“…In subsequent operations, the crystals are separated from the remaining brine and then melted to result in purified water as the useful product. The various necessary processes are carried out so that the main heat transfer processes, that is, freezing and melting, are regenerative, resulting in very highenergy efficiency (Rice and Chau, 1997).…”

“…Cryoconcentration, which has been studied for desalination of sea water, has low energy costs for large-scale use (Rice and Chau, 1997). Cryoconcentration technology is well suited to food liquids such as milk whey, because of the negligible stress that this concentration technique exerts on whey ingredients.…”

“…Furthermore, according to Attia (2010), the cost of freeze desalination using an auto-reversed R-22 vapor compression heat pump is 50% lower than most efficient methods reviewed previously (Lara, Noyes, and Holtzapple 2008). Rice and Chau also elaborated the idea of using hydraulic refrigerant in freeze desalination plants, stating that freeze desalination is much more attractive than it has been in the past and should be reconsidered and compared with other means of desalination with regard to energy efficiency and other operating parameters (Rice and Chau 1997). Actual energy consumption using freezers is affected by different factors.…”

Options to develop tanning industries could be hindered even in the presence of huge leather industry raw materials due to the requirements of high-tech contaminant removal technologies, especially in developing countries. This study was initiated to investigate the efficiency of freeze desalination for Cr(VI) removal using refrigerators to generate fresh water. Synthetic solutions that represent major ion compositions of drinking water as well as deionized water to which known concentrations of Cr(VI) spiked into it, were added and frozen in a closed freezer unit. The effects of different parameters such as initial concentration, freeze duration, ice nucleation, fraction of ice volume, and influence of co-occurring ions were evaluated in relation to the quality of produced ice. The physicochemical characteristics of the produced meltwater were also evaluated. A high total water recovery of up to 85% was achieved in the experimental evaluation. Cr(VI) removal efficiency of up to 80% from simulated tap and 93 to 97% for deionized water spiked with Cr(VI) were found in this batch partial freezing. Freeze desalination was found to be relatively viable desalination technology in terms of quality of water produced, options on the use of cost effective refrigerants and technologies which could have a pertinent importance to save energy consumption of freezers.

Theoretical approach of freeze seawater desalination on flake ice maker utilizing LNG cold energy

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. Keywords:Freeze desalination; Flake ice maker; LNG cold energy; Dynamic modeling; Ice growth
