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 ...
2024Thermodynamic bounds on time-reversal asymmetry
Quantifying irreversibility of a system using finite information constitutes a major challenge in stochastic thermodynamics. We introduce an observable that measures the time-reversal asymmetry between two states after a given time lag. Our central result ...
College Pk2023Information Spectrum Converse for Minimum Entropy Couplings and Functional Representations
Given two jointly distributed random variables (X,Y), a functional representation of X is a random variable Z independent of Y, and a deterministic function g(⋅,⋅) such that X=g(Y,Z). The problem of finding a minimum entropy functional representation is kn ...
2023Recognizing the life and scientific contributions of a pioneer in solar thermochemistry: Prof. Aldo Steinfeld
Professor Aldo Steinfeld's contributions to the fields of solar thermochemistry and energy conversion are extensive and impressive. His work has greatly contributed to the ongoing transition from fossil to renewable fuels. We, his former doctoral students ...
PERGAMON-ELSEVIER SCIENCE LTD2023Techno-economic and environmental analysis of methanol and dimethyl ether production from syngas in a kraft pulp process
The conventional configuration of a pulp mill, in which black liquor is concentrated and burnt, is compared to the upgrading gasification routes for methanol (MeOH) or dimethyl ether (DME) co-production. To this end, various exergy-based and environmental ...
PERGAMON-ELSEVIER SCIENCE LTD2022Exergy 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 ...
2022Atmospheric biogenic volatile organic compounds in the Alaskan Arctic tundra: constraints from measurements at Toolik Field Station
The Arctic is a climatically sensitive region that has experienced warming at almost 3 times the global average rate in recent decades, leading to an increase in Arctic greenness and a greater abundance of plants that emit biogenic volatile organic compoun ...
COPERNICUS GESELLSCHAFT MBH2022Techno-Economic and Environmental Assessment of Ammonia Production From Residual Bagasse Gasification: A Decarbonization Pathway for Nitrogen Fertilizers
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 ...
