Process modeling and integration of hydrogen and synthetic natural gas production in a kraft pulp mill via black liquor gasification
François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos
The black liquor gasification integrated to chemical plants has shown potential for reducing the process irreversibility and promoting the decarbonization of this industrial sector. In the integrated chemical plants proposed in this work, the purpose is co ...
2023Fluctuations of entropy production of a run-and-tumble particle
Daniel Maria Busiello, Amos Maritan, Deepak Gupta
Out-of-equilibrium systems continuously generate entropy, with its rate of production being a fingerprint of nonequilibrium conditions. In small-scale dissipative systems subject to thermal noise, fluctuations of entropy production are significant. Hithert ...
AMER PHYSICAL SOC2023Coordination of protein synthesis and degradation in mammalian cells
The cellular protein levels are determined by protein synthesis and turnover rates. Two processes are involved in the proteome's turnover in proliferating cells: protein degradation and dilution. In theory, maintaining the cellular proteome concentration, ...
EPFL2023C2CAplus: A One-Pot Isothermal Circle-to-Circle DNA Amplification System
Sebastian Maerkl, Laura Sophie Grasemann
Rolling circle amplification (RCA) is a widely used DNA amplification method that uses circular template DNA as input and produces multimeric, linear single- or double-stranded DNA. Circle-to-circle amplification (C2CA) has further expanded this method by ...
Washington2023Swiss dams: Overview of historical development
With more than 220 large dams in operation, compared to its surface of some 41ʹ000 km2, Switzerland has a very large fleet. They were erected to meet various economic and protection needs. Their main assignments concern the storage of water for later use, ...
CRC Press/Balkema2023Techno-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 LTD2022Integrated production of chemicals and fuels in the pulp industry: techno-economic and environmental analysis of black liquor gasification-based processes
François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos
The pulp and paper sector is classified as an energy intensive activity and several efforts are being made to mitigate its atmospheric emissions, improve the recovery of residual heat and capitalize on its byproducts. The black liquor (BL) is a byproduct o ...
2022Luminescent and electronic properties of perovskite solar cells
Perovskite solar cells show great promise to serve as an alternative for traditional silicon-based solar cells, however several problems present obstacles for their commercialization. Standard perovskite cells contain lead, which is toxic to humans and har ...
EPFL2022Exergy and environmental analysis of black liquor upgrading gasification in an integrated kraft pulp and ammonia production plant
Daniel Alexander Florez Orrego
The black liquor is a byproduct of the kraft pulping process that contains more than half of the exergy content in the total woody biomass fed to the digester, representing a key supply of renewable energy to the pulping process. In this work, the conventi ...
