Two drum processor?

[K.H]

It seems to be far removed from my set up in the picture now and the two dont seem to fit,the idea of things like a 240lpm pump mean an eductor would be a backward step not an upgrade and process times are 15 mins not 1 1/2 hours,it sort of reads 240lpm pump= 1 1/2 hours if you see what im getting at?,has anybody got another pic more suitable and maybe move the existing down to the upgrades
And why would anybody want to convert a two drum set up into a GL?  ,i always view them as an alternative,i could suggest that a GL could also be converted,a nice wash tank to keep those HMPE,S away
On the eductor theme - with a lot of people moving to two stage it might be an idea to say that they are only a viable upgrade on single stage reactions as they only work with one set level,any views on that?
OH and BASIC? you would,nt call it b*****dy BASIC if you saw me struggling to build it!,at the BBB instead of the water washers corner there will now be a BASIC corner which will be ME and MY Barrell of beer! HIC

LOL!

If I basicify my rig can I share some beer? 

There seems to be two trains of thought regarding getting a good reaction:

a) you need lots of agitation and mixing
b) you need to two-stage to "push the reaction to the biodiesel side"

Jim would argue that an eductor means that you don't have to do b) - by which argument a big pump should also mean that you don't have to do b).

I know Jim doesn't mind a little 3/27 dropout in his batches because his common rail doesn't mind.  Do you get dropout Keith?

Part of me thinks that no matter how well an eductor mixes or pump churns it all up, sometimes that 3/27 clear pass won't be acheivable unless the Glycerol is dropped and a little second stage is done.

[K.H]

I normally get a no drop out cloudy,not often a clear
Im not having a go at eductors and i can see they work when set correctly,it was more the fact that if you do a two stage the eductor wont work on the second stage with a lower level,so if you want to upgrade/speedup it would be single stage= eductor or larger pump,2 stage=larger pump
 and god knows where static mixers come into it,do you know anyone who uses one? it would be interesting to see how they rate them

[K.H]

I see Jim has just said on the site that they are for single stage reactions

[Tony]

I see what you mean... you'd need two eductors at different levels for two stage processing whereas a big pump doesn't care One up for big pumps then!

Don't know anyone that uses a static mixer.

is the link gone to the two tank system?

also just had a read through that basic processor page, was this the two tank setup link?


also K.H do you have vents and venturi as in that picture?

[K.H]

Gone i think

Not a lot of the orig left

No & no

Juast had a read through it

 "Biodiesel made with this design of processor will require an aditional tank for finishing and a separate Methoxide mixer." = so does a GL? just makes it sound like a poor relation 

"You must run the pump whenever the heater is on, so that there is a steady flow of oil to cool the element."= i never have ,i always allow the temp to get to 40 before switching on the pump,95% of wvo users just use heat with no pump, the convection is enough to cool the imm
I would,nt alter the above as its obviously better,but it wouldnt apply to any wvo set ups

in 3 years i have never circulated wvo just heated to 60 odd c then naturally settle it, no way would i circulate and emulsify the oil for veg running, infact i cant say i know anyone who circulates for veg running while heating? im still on same BES element... i cook everyweek...

I thought you were happy with the changes at the time I made them.  Memory isn't good these days, but I'm sure we corresponded on the subject.

I called it basic as it had few bells and whistles, and to distinguish it from Paddy's design which needs two tanks to actually make the fuel.  Similar to a GL, other tanks are required for pre and post treatment.

If it's a problem, please alter it as you see fit, or revert back to the page before I messed it around ... here http://www.biopowered.co.uk/w/index.php?title=Processor_-_basic_design&diff=1140&oldid=1118

OK!

Err .. in retrospect, did that read as a bit aggressive? If it did, it wasn't intended to!
