and some proposals for its improvement, in particular with regard to heat exchange algorithms
between thermal zones of a building and to the program language. In order to achieve these objectives, a new
simulation engine written in C++ has been created that is able to evaluate heat exchanges between zones,
even when they are connected temporarily or permanently by doors or openings of some type. The tests
performed demonstrate the stability of the multi-zone model developed, but the numerical method of
resolution initially used needs to be changed
Karyology and karyotype analysis of diploid freshwater planarian populations of the Dugesia gonocephala group (Platyhelminthes, Tricladida) found in Sardinia
No full textModelling wastewater treatment in a submerged anaerobic membrane bioreactor
No full textMathematical modelling has been widely applied to membrane bioreactor (MBRs) processes. However, to date, very few studies have reported on the application of the anaerobic digestion model N.1 (ADM1) to anaerobic membrane processes. The aim of this study was to evaluate the applicability of the ADM1 to a submerged anaerobic MBR (SAMBR) treating simulated industrial wastewater composed of cheese whey and sucrose. This study demonstrated that the biological processes involved in SAMBRs can be modelled by using the ADM1. Moreover, the results showed that very few modifications of the parameters describing the ADM1 were required to reasonably fit the experimental data. In particular, adaptation to the specific conditions of the coefficients describing the wastewater characterisation and the reduction of the hydrolysis rate of particulate carbohydrate (khyd,ch) from 0.25 d-1 (as suggested by the ADM1 for high-rate mesophilic reactors) to 0.13 d-1 were required to fit the experimental data.
