STIG power plant is a competitive choice for commercial use because of its inherent characteristics and high efficiency. But if it was to be a marine propulsive engine, a fresh water supplying system should be provided for the heat recovery boiler. A two stage experimental reverse osmosis (RO) sea water desalination system which consist of an RO membrane and fine filter and super fine filter etc. is established. The experiments on the system and measurements of the desalination water quality indicate that the RO desalination system is suitable for marine STIG power plant. Some design and experimental problems and experimental results are presented and discussed in this paper.

<p></p><p>The growing population and energy demand, coupled with the depleting fresh water resources has resulted in great progress in sea water desalination (SWD) technologies. Nanopores of 2D materials like graphene and its structural analogs are the latest innovations in membrane technology for SWD. The performance of these novel atomically thin nanopores as seen from various experimental and theoretical studies is highly encouraging with reports of water permeability 2-3 orders of magnitude greater than the conventional reverse osmosis (RO). The potential for high efficiency and the low energy requirements of these nanopores for desalination has led to tremendous efforts in fabrication and commercialization. We present here a review of the very recent patents associated with the preparation of these nanopores, the process and the efficiency of SWD. </p><br><p></p>

Herein, we report on the performance of a hybrid organic-ceramic hydrophilic pervaporation membrane applied in a vacuum membrane distillation operating mode to desalinate laboratory prepared saline waters and a hypersaline water modeled after a real oil and gas produced water. The rational for performing “pervaporative distillation” is that highly contaminated waters like produced water, reverse osmosis concentrates and industrial have high potential to foul and scale membranes, and for traditional porous membrane distillation membranes they can suffer pore-wetting and complete salt passage. In most of these processes, the hard to treat feed water is commonly softened and filtered prior to a desalination process. This study evaluates pervaporative distillation performance treating: (1) NaCl solutions from 10 to 240 g/L at crossflow Reynolds numbers from 300 to 4800 and feed-temperatures from 60 to 85 °C and (2) a real produced water composition chemically softened to reduce its high-scale forming mineral content. The pervaporative distillation process proved highly-effective at desalting all feed streams, consistently delivering <10 mg/L of dissolved solids in product water under all operating condition tested with reasonably high permeate fluxes (up to 23 LMH) at optimized operating conditions.
