Decarbonizing the fertilizers sector: an alternative pathway for urea and nitric acid production
François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos
In order to alleviate the environmental impact that nitrogen fertilizers production is responsible for, several efforts have been addressed to incentivize the partial or total decarbonization of the supply chains of ammonia and its derivatives. The decarbo ...
2024Comparative Exergy and Environmental Assessment of the Residual Biomass Gasification Routes for Hydrogen and Ammonia Production
Daniel Alexander Florez Orrego
The need to reduce the dependency of chemicals on fossil fuels has recently motivated the adoption of renewable energies in those sectors. In addition, due to a growing population, the treatment and disposition of residual biomass from agricultural process ...
2023Integrated production of urea and nitric acid in the pulp industry: techno-economic and environmental analysis of black liquor gasification-based processes
François Maréchal, Daniel Alexander Florez Orrego, Shivom Sharma, Meire Ellen Gorete Ribeiro Domingos
The pursuit of alternative energy sources for the nitrogen fertilizers sector has recently earned renewed interest due to increasing concerns regarding the world dependence on non-renewable energy resources and also motivated by the more stringent environm ...
2023Comparative Exergy and Economic Assessment of Fossil and Biomass-Based Routes for Ammonia Production
François Maréchal, Daniel Alexander Florez Orrego
Due to the increasing concerns about the marked dependence on fossil resources and their intrinsic economic uncertainty, as well as motivated by more stringent environmental regulations, the pursuit of alternative energy resources for the synthetic fertili ...
Silesian University of Technology2023Exergy and economic assessment of renewable electricity generation from sugarcane straw for improved efficiency of sugarcane biorefineries
This work focuses on the revamp of existing sugarcane biorefineries and cogeneration units by using those byproducts, aiming to increase the selling of surplus electricity. The analysis allows identifying potential improvements in the sugarcane cogeneratio ...
2022Incremental financial analysis of black liquor upgraded gasification in integrated kraft pulp and ammonia production plants under uncertainty of feedstock costs and carbon taxes
In this work, the conventional scenario of the black liquor (BL) concentration and combustion is compared with the BL upgrading gasification process for ammonia production. The chemical processes synthesis, modeling and simulation are performed by using As ...
Elsevier2022The effects of previous summer drought and fertilization on winter non-structural carbon reserves and spring leaf development of downy oak saplings
Xiaoyu Wang, Yue Yang, Peng He
It is still unknown whether the previous summer season drought and fertilization will affect the winter non-structural carbohydrate (NSC) reserves, spring leaf development, and mortality of trees in the next year. We, therefore, conducted an experiment wit ...
FRONTIERS MEDIA SA2022Techno-economic and environmental assessment of ammonia production from residual bagasse gasification: a decarbonization pathway for nitrogen fertilizers
Daniel Alexander Florez Orrego
This work evaluates the potential to produce synthetic nitrogen fertilizers by using sugarcane bagasse gasification in the São Paulo state, Brazil, aiming to increase the economic revenues and to decarbonize a chemical sector traditionally based on natural ...
2021A study on synergies of combined pulp and fuel production
François Maréchal, Tuong-Van Nguyen, Julia Granacher, Erina Clare Mcdonald
To limit climate change by reducing global greenhouse gas emissions, a transition away from fossil fuels is required. Biofuels represent a promising low carbon alternative for sectors that are hard to electrify, such as aviation. The integration of bio ref ...
2021Sugarcane bagasse and vinasse conversion to electricity and biofuels: an exergoeconomic and environmental assessment
Daniel Alexander Florez Orrego
Biomass conversion into either electricity or biofuels requires various energy intensive processes that may drastically affect its technical and environmental competitiveness against their non-renewable counterparts. Therefore, in this paper, a comparative ...
