Dewatering with dehumidifier?

Postby curdy » Wed Oct 29, 2008 12:12 pm

Hey guys, I'm looking for some help with drying out my WVO. I have a 350 gallon cone bottom tank that I'll be looking to dry 250 gallons of WVO at a time in. I have a pump set up to it and in line heating elements.

My plan is to install some spray nozzles inside to atomize the WVO as it cycles. Then, I was going to cut 2 holes in the top and attach duct type hoses to and from a dehumidifier (supply and return) and a drain hose for the water. Having the system enclosed would continuously cycle the air through the dehumidifier (humid air in, dry air out).

Will this work?

I live in the SE PA area where its pretty humid, so I thought this made sense.

Thanks in advance!

It might work but its a lot more complex than simple settling, and would still take a lot of time.

Dehumidifiers are only good for reducing the humidity from +95% to ~70% and they consume a lot of energy.
Any sort of evaporative drying leaves crud in the oil.
There are much better ways.
Do a Google search for "cold upflow"
