Abstract: Desalination plants based on Mechanical Vapour Compression (MVC) technology are inherently the most thermodynamically efficient. The thermodynamic efficiency of the MVC process is derived from the application of the heat pump principle. A single unit of a two-effect MVC desalination pilot plant of 50 m 3 /day capacity has recently been commissioned at Trombay, Mumbai. The desalination unit is very compact and unique in the seawater desalination technologies and is being operated by using electricity only. Horizontal tube thin-film spray desalination evaporators are used for efficient heat transfer. It is suitable for a site where feed water is highly saline and condenser cooling water is absent, and where a thermal heat source is not available. The unit produces high-quality water, nearly demineralised (DM) quality directly from seawater. There is no need for a polishing unit and product water can be used directly as make-up of boiler feed and for other high-quality process water requirements in industry. This paper includes the design and highlights the technical features of this unit.
TL;DR: In this article, the utilization principles, applications and problems of solar and nuclear energy in desalination are respectively summarized and discussed with emphasis, and other alternative energies such as wind, hydro-energy and ocean energy are also presented.
TL;DR: In this paper, a single-effect mechanical vapor compression (MVC) desalination system using water injected twin screw compressors is investigated. And the specific power consumption and the specific heat transfer area of the MVC system are then analyzed based on these characteristics.
TL;DR: In this paper, a hybrid MSF-MVC desalination system is proposed, and a parametric study was carried out to study the effects of MVC brine temperature and temperature drop across MVC stage on system performance in terms of specific power consumption, pressure ratio, feed to distillate ratio, specific heat transfer area, distillation product and exergy destruction.
