Direct Optimization for Cycle Working Fluids Using a Thermodynamic Generalized Fluid Approach

SolarPACES Conference Proceedings
Fluid blends as working fluids in solar thermal power cycles have been shown to promise an even higher efficiency than pure fluids. Rather than exploring specific blends, we propose an approach in which we directly optimize for a working fluid ...

Benchmarking Thermodynamic Models for Optimization of PSA Oxygen Generators

J, 2023
In this review, the authors conducted benchmarks for three thermodynamic models to analyze PSA-based medical oxygen concentrator (MOC) systems to allow for optimization and operational flexibility. PSA oxygen generator plants are good medical-grade oxygen sources, a crucial tool in healthcare from the primary to the tertiary level.

A generalized disjunctive programming model for multi-stage compression for natural gas liquefaction processes [PDF]

E3S Web of Conferences, 2023
The primary driver of operating costs in natural gas processes is the energy consumption of the compression system. Multistage compression configurations are commonly employed and hence play a vital role in optimization of natural gas processes.
