Odsalanie
Woda jest najbardziej dostępną substancją na morzu, lecz sól i zanieczyszczenia czynią ją niezdatną do większości zastosowań na statkach. Wyparowniki wody słodkiej produkcji Alfa Laval pozwalają czerpać gospodarcze korzyści ze wspomnianego zasobu oraz zapomnieć o drogiej i niskiej jakości wodzie zbiornikowej.
Smarter ways to fresh water
Alfa Laval pioneered the compact and cost-efficient production of fresh water. Over 50 years ago, we introduced thermally driven freshwater generators with dual-plate-pack technology. These were not only smaller than shell-and-tube installations, but also far less sensitive to scaling.
Today we’ve further developed our multi-effect concept, enabling vacuum distillation within a single plate pack. Our revolutionary AQUA freshwater generator, which houses the vacuum in the plate pack itself, contains three-in-one titanium plates on which evaporation, separation and condensation all occur.
Reducing energy use and emissions
A major advantage of AQUA’s three-in-one plate technology is the fact that it cuts seawater requirements in half. This allows smaller pipes and pumps to be used, which means a reduced initial investment, easier installation and lower energy consumption – with lower CO2 emissions as a result.
But the energy efficiency is hardly limited to AQUA. Where larger volumes of fresh water are needed, our multi-effect plate MEP desalination plant typically consumes just 1.3–3.0 kWh/m3, thanks to an optimized pump configuration and a frequency-controlled motor on the seawater pump.
