Published by Elsevier B.V. under a Creative Commons license (http://creativecommons.org/licenses/by/4.0/). abstract: Process intensification is essential in exploring more energy-efficient processes, and key examples related to fluid separations are reactive distillation and hybrid distillation-pervaporation processes. This work will consider the reaction and separation of a general quaternary reactive system with a minimum boiling binary azeotrope AC, in a reactive distillation column where, given the thermodynamics limitations, further downstream separation is required. Low and high chemical equilibrium is considered for the reaction. For the downstream purification, both pressure swing distillation and a hybrid distillation-pervaporation process are considered. For each of the structures, their intensified equivalent dividing wall structures are also considered, including a hybrid reactive dividing wall system. It is shown that reactive distillation followed by a hybrid distillation-pervaporation system can save up to 24% energy compared to reactive distillation with pressure swing separation, and that the dividing wall column counterpart structures have lower production-based total annualised costs than the corresponding base systems. date: 2024-07 date_type: published publisher: ELSEVIER SCIENCE SA official_url: http://dx.doi.org/10.1016/j.cep.2024.109832 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2282877 doi: 10.1016/j.cep.2024.109832 lyricists_name: Sorensen, Eva lyricists_name: Tsatse, Aikaterini lyricists_name: Chia, Dian Ning lyricists_name: Duanmu, Fanyi lyricists_id: ESORE42 lyricists_id: ATSAT78 lyricists_id: DNCHI44 lyricists_id: FDUAN24 actors_name: Chia, Dian Ning actors_id: DNCHI44 actors_role: owner full_text_status: public publication: Chemical Engineering and Processing - Process Intensification volume: 201 article_number: 109832 pages: 19 citation: Duanmu, Fanyi; Chia, Dian Ning; Tsatse, Aikaterini; Sorensen, Eva; (2024) Optimal design and operation of reactive distillation systems and reactive dividing wall systems with pressure swing distillation and hybrid distillation-pervaporation.
