A desalination system that can comprise an inlet, an optional preheating stage, multiple evaporation chambers and optional demisters, product condensers, a waste outlet, one or more product outlets, a nested configuration that facilitates heat transfer and recovery and a control system. The control system can permit operation of the purification system continuously with minimal user intervention or cleaning. The desalination system can operate with any number of pre-treatment methods for descaling, and with degassing systems to eliminate or reduce hydrocarbons and dissolved gases. The system is capable of removing, from a contaminated water sample, a plurality of contaminant types including microbiological contaminants, radiological contaminants, metals, and salts.

A liquid desalination, distillation, disinfection, purification, or concentration system by repeatedly re-using thermal energy is provided. Thermal heat source can be solar, fossil fuel, or low grade heat discharged from industrial systems. Multiple thermally insulated and isolated stages of vaporization-condensation chambers can be connected to enhance production yield. Vapor is generated by direct heating of liquid and flash evaporation. Vapor generated is condensed in condenser cooled by intake liquid. Counter circulating intake liquid will be heated by released latent heat from vapor. Externally provided thermal energy will accumulate and be re-used in the system. Vaporization and condensation process will be continuously re-cycled to enhance production yield. The system can be configured to support flexible deployment in various configurations and in different locations, including direct floating installation on water surface.

The present invention relates to vapour-solids separations, and in particular provides a process for the separation of a stream comprising vapour and a stream comprising solids from a stream comprising vapour and solids using a separation vessel, said separation vessel having: a. a first inlet for the stream to be separated, b. a liquid outlet, c. a vapour outlet, d. a demister located on the vapour outlet, and e. a second inlet by which liquid can be passed to the demister said process comprising (i) passing the stream comprising vapour and solids through the first inlet and in to the separation vessel, (ii) recovering from the vapour outlet a vapour stream which comprises vapour from the stream comprising vapour and solids and which vapour stream has passed through the demister in the separation vessel, (iii) passing to the separation vessel, via the second inlet, a first liquid stream which contacts the vapour stream in the demister, and (iv) recovering from the liquid outlet a second liquid stream which comprising the solids from the stream comprising vapour and solids, and liquid from the first liquid stream.

Embodiments of the invention provide systems and methods for water purification and desalination. The systems have a preheater, a degasser, multiple evaporation chambers with demisters, heat pipes, and a control system, wherein the control system permits continuous operation of the purification and desalination system without requiring user intervention or cleaning. The system is capable of recovering heat from each distillation stage, while removing, from a contaminated water sample, a plurality of contaminant types including: microbiological contaminants, radiological contaminants, metals, salts, volatile organics, and non-volatile organics.

The invented system used in wet cooling tower, restore outlet fog of cooling tower into collection basin and consequently cooling water cycle. This invention consists of three main components; pump and its pertaining piping, waterfall and micron fog eliminator. In the first stage, the air containing fog is passed through a waterfall before exhausting. This action causes some portions of fog to condensate and fall down, remaining droplets of the fog grow and together with air cross the fog eliminator blades. Fog's droplets are entrapped between blades, leave the air, and restore to the tower. Therefore, humidity of exhausted air from tower will be effectively reduced.
