Tandem Electrolysers for High‐Efficiency CO2‐to‐Acetate Conversion Driven by Full‐Spectrum Solar Energy

open access: yesCarbon Energy, EarlyView.
A full‐spectrum solar‐driven tandem electrolysis system enables efficient CO2‐to‐acetate conversion by spectrally splitting sunlight and coupling high‐temperature SOEC CO2‐to‐CO electrolysis with ambient CO reduction. The integrated design achieves a solar‐to‐acetate efficiency of 15.8%, demonstrating effective energy‐quality matching for solar carbon ...

Exergy efficiency of ammonia production

open access: yes, 2018
© 2018 eceee and the authors, Stockholm. The chemical industry is responsible for roughly 6 % of global primary energy consumption and global greenhouse gas emissions, as well as a key fossil-fuel user (Cullen and Allwood 2010). Material and energy efficiency are the focus of industrial and policy decision-makers but are often pursued as separate ...

An exergy approach to efficiency evaluation of desalination [PDF]

open access: yesApplied Physics Letters, 2017
This paper presents an evaluation process efficiency based on the consumption of primary energy for all types of practical desalination methods available hitherto. The conventional performance ratio has, thus far, been defined with respect to the consumption of derived energy, such as the electricity or steam, which are susceptible to the conversion ...

A Methodology to Integrate Closed‐Cycle Heat Pumps into Batch Distillation Columns

open access: yesChemie Ingenieur Technik, EarlyView.
Batch distillation often cannot use vapor recompression due to contamination risks in food and pharma. This study proposes a design for integrating closed‐loop heat pumps using natural fluids. Results show significant energy savings, offering a sustainable alternative to traditional setups.

Impact of Distillation Column Design on Potential for the Integration of Mechanical Vapor Recompression

open access: yesChemie Ingenieur Technik, EarlyView.
Mechanical vapor recompression integration in distillation is analyzed, focusing on feed preheating and column pressure drop. Binary methanol–water and benzene–toluene separations are studied to identify optimal designs, which are further assessed in a bioethanol vacuum distillation sequence regarding energetic, ecological, and economic performance ...
