We presented economic,
energy, exergo-economic, and environmental
analyses and multiobjective optimization (MOO) of seawater reverse
osmosis (RO) desalination systems with boron restrictions. Exergo-economic
unit cost for flows and exergy destruction for components were included.
Life cycle assessment (LCA) principles with the contributions of construction
and operating were introduced. An improved augmented ε-constraint
method was adopted for solving the MOO problems. Unnecessary iterations
were avoided by bypass parameter. Results showed that the Pareto-solution
with a weighting of 0.4 could provide good performances for all objective
functions. The CO2 emissions reduction of 9.0% could be
achieved, while the water cost is increased by 3.3%. Fixed cost dominates
EUC. The environmental impact of construction is neglectable, while
electricity consumption accounts for the largest share of CO2 emissions from 93.4% to 97.8%. The details of energy utilization
for components, the irreversibility, and equipment cost assigned to
the streams are analyzed by using exergy and exergo-economic analyses.
The overall emergy-based exergo-environmental performances of the
systems are range between 81.5% and 84.6%. Both the component and
exergy destruction related ecological emergy rates need to be improved.
