“…For VRHP-DCED, sequence V provides the lowest steam costs, and four sequences (I, II, III, IV) are much better in terms of annual cost than CED sequences, and four sequences (I, II, III, IV) are better for environmental efficiency. However, II' and IV' made VRHP-ICED more environmentally efficient than CED sequences and I,' IV,' and VI' sequences [17].…”

“…Several HPAD concepts have been studied, each one giving the maximum power saving only at specific conditions [21][22][23]. Distillation technology is used for a wide range of separation tasks, involving different species, and the assessment of the most appropriate HPAD strategy for the given task can be a topic of great concern for the engineers.…”

Tritium permeation constitutes a key issue for the future EU-DEMO, especially in the Breeding Blanket (BB) where fusion energy must be delivered to the Primary Heat Transport System (PHTS) and where tritium must be bred. Currently, the mitigation strategy of the tritium permeation from BB into primary coolant is based on the adoption of anti-permeation barriers and on the operation of the Coolant Purification System (CPS). This system must ensure a tritium removal rate from the primary coolant equal to the BB permeation rate at a target tritium-specific activity inside the PHTS. In the case of the Water-Cooled Lithium Lead (WCLL) BB, water distillation was selected as the most promising technology for the primary coolant detritiation due to its intrinsic simplicity and safety. Nevertheless, power consumption was recognized as a relevant concern. For this reason, the present work aims at investigating possibilities to reduce power consumption of the water CPS implementing Heat Pump-Assisted Distillation (HPAD) concepts. To do this, a review of the HPADs developed in the chemical industry was carried out, and the best options for the water CPS were identified based on qualitative considerations. Then, a quantitatively assessment of the best solution in terms of power consumption and tritium inventory was performed with the commercial numerical tool Aspen Plus. Finally, the Mechanical Vapor Recompression (MVR) concept was recognized as the most promising solution, ensuring a power saving of around 80% while keeping a limited tritium inventory.

“…The composition of B (high-boiling point) is relatively low in the azeotropic composition for some binary azeotropes separated using intermediate entrainers. ,, Therefore, the feed contains a high concentration of light component B when the feed composition deviates from the azeotropic composition. Indirect CED is more suitable under this condition.…”

“…Intermediate-boiling entrainers are better than heavy-boiling entrainers since they avoid high-pressure steam usage and consume less energy during entrainer recovery. Numerous studies have focused on the separation of azeotropic mixtures using intermediate-boiling ED entrainer based on various aspects: thermodynamic analysis, , simulation and optimization, , heat integration, , and control . Modla conducted a study on the separation of binary mixtures using three distillation schemes: conventional distillation, heat integration, and dividing wall column with an intermediate-boiling entrainer.…”
