Harvested from ORCID Public Data FileJean-Noël Jaubert in OpenAIREAbstract Contributing to extending the knowledge for the design and operation of biodiesel production processes, isobaric PTxy vapor-liquid equilibria data of ethanol + ethyl hexanoate, 1-pentanol + ethyl hexanoate and 1-pentanol + ethyl octanoate at two different pressures are reported for the first time. Consistency tests were applied to attest the quality of the collected data, for these especially complex measurements. Besides that, vapor pressures of the pure ethyl esters have also been measured. For modeling purposes, the Lyngby and Dortmund UNIFAC variants were used to predict the VLE phase diagrams. Generally, the predictions are of very good quality, being the UNIFAC-Do (Dortmund) better, as the deviations in temperature and vapor compositions are always lower to 1.0 K and 0.020, respectively. Checking for the viability for extrapolations in pressure, CPA EoS was also applied to the modeling of the experimental data with very good results. Finally, aiming at examining the model capabilities to describe multicomponent systems, VLE measurements involving two alcohols and the fatty acid ethyl ester mixture obtained from non-edible vegetable oil have been carried out showing the good performance of the predictive models.

Harvested from ORCID Public Data FileGiuseppe Toscano in OpenAIREAbstract Bioenergy is one of the main contributors in the renewable energy markets but the quality of solid biomass is often a concern. This study provides an application of the ISO 18135 on biomass sampling, evaluating how sampling procedure affects the analytical results and suggesting possible solutions to reach an acceptable level of precision for quality assessment. A sampling plan compliant with the aforementioned standard was carried out in a 21 MW biomass power plant located in Northern Italy in August and February, collecting samples of different typology from heaps stored in the plant and from trucks coming from suppliers. Moisture content analysis was performed for all the samples, and for those from heaps ash and nitrogen contents were also investigated. Considering moisture content, to achieve a good precision, a significantly different number of increments are needed in August and February. Regarding ash content, it would be impossible to obtain the precision suggested by the standard, because it would lead to a number of increments not in line with practical operations. Nitrogen content is not a concern in this case, because of the measured low values. In general terms, precision values suggested by ISO 18135 require a high effort by operator and resulted unsuitable in terms of practical application for moisture and ash contents. This is probably due to the different solid biomass considered during the standard development. For this reason, it is important to assess the quality of the different solid biofuels in order to tune the sampling procedure accordingly.

Harvested from ORCID Public Data FileFabrizio Scala in OpenAIREThe production of synthetic methane using CO from flue gases and green hydrogen appears to be a promising way to combine the concepts of renewable energy, chemical storage, and utilization of CO. Recently, a new reactor configuration for catalytic methanation has been proposed, integrating sorption-enhanced methanation and chemical looping in interconnected fluidized bed systems. This configuration would ensure high methane yields while keeping good temperature control and low operating pressure. In this work, such novel system layout for the catalytic production of methane was combined with a calcium looping unit for CO capture from flue gases of a coal-fired power plant, and with a water electrolyzer sustained by renewable energy. The integrated layout offers a series of advantages deriving from the integration of different mass and energy flows of the different sections of the plant. The performance of this latter was assessed in terms of construction and production costs, as well as from an environmental point of view: a life cycle assessment was carried out to quantify the environmental impact of all process units. Results of the techno-economic analysis indicated that the production cost of methane is higher than that of natural gas (0.66 vs 0.17 EUR/Nm), but lower than that of biomethane (1 EUR/Nm). The largest impact on such costs comes from the PEM electrolyzer. The LCA analysis showed that the environmental performance is better in some categories and worse in others with respect to traditional scenarios. Again, the PEM electrolyzer appears to account for most of the environmental impacts of the process.

In this context, the thermochemical valorisation of tannery sludge (TS) by hydrothermal liquefaction (HTL) process represents a promising route both for the reduction of the material to dispose in landfill and for the production of an energy carrier. HTL process produces bio-crude from wet biomasses in a hot pressurised water environment, thus avoiding the energy-intensive drying step commonly associated to other thermochemical processes. Moreover, HTL, not aiming at the complete oxidation of the organic component, potentially avoids the oxidation of Cr in its harmful hexavalent form. In this study, a TS was investigated as solid waste for HTL carried out in a 500 mL batch reactor to obtain a bio-crude for energy purposes. Results show that, under the best operating HTL condition (350 °C and 10 min), the H/C ratio of bio-crude was similar to that of starting biomass while the O/C ratio was about three times smaller than in the parent TS. The bio-crude yield was about 25–30 % on dry and ash-free basis, with an associated energy recovery of about 40–45 %. NMR analysis of bio-crude revealed that it is a complex mixture mainly constituted by aliphatic units. Moreover, ICP-MS, atomic absorption and UV–visible spectroscopy analyses proved that inorganic elements are mainly retrieved in the solid residue, and that Cr was present in its starting trivalent form.

