In processor titrated water wash method

[nathanrobo]

Don't give up on it. Some water washing sceptics have now been converted using the titrated wash method. That carries an awful lot of weight in my book.

Nige

I was one of those sceptics, I started my bio life using demeth and settle,
I then started mist washing like Nige, but suffered emulsions (probably due to pore convertions).
Now after a few years of going back to demeth and settle I've again gone to water washing, but this time it's the titrated acid pump wash method.

So as you can see I've tried a few different ways to remove the soaps, and I'm now completely sold on washing.

Mist washed for 5 years - swore by it! Experimented with pump washing... Tank full of blamange. Started to neutralise and tried pump washing again. What a difference! Was getting bored of bio, but it's getting interesting again. Well - u gotta play!

i buy some drain block from my local store, i checked with the company and its 98% pure acid ( so gotta be careful)

after ive finished the process i let the glyc settle , tap this off, get the processor churning over then add 40ml of acid, then chuck in 15litres of water, never had any problems doing this and the acid stops the bio turning to custard too..

What temps are people pump washing at.

with the cold ambient temps some people may not be realizing that the wash water can freeze. (can it?)

My first attempt at pump washing (hit and miss without titration) was left overnight to settle and by that time the batch and wash water was at -1 deg C. water and bio would not split. (orange juice)
once heated to 3 deg suddenly everything went back to normal, bio and water split.. continued washing.

Time to bite the bullet, who sells the kit i need to titrate? 

Cheers

I start washing as soon as the gly is removed, so the acid wash is done at around 60°C,
this is generally settled overnight, drained in the morning,
then do the second wash, so it's still around 45 to 50°c.

The titration kit you want is sold by nigelb.

So a few months on what is the considered opinion of this method from those that contributed?

Are you still doing it?

What are your findings?

Have you changed your process at all?

[Head Womble]

I've stopped acid washing, I now do a 7% post reaction wash with the gly from the second stage still pressent,
this removes enough soap to not form an emulsion on the first wash.

Yes the acid wash did work and the only drawback (apart from adding another stage) was that titrated soap tests gave false readings until all the acid had been washed out.

1. Are you still doing it?

2. Have you changed your process at all?

I. Tried it but found it to be an unnecessary additional stage.

2. As the "dead man walking" above, returned to the post reaction 5/7% water wash.

Dead Womble walking, please get it right.

Dead Womble walking, please get it right.

Feel free to use either phrase, the result will be the same.

Just another wooden cross in the corner of a distant field.

This years BBB is going to be so much fun

Sorry to disappoint, but if I loose my setup I'll not be attending the BBB,
how can I turn up with diesel in the tank, that's a hanging offence as it is.

Just turning up is a hanging offence in your case and I know where you live, there's no escape.

I sounds like I'll have to attend the public hanging then.

I think that Brett Gilbert showed last year and had never made a single litre of bio fuel.....no excuse there I'm afraid Mark.

Show up and take you punishment like a man.

[thewormman]

So does that mean after 17 pages singing it's praises no-one now does it and it's not worth doing?
