Abstract
In this work, a novel concept in freeze desalination (FD) was introduced. Nowadays the total
liquefied natural gas (LNG) production capacity has reached 290 Megatons per year. Its
enormous cold energy released from re-gasification can be used in the freeze desalination
process to minimize the overall energy consumption. A process of FD on flake ice maker
utilizing LNG cold energy was designed and simulated by HYSYS software. An ice bucket on
flake ice maker was chosen as seawater crystallizer mainly due to its continuous ice making and
removing ice without heat source. A dynamic model of the freezing section has been developed
and simulated through gPROMS software. The results show that the consumption of 1 kg
equivalent LNG cold energy can obtain about 2 kg of ice melt water. In addition, it is shown that
the power consumption of this LNG/FD hybrid process is negligible.
