Lowering caustic base rate?

If you dont have enough catalyst you will not get full conversion and too much will result in excess soap. So you are right if your conversion isn't 100% at 7 leave it , I would only drop if I got excess soap which I am getting atm

Well to be honest it was only 280L as not all tins were full. But it was still a bit of a result, and it's all nice and dry as well. I'll now start running before you lot start a witch hunt

dont go less than 7....and check if the KoH is full strength. A bit extra is OK with KoH aswell as its a bit more tolerant than NaoH

3 is my norm , usualy just proess at this number and look for 27/3 pass.but since pre washing with glys have started titrating again drops to 1.5

If for any reason you can't seem to get a 27/3 pass and it does sometimes happen (though usually due to water) then you will probably be best off dropping the glyc and reprocessing. As Chug says, HMPE dropout is almost certainly due to feedstock and the temperature of the bio. The lower the temp the more likely they are to dropout as solubility in the remaining methyl esters drops. Much less of a problem now than it was in...

Can you please tell me where you get your methanol? I DON'T want to keep 205 litre drums in our very small garden - been there, done that and don't
want the t-shirt. The best source I have found so far is south bucks for £1.00 a litre collected but as this is a new source I have no idea if it is
going to be ok and reliable or not. Have tried all sorts of local 'commercial' bd manufacturers ...

from what i can read there is a few options,
let it settle drain off from the top and after a few batchies clean the settling tank
or water wash
or air bubble
or use an eco2pure tower

Can anyone point in the right direction for a connector to fit to my glyc container for venting?
Maybe one with a barbed hose connection in 8mm.

Last batch i made, used all the crappy stuff from the bottom of the tank, like pumping runny lard, anyhow dewatered to 90c, Bio is like Orange juice
after water washing, if i put some in a pan or test tube and heat it up, goes lovely and clear, then when cooled down, like orange juice again??

Using Koh at base rate of 7, but in my tit kit it says 5.5. How do you know if you can lower it?
Occaisionally I have to add a bit extra if a 27/3 has failed using 7, so this must tell me not to lower, right?

Hi all
I have been doing my tits and have yet to get one reading more than 2.0 Lowest was 1.4
My oil comes from multiple outlets (25) so it is a good old mix.
I am going to try and take a tit of the worst and best looking and see what they come out at.
Main tit is done once oil has been Dewaterd and mixed at 60 c
Are the low readings common (2.0 - 1.4)

The idea of a flash evaporator on our reactors is to remove the methanol as fast as possible reducing demeth time and energy costs to a minimum.
My flash evaporator is now fitted and setup at working pressure. It has a fan shaped discharge pattern to increase surface area and allow a greater
volume of the volatile compound to be removed from the Bio
It runs at 2.3bar pumping 9ltr/...

Friends, country men, everyone else and fellow brewers.
I've finally got round to making and fitting an Eductor to my plant. it worked better than I could have ever wished.
My plant is 50ltr (at the moment) but the eductor was developed and tested in a 100ltr tank of mixed WVO, some thick creamy stuff and nice fluid oil,
about 50/50.
The tank was heated to 65c and the eductor was...

clear things up a bit:

Hi
As the title says, what is the best additive to achive power gains from an engine that runs on bio
also is there any problems mixing it, and does its go through your filter

i picked up some oil today, and i think i was told it had been 'burnt' (or maybee that what was in it had been burnt - im not sure)
it looks like oil, only much much darker
still worthy for bio production, or not worth contaminating the rest of the feedstock with?
thanks, julian

hi guys getting to the final parts in my bio processor
what types of pumps are best to use for my reactor
when i asked jamesrl he said i would need a 80 ltr/min for a 160 ltr processor, but as im making a 275 ltr processor (to make 200ltrs of finished bio
each time) what type of pump would i need
i have a tam105 and also a copy of it as well, would one of these be good enough ...

Water washing is " old hat" we're often told. But I've spoken to a few fellow brewers recently and they have reservations about the WBD and the GL
process generally. Personally, I find it works very well in the summer but nowhere near as well in the cold weather. So, what method do you
use?

When we do a 3/27 test
Is the methanol in the bio counted ?
3/27 = 10% / 90%
If the methanol in the bio is counted
3/27 = 3 bio / (what is in the bio) + 27
Just wondering as i am finding it hard to get a perfect pass
Any matermations help pleas
