Additional thought ... while it's open, carefully measure the to the top of each heater and put a run of weld or a mark on the tank and transfer that to the sight tube before you insulate.

It will come in handy at some point in the future.

Thanks Julian :)

Good plan with the heaters, I'll measure that, particularly the cone mounted one as you can't tell where is sits now, let alone with insulation. 

Hmmm, Dick might read this and shake his head, I'm sure he's probably already told me about the de-mething options.  :)

I've head or read so many different ways of doing it, its hard to figure out whats what. 

Do you all "bubble" or is the "inverted spoon while boiling it out" a sufficient alternative?

What about the pressure drop evaporator, is that instead of bubbling?

Or letting air into the venturi during the de-meth stage, is that an alternative to bubbling?

I like the idea of trying to combine the "air in through venturi "and "spoon fountain" do help with the distillation.  Would I still need to bubble after this??

Sorry for all the questions.  Perhaps I should go over the wiki again.

I tend to dry oil with the venturi, demeth with the venturi and also air bubble for 24h from hot just to drive off any trace Methanol left.

That said any form of spraying or diffusing will also help.  Your call :)

Should be about this pm but, as always, give me a ring first. We can discuss bumbling ect then. I same you will be fitting the safety stop so that the heaters can only be switched on when oil is over the heaters? Remind me to have a look for a working pressure switch.

My process in detail is as follows ...

Poor quality oil/whites go into an open top tank through a mesh for melting, rough drying and separating.

Good oil and liquid oil from the above, go into a settling/storage tank through a filter.

Oil is then dried the in the processor with the venturi and condenser.

2 stage conversion process.

7% wash followed by an acid pump wash and water pump wash and then dried in the processor with the venturi and condenser.

Transfer to  settling tank and bubble overnight.  Leave to settle.

Transfer to a second settling tank via a dry wash tower.  Leave to settle.

Transfer to outside bulk storage and then into the car via a 1µ  filter.



I think your best bet is to build a system that will do all known functions and then find which process best suits you.

Right you are then, I'm trying to run before I can walk. 

I've been thinking about mounting it all and I think I've had a cracking idea.  I don't want it in the lean to out the back for security reasons especially with all the copper in it, but I know I should for safety reasons.  I'll only need it outside for a day or two once a month, so.......

I'm going to buy a small trailer, and mount it all on there, containment and all.  We have just the thing (although I'll have to buy another one as I'm sure dad doesn't want me ruining this one) but we often wheel the thing from in the garage to where the lean to is, be hand with no problems. 

Best of both worlds.  Stored more securely in the garage, where it can be worked on, then wheeled around the back, connected to the vent and used there when needed.   Win Win!!!!   I think the inlaws even have one they dont want :)

If your going to mount it on a trailer, then it would probably be worth earthing the body of the processor. It's probably a good thing to do anyway, but if it's sat on the floor, at least any static build up has a route out. On a trailer, it hasn't, and could potentially cause a spark.
Maybe just take an earth from the drum, into the earthlead, but I'm not sure about that. I put a ground spike in and took a wire to it from a clamp on one of the pipes.

Another thing to consider if mounting on a trailer is stability, you don't want around 300kg wobbling about with a high center of gravity.

Also the height of the whole will be increased adding to the problem.

Yeah, it'll certainly need some legs to drop down while in use, a vent connection, and the earths is a great idea. 

Been to see Dick, lots of ideas and parts from my trip :)  :)  I'm excited to get going with it.  Need a trailer now though.

I toyed with the idea of making my processor mobile by building it to a size that would fit on a pallet, but in the end it seemed easier to put a door on the shed! As for demething, if nobody else has already told you this, it makes a big difference to put a heat exchanger before the condensor. The hot side of the heat exchanger is the vapour pipe on its way to the condensor and the cold side is the air return pipe from the bottom of the condensor to the Venturi. I was skeptical about the benefit of heating the air going into the Venturi because I thought that the oil flow was so hot anyway that hot or cold air was neither here nor there, but on the advice of others on the forum I added it anyway and I reckon it doubled the efficiency of my demething. That condensor you've built is way over specified for 3kw, and none the worse for that!

Julian,

I can't get the thumbnail thingy to work on the wiki page, I'm sure its something I'm doing wrong, any chance you could have a look at how I've put it on the page?

You had the file extension as png when it was a jpg.

I wondered if png was the problem, I tried jpg as all the other links you showed me were jpg, but I still couldn't get it to work. 

Thanks for fixing it.

The wiki can use several different file types, what you call up on the page just has to match what you've uploaded.

If there's any obscure type you want to use, give Tony a shout and he can magically modify things.