Harvested from ORCID Public Data FileBaldassarre Venezia in OpenAIREAbstract The research of renewable alternatives to decarbonize the transport sector and to reduce the consumption of fossil fuels pushes towards the development of more sustainable solutions for fuel production. Among the diesel substitutes, hydrotreated vegetable oil (HVO) is considered one of the most promising options, since it can be blended with fossil diesel without limitations. In this context, this paper assesses the technical and economic feasibility of producing HVO using waste vegetable oil (WVO) as feedstock, with the help of a simulation model that maximizes the integration of renewable energy sources. The process to synthesize HVO requires a large amount of hydrogen that, in this study, is supplied through an upstream high-temperature electrolysis process occurring in solid oxide electrolysis cells (SOECs), which are fed by low-carbon electricity. The use of waste oils as feedstock eliminates the competition with food crops (e.g. soybean or rapeseed) and promotes the recycling of substances that need to be disposed. The results of the study prove the technical feasibility of a plant with an annual capacity of 100 kt of HVO, having an energy efficiency of 80%. Also, the breakeven point of such investment would be reached before the fourth year of operation, considering a WVO price of 400 €/t, which is assumed as target price. However, the uncertainty on the market prices of WVO, HVO and electricity, as well as on other fixed and variable production costs, can significantly affect the projected results.

Harvested from ORCID Public Data FileDell'Isola, Marco in OpenAIREThe reduction of the dioxin levels in the exhausts of today waste-to-energy plants relies on the control of the thermo-fluid-dynamic processes occurring within the combustion chamber, rather than on policies aimed at restricting the amount of chlorine in the waste material to be treated. This is a consequence of the fact that waste-to-energy plants currently receive the bulk of discarded PVC and other chlorine sources that are deliberately burned in order to increase the waste heating value. Indeed, severe law regulations are into force in many industrialised countries, posing constraints on the value of some relevant in-chamber thermo-fluid-dynamic variables, such as temperature and residence time of the gases resulting from the combustion process, whose accurate experimental monitoring is extremely expensive and difficult to achieve. The present work analyses the shortcomings of the methods generally employed in full scale plants for the verification of the temperature and residence time of gases produced during the combustion process, and presents the advantages of using a new procedure developed by authors, based on the numerical simulation of the waste combustion process to optimise monitoring of the quantities of interest. The verification of the developed model, which accounts for both the solid and the gaseous phases, and for the various modes of heat and mass transfer between these phases, is obtained through a comparison with the results of an experimental campaign carried out on a full scale plant in Italy. The temperature distribution in the combustion chamber is calculated considering various waste compositions, and both forced and mixed convection. In fact, it is also shown that neglecting buoyancy effects may lead to appreciable errors.

Harvested from ORCID Public Data FileDell'Isola, Marco in OpenAIREThe reduction of the dioxin levels in the exhausts of today waste-to-energy plants relies on the control of the thermo-fluid-dynamic processes occurring within the combustion chamber, rather than on policies aimed at restricting the amount of chlorine in the waste material to be treated. This is a consequence of the fact that waste-to-energy plants currently receive the bulk of discarded PVC and other chlorine sources that are deliberately burned in order to increase the waste heating value. Indeed, severe law regulations are into force in many industrialised countries, posing constraints on the value of some relevant in-chamber thermo-fluid-dynamic variables, such as temperature and residence time of the gases resulting from the combustion process, whose accurate experimental monitoring is extremely expensive and difficult to achieve. The present work analyses the shortcomings of the methods generally employed in full scale plants for the verification of the temperature and residence time of gases produced during the combustion process, and presents the advantages of using a new procedure developed by authors, based on the numerical simulation of the waste combustion process to optimise monitoring of the quantities of interest. The verification of the developed model, which accounts for both the solid and the gaseous phases, and for the various modes of heat and mass transfer between these phases, is obtained through a comparison with the results of an experimental campaign carried out on a full scale plant in Italy. The temperature distribution in the combustion chamber is calculated considering various waste compositions, and both forced and mixed convection. In fact, it is also shown that neglecting buoyancy effects may lead to appreciable errors.

Harvested from ORCID Public Data FileArash Arami-Niya in OpenAIRE Fuyu Jiao; Armand Karimi; Armand Karimi;Abstract The liquefaction of natural gas is an energy intensive process, requiring at least 5% of the energy associated with methane's lower heating value. Key to estimating and optimizing these energy requirements are process simulations which rely upon calculated thermophysical properties of the natural gas. In particular, the prediction of thermophysical properties of natural gas mixtures at pressure-temperature conditions close to the mixture’s critical point or cricondenbar is challenging but important as often natural gas processes operate close to these conditions. In this work, we present a comprehensive study of two natural gas related systems: (CH4 + C3H8 + CO2) and (CH4 + C3H8 + C7H16) with n-heptane fractions up to 15 mol%. High accuracy measurements of densities, at temperatures from 200 K to 423 K and pressures up to 35 MPa are presented. The extensive experimental data collected for these mixtures were compared with the GERG-2008 equation of state, as implemented in the NIST software REFPROP. The relative deviations of the measured densities from those calculated using the GERG-2008 model range between (−2 to 4)% for all mixtures, presenting a systematic dependent on mixture density and n-heptane content. Finally, a case study is presented that probes the impact of the accuracy of density on the pinch point in a simulated LNG heat exchanger. An uncertainty in the density of 1% is shown to cause significant 30% reduction in the minimum approach temperature difference, suggesting that accurate thermophysical property calculations are key to reducing over-design of processing plant.
