Centrifuge for continuous process

[hasiframli]

Hi All,

I am going to design centrifuges for continuous biodiesel process. Does anyone know how to design this kind of centrifuge? The flowrate is 1litre/minute, and I am going to seperate those liquids:

1. Biodiesel and water
2. Biodiesel and glycerine

Please guide me. Thank you very much.

Re: Centrifuge for continuous process

You are going to design them but want someone to tell you how?
Am I missing something here or is this as flawed as it seems?

If you can design a Fuge to separate Bio from water and Glyc, You'll definitely have a winner because no one has been able to do it so far.

I have a centrifuge, got it last week from the USA. Haven't set it up properly as have to completey change my set up. Tried it out on WVO and BD the other day, it removed all water and some glys, not sure how much until I test it. If I use it at room temp (cold) it does a litre a minute, warm the oil and it does it faster. Very happy with it, once fully set up it will reduce my filtering of vo time and effort and should clean BD really easy. As it is just finished setting up the oil room and now am about to chagne it all again. Only tried 5lt of BD, but ran 100lt VO through it and was extremely happy with the results. Hoping it will remove the need to super heat the oil before processing.

I run a centrifuge as well, just for WVO, got it set up so I can flick it on in the morning and when I get back from work at night 200l of WVO are ready for the fuel tanks, marvels thing that is.

Cost a few bucks, and yes it used power, but its done in no time and I have time for a coldie or two and miss out on spills in the shed.

let us know how you go mate and best of luck!!!

Why?Is it not possible at all? So what is the best choice to separate BD from water and glycerol?

To be clear, the first stage is to extract the biodiesel from mixture of biodiesel+glyc, and after washing process, I am trying to extract the biodiesel from biodiesel+water mixture.

I assume you were thinking that I am going to separate BD from those mixture at the same time? If so, it is not. There are two different stages.

I hope somebody can guide me on this. Still a newbie here.

What is the make of centrifuge?

Hi peter1,
Is that correct?
Water and glycerine have a very different SG than biodiesel. I would have thought they would have been easy to seperate.
You learn something new every day.

Re: Centrifuge for continuous process

wish I had the cash for a centrifuge , maybe I'll have to save up.
Do they polish the Bio well ? pr is it better for WVO ?

Are you an idiot ? You want to design something that spins at approx 10,000 + RPM a chunk of aluminium around 2KG in weight and you are asking these types of questions ? DO NOT do this - or if you do - document it all for the Darwin awards

Re: Centrifuge for continuous process

Well, I am just looking for a guide. Not to tell me how exactly to build a centrifuge, just asking for guidance. But some of you guys only know how to call me an 'idiot' and whatsoever. I think this forum is not the right place for a newbie like me. Maybe this is only for so-called expert like craigcurtin. God bless you craig. Take care and thank you.

Re: Centrifuge for continuous process

hasiframli,

Perhaps if you'd started off with a question rather than a statement you would have got better information to help you. Craig is rightfully concerned for your safety.

For example you could have asked the question of how to separate glycerol, water and biodiesel. You could have even asked if a centrifuge was going to be suitable.

But given your first statement was that

I am going to design centrifuges for continuous biodiesel process. Does anyone know how to design this kind of centrifuge?

it's little wonder you've got the responses you have. Maybe English is not your first language, but this opening statement comes across as kinda crazy and alarms us.

We're a bunch of people, mostly blokes, who live and breathe this veggie oil biodiesel stuff, we practice what we preach. We welcome newcomers who ask reasonable questions and have obviously done a bunch of their own research first. Fit in with this, and you'll do fine. Push people buttons with nonsense talk and things will be more difficult for all of us.
