Analysis of integrated calcium looping alternatives in a cement plant

Calcium looping is a promising post-combustion CO2 capturing technology, highly compatible with the cement industry, one of the major industrial sources of CO2 emissions. Limestone, a raw material for clinker, forms lime, a calcium looping adsorbent. Thus, it is possible to maximize the synergies between a cement plant and a calcium looping unit by establishing an integrated configuration. Nevertheless, the int...

Sustainability Assessment of 2G Bioethanol Production from Residual Lignocellul...

ABSTRACT: The development of sustainable biofuels can help to reduce the reliance on fossil fuels and mitigate the impact of climate change. This study analyzes bioethanol production from agro-forestry residual biomass, namely eucalyptus residues and corn stover. The study includes process simulation using Aspen Plus software, followed by economic analysis and life cycle assessment (LCA) with the help of SimaPr...

Correction: Correia et al. Sustainability Assessment of 2G Bioethanol Productio...

Error in Table: In the original publication [1], there was a mistake in Table 8 as published. The presented cost of purchased equipment and Total CAPEX cost shall not differ between the two scenarios. The purchased equipment cost and Total CAPEX cost should be, for both scenarios, 21.35 and 75.66M€, respectively. The corrected Table 8 appears below. The authors state that the scientific conclusions are unaffect...

Decision-making based on sustainability analysis using GREENSCOPE

Current economic and environmental pressure encourages companies to invest and reform processes in a sustainable way. However, the decision on the best sustainable investment in a given industry may not be as straightforward as given by the independent economic and environmental indicators. Analyzing such indicators for investment in process alternatives is a complex multi-objective decision-making process. Man...

Sustainability analysis of a solar-driven calcium looping plant for thermochemi...

Sustainable development is essential to ensure that future generations enjoy the same or better standard of living as today's society. Clean energy will play an important role in this. Concentrated solar power is one of the cleanest ways to harness solar power and convert it into useable energy like electricity. However, due to the intermittent nature of solar power production, concentrated solar power needs to...

Modeling the deactivation of CaO-based sorbents during multiple Ca-looping cycl...

A novel model is presented for the estimation of natural CaO-based sorbents carbonation reactivity decay during Calcium Looping carbonation-calcination cycles. The model consists of a cyclic framework of two sub-models, the Overlapping Grain Model and the novel proposed modified Rate Theory for the Pore Size Distribution model. The model was implemented in gPROMS ModelBuilder (R) and parameter estimation was us...

Fatty acid content in biomasses: state-of-the-art and novel physical property e...

In line with the growing environmental awareness developed along the last decades, modern societies are urged to evolve into sustainable economics where the reuse of organic wastes represents the key feedstock for a green transaction. The oil phase obtained from different biomasses has the potential to be a source of food supplements, medicines, cosmetics, or feedstock for biofuel production. In the present wor...
