Special Issue Information

Dear Colleagues,

The thermodynamic optimization of the industrial systems deals with the application of the thermodynamic principles to evaluate and improve the performance of those energy systems, from the component level up to the complete process synthesis and optimization of chemical plants. The energy integration (pinch method) and the exergy methods are among the most common thermodynamic methods used in the diagnosis and optimization of energy systems. Those methods help to identify the sources of thermodynamic inefficiency and allow proposing means for minimizing energy consumption, while reducing waste generation and, consequently, the environmental impact. Meanwhile, optimization methods aid in determining the best configuration among the vast number of options that satisfy the predefined objectives and restrictions using different mathematical and computational techniques. This Special Issue aims to bring together a comprehensive selection of recently developed techniques used to evaluate the performance of thermodynamic systems. It is also conceived to aim the spotlight at new approaches proposed to assess not only efficiency, but also sustainability and economic attractiveness as decision criteria for future energy systems.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs).

A hybrid scheme integrating the current waste heat recovery system (WHRS) for a silicon arc furnace with plasma gasification for medical waste is proposed. Combustible syngas converted from medical waste is used to drive the gas turbine for power generation, and waste heat is recovered from the raw syngas and exhaust gas from the gas turbine for auxiliary heating of steam and feed water in the WHRS. Meanwhile, the plasma gasifier can also achieve a harmless disposal of the hazardous fine silica particles generated in polysilicon production. The performance of the proposed design is investigated by energy, exergy, and economic analysis. The results indicate that after the integration, medical waste gave rise to 4.17 MW net power at an efficiency of up to 33.99%. Meanwhile, 4320 t of the silica powder can be disposed conveniently by the plasma gasifier every year, as well as 23,040 t of medical waste. The proposed design of upgrading the current WHRS to the hybrid system requires an initial investment of 18,843.65 K$ and has a short dynamic payback period of 3.94 years. Therefore, the hybrid scheme is feasible and promising for commercial application. Full article
