CO2 capture and storage (CCS) is a technological solution to stabilize or even reduce the atmospheric concentration of greenhouse gas CO2, mitigate climate change. In this context, MgO promising solid sorbent, as energy penalty sorbent regeneration comparatively small, but it requires addition promoters, typically alkali metal nitrates, yield acceptable kinetics. Under operating conditions, promoters are in molten state. The main objectives work (i) assess experimentally validity different...
Municipal solid waste incineration (MSWI) is a method of valorization whose overall sustainability depends on the effective removal gaseous contaminants generated. Hydrogen chloride (HCl) typical pollutant formed in combustion. Dry processes based its reaction with basic powders such as calcium hydroxide are among state-of-the-art best available technologies for MSWI flue gas treatment. An experimental investigation heterogeneous process between hydrogen and temperature range 120 180 °C was...
The use of sodium bicarbonate (NaHCO3) as a solid reactant for the removal acid pollutants in industrial flue gas streams is simple and effective process solution. Nonetheless, despite its technological maturity, application NaHCO3-based treatment still highly empirical. A better knowledge heterogeneous reaction could allow optimization, resulting reduction both consumption reactants generation waste products. In present study, reactivity NaHCO3 toward HCl SO2 was investigated temperature...
This perspective article aims to identify key research priorities make the waste-to-energy sector compatible with societal goals of circularity and carbon neutrality. These range from fundamental process engineering innovations socio-economic challenges. Three focus areas are highlighted: (i) optimization flue gas cleaning processes minimize gaseous emissions cross-media, (ii) expansion control intelligence meet targets for both material recovery energy recovery, (iii) climate neutrality,...
Life cycle assessment (LCA) is a powerful tool to identify direct and indirect environmental burdens associated with products, processes services. A critical phase of the LCA methodology collection representative inventory data for energy material streams related production process. In evaluation new emerging chemical processes, measured are known only at laboratory scale may have limited connection footprint same process implemented industrial scale. On other hand, in already established...
This study presents a systematic approach to process safety quantification within the early-stage evaluation of sustainable carbon capture strategies for hard-to-abate industrial emission sources. Reference post-combustion CO2 were analysed two different plants, differing each other in flue gas composition and scale. Results reveal substantial performance variations among alternative strategies, with amine scrubbing showing significantly higher risk due hazards associated toxic flammable...
Carbon capture and storage (CCS) is expected to play a significant role in the decarbonization of industry, especially "hard-to-abate" sectors where combination process heat-related CO2 emissions hinders alternative approaches such as deep electrification. However, non-negligible amount industrial emission sources consists small-sized plants or units. For instance, EU Emission Trading Scheme (ETS) registry shows that one fifth registered installations are very small with yearly lower than...
This study aims at providing a dataset for selecting the most suitable consolidant marble, limestone and lime mortar. Diammonium hydrogen phosphate (DAP), nanolimes (NL), ethyl silicate (ES) acrylic resin (B72) were compared. Application was performed by brushing in different amounts to investigate influence of product consumption. Effectiveness, compatibility, durability sustainability evaluated. DAP showed several advantages over alternative consolidants, terms both technical performance...
The operation of dry processes for acid gas removal from flue in waste-to-energy plants based on the use calcium hydroxide as a solid sorbent generates waste stream containing fly ash, unreacted hydroxide, and products its reaction with pollutants (HCl SO2). To date, fate is to be put into landfill absence commercially viable recycling approaches. present study investigates potential these residues CO2 sorbents looping process. Samples collected different were tested over multiple...

The failure of emission control systems in industrial processes undergoing regulations can cause severe harm to the environment. In this context, safety engineering principles be applied analyze process deviations and identify suitable barriers mitigate harmful emissions during critical events. However, selection, design, assessment proper may complex due several contingencies such as inability perform extensive field tests on under strict regulations. study, an approach is proposed couple...
The field of the conservation and repair built cultural heritage shows a growing attention towards environmental sustainability materials treatments used for projects. As standardized methodology that is widely adopted comparative evaluation construction building materials, life cycle assessment (LCA) can be usefully applied to if specific field-related issues on definition functional units reference flows are properly addressed. In present study, LCA quantify footprint four alternative...
This paper presents a study of identification and validation data-driven models for the description acid gas treatment process, key step flue cleaning in waste-to-energy plants. The removal line an Italian plant, based on injection hydrated lime, Ca(OH)2, abatement hydrogen chloride, HCl, is investigated. final goal to minimize feed rate reactant needed achieve required HCl performance, also reducing as consequence production solid process residues. Process data are collected during...
Acid gas removal is one of the main drivers operating costs in flue cleaning lines waste-to-energy (WtE) plants. In light updated technical and normative references, such as revised Best Available Technology reference document for waste incineration EU, plants are required to comply with increasingly lower emission limit values (ELV). case existing WtE plants, this requires selecting appropriate option among three alternatives: intensification current operations, installation additional...
