Multi-objective optimization of organic Rankine cycles for waste heat recovery: Application in an offshore platform
Pierobon, Leonardo; Nguyen, Tuong-Van; Larsen, Ulrik; … - In: Energy 58 (2013) C, pp. 538-549
This paper aims at finding the optimal design of MW-size organic Rankine cycles by employing the multi-objective optimization with the genetic algorithm as the optimizer. We consider three objective functions: thermal efficiency, total volume of the system and net present value. The optimization...

Optimal design of process energy systems integrating sustainable considerations
Lira-Barragán, Luis Fernando; Ponce-Ortega, José María; … - In: Energy 76 (2014) C, pp. 139-160
In this paper is presented a novel approach for designing sustainable trigeneration systems (i.e., heating, cooling and power generation cycles) integrated with heat exchanger networks and accounting simultaneously for economic, environmental and social issues. The trigeneration system is...
