Novel supercritical CO2-Based Low-Carbon multigeneration System: Multi-Objective optimization for combined Power, Cooling, Heating, and desalination

Energy Conversion and Management X, Journal Year: 2024, Volume and Issue: 23, P. 100649 - 100649

The challenges posed by power shortages, hot climates, heating demands, and water scarcity on island platforms significantly impede productivity quality of life. Implementing a multi-energy supply system emerges as promising solution to address these issues. In this study, we propose, analyze, optimize novel multigeneration for cooling, heating, power, desalinated production, leveraging waste heat from nuclear plant. This innovative integrates recompression supercritical CO2 (sCO2) Brayton cycle, an Organic Rankine Cycle (ORC) with booster-enhanced ejector refrigeration cycle (BERC), absorber transformer (AHT) distillation unit, unit (HU). Harnessing energy cascading the efficiently recovers surplus generated sCO2 which serves multiple purposes: powering ORC generator additional generation, driving BERC user fueling AHT HU systems freshwater production respectively. system's performance is rigorously evaluated through thermodynamic exergoeconomic analyses, established validated models. Parametric analysis reveals crucial trends in respect eight key parameters. Additionally, single-objective multi-objective optimizations, utilizing weight coefficients approach, are conducted maximize efficiency minimize total product cost. Notably, importance balancing compressor pressure ratio optimal exergy or minimum cost underscored. Exergoeconomic optimization demonstrates substantial reduction (6.1% 1.59%) overall compared optimizations alone, while achieving (62.54%), (66.75%), sum products 10.02 $/GJ. Multi-objective optimization, treating all three objectives equally, yields impressive results, including 82.3%, 62.41%, 10.58

Renewable energy powered membrane technology: Impact of intermittency on membrane integrity

Desalination, Journal Year: 2024, Volume and Issue: 580, P. 117504 - 117504

Published: March 6, 2024

Directly coupled photovoltaic-powered nanofiltration/reverse osmosis is a good solution to brackish water desalination in remote areas. Intermittent operation of the system may cause physical membrane damage and loss integrity. The potential causes integrity during intermittency include sudden spontaneous restart process, frequent shut-down events, osmotic backwash (OB) cleaning with controlled permeate backpressure. A bench-scale crossflow powered by solar array simulator was used perform periodic fluctuation on filtration experiments that this case intermittency. wide range feed pressure rising speeds (0.17 2 bar/s) start-up up 1000 additional backpressure 4 bar enhance OB were applied. Results show no significant performance deterioration observed when increase velocity increased bar/s, event number implying robustness NF/RO membranes cleaning. When increasing 2–4 both observed. This demonstrates reliability towards fluctuation, intermittency, directly if avoided.
