Exergy Analysis of Multicomponent Distillation Systems for Efficiency Ranking
Chemical Engineering Transactions, 2012 In this paper a complex methodology is tested and verified to select the most adequate energy integrated distillation structure for a specific separation task. Exergy, economic and environmental analyses are applied to select the most efficient rectification structures for separation of quaternary hydrocarbon mixtures.

Exergy efficiency of ammonia production
, 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 ...
