Passarell VES Process and Applications

 

WDI Applications

WDI Technology Characteristics

The anticipated low energy cost and low carbon desalination process separating procedure for water and dissolved solids in large and small volumes leaving fresh water and marketable salts in separate forms.

 

The process that eliminates the practice of returning wastewater to the supply source and the production of a commercial marketable product

Salt elements concentrated through nonsupport of mass weight in a vapor atmosphere.

Solids discharge controlled from the system in wet or dry condition reducing operational labor.

This system operates on a thermal configuration, any thermal energy generation such as natural gas, electricity, solar, cogeneration, and wind power (etc).  Unique as the total vapor produced is recycled with the only loss of thermal energy to the local environment’s ambient conditions.

The process is designed and engineered to eliminate scaling in the vaporizing apparatus. A high impact polymer can be used in the plate heat exchanger to eliminate scaling of the plate heat exchanger.  Operates with no mechanical moving parts and chemicals are not needed for operation.

Requires the smallest footprint of any desalination system, operates without chemicals, lowest energy requirements of all desalination processes and eliminates the noise factor.

Flow description

 

This process provides a method which, after the system reaches thermal operating temperatures and pressures, requires only relatively small amounts of additional heat energy to sustain the desalination process. The heat energy used for operation is vapor.  The entire vapor generated in the operation is sustained for maintaining the thermal energy used in the operation. A small amount of vapor energy is lost to the ambient environment and must be generated for its replacement.

 

(1)  Source water (seawater) enterers the system and is heated in the plate heat exchanger by the processed heated fresh water leaving the desalination plant. 

 

(2)  The source water moves from the plate heat exchanger to the vapor chamber (B) in which the pressure and temperature of the chamber is held to 212+°F temperature, a few degrees higher than the source water entering the chamber.

 

 (3) The boiler or steam generator’s (C) requirement is to maintain the 212+°F temperature in the vapor chamber. The plus being sufficient thermal energy to lure and increase the 212° of the in coming seawater to a point of vaporization and still maintain the original 212+°F  in the vapor chamber.  When the 212° seawater entering is activated by the greater sum of the BTUs (degrees) above the 212° in the 212+° vapor, the 212° vapor would equalize the greater sum of energy and vaporize the seawater.

 

(4) The distribution block, channels the steam and seawater through the seawater distributing tubing in to the vapor chamber.

 

(5)  The seawater distributing tube distributes the seawater over the silicone cone surface in a thin film.

 

(6)  The seawater in the vapor chamber which contains the feed tube, silicone coated cone and the area where the heavier elements separate from the water and fall into the sump.

 

(7)  Sump, salt collection area.

 

(8)  Secondary chamber is where the vapor from the primary chamber is metered out to 212° temperature or 14.6+ psi prior to traveling to the plate heat exchanger.

 

(9) This is the feed pipe to the plate heat exchanger.

 

(10) This is where the product water leaves the desalination plant through the plate heat exchangers.

 

1.     Source inlet water enters plate heat exchanger.

2.     Water from the plate heat exchanger moves to the vapor chamber where the temperature in the vapor chamber must be held 212 + °F degrees temperature.

3.     Boiler or steam generator feed to vapor chamber.

4.     Steam and supply line distributor.

5.     Supply feed to silicone cone.

6.     Vapor chamber must maintain 212 plus degrees Fahrenheit.

7.     Salt collection sump.

8.     Secondary chamber.

9.     Feed pipe to plate heat exchanger to 12° 212°F before entering plate heat exchangers.

10.  Product water exits from plate heat exchanger.
