evaporator

[asesor]

Need to build a single phase evaporator ( Tray like?) for saltwater disposal. Have unlimited access to gas and inexpensive diesel. The capacity should be between 500 to 800 barrels per day.
Any ideas?

I am working on a similar problem, a combination snow melter evaporator to dispose of the water containing high amounts of salt and deicing chemicals. From what I have learned the most efficient type of burner for these applications is a submerged combustion burner, fuel and air are injected under pressure into a combustion burner tube following ignition and subsequent combustion hot combustion gases are then forced through holes at the bottom of the burner assembly which is submerged in the fluid to be heated hot combustion gases then rise up through fluid in the tank. With a little engineering analysis going into the design and with some other trickery or black magic -like forcing a helical flow of fuel and air through the combustion chamber, using pulsed combustion, or a manifold burner design the system will achieve a high degree of thermal efficiency, nearly perfect. Both the US and Canadian departments of energy have endorsed submerged combustion technology as being the most efficient technology for hot water production and other process heating. If you go to

http://www.eclipsenet.com

you can find out more about submerged combustion burners, you can also request a free CD that is loaded with engineering data, application data, tech notes and an engineering design and analysis section that will be useful in designing your system or for other process heating applications. I am somewhat new to the group so if I have committed a faux par in mentioning eclipse I appologise, I have no connection to them other than knowing they put out quality technical informatioin.
