FO

Sure...

Why wouldn't you be using the waste for animal feed?

Biodiesel is a poor choice in that the processing and application described are rife with redundancy.

One may use straight vegetable oil which is homogeneous with the vegetable waste you've described. However you would realize greater benefit from the advise of Garthh to pelletize the pulp then burn it as the complications associated when combining the pulp and oil will eat you lunch as described by wcfloyd.

If you don't like the answers rephrase the question and add greater detail. Repeating the the same scenario and expecting a different result is....

What do you mean by soy waste, oil or pulp? If it's the oil, it can also be transesterified to form biodiesel to be blended with your present diesel. If it's the pulp, whatever for?

The question is how to keep the sludge in suspension?

Tell us more about the "Sludge" & the process that produces it.

Hi dieseldiwakar,

From what you say this 'experiment' has already been arranged?

So we will not have to wait long to see the outcome, right?

However, 1500 Kg of sludge a month is not much compared to the need in general. You may find the alterations to the nozzle and all the other details will cost more than continued use of FO? But it will be interesting to see what happens.

You may find that you will need two nozzles. One for the FO and one for the mix of waste sludge and FO. You might find that two nozzles might be useful to allow the cleaning of one nozzle while the other is still in use?

Take care and please keep in touch.

Hi bb,

You could've said, that if the customers processing were efficient the sludge wouldn't be an issue.

Hi wire,

appreciate your mention.

Yes I could have said that. , And in fact rewrote my post three times before I thought it conveyed what I thought was of critical import.

I hope it succeeds!

It may take more than one try to get the mix and the way the total mixture is burned correct? But it is no loss if it does not.

I have not heard of 'liquid' and 'solids' burned like this, and it may be the 'solids' may need to be introduced by another method, to burn successfully without screwing up the nozzle. Perhaps drying first? Only the person whom is making this studied attempt and is there at the time will know, if he has enough experience.

And that was not meant as any insult at all, OK?

My other thought is that the total amount of 'solids' or 'sludge' to be burned is not that great and it may be also, that this method might not be used 'full time'. Perhaps for a couple of days a month they will have Furnace Oil only to burn?

However, I think if the customers processing is efficient the sludge would not be an issue anyway?

Wire............. It kinda fits in well above do you not think?

Take care my friend and I really do appreciate your input, thank you.

I wasn't criticizing, you did well and succinctly.

Concerning the OP's question is the slurry homogeneous with Biodiesel?

I too think is fraught with problems.

With considerable modification a pig will fly but the pig doesn't like it and the mess is prohibitive, think of the press; it's not enough we use meal for fuel now we need ham for transportation too

Goo-ud day bb!

Hi wire,

Nice to hear from you. Thanks.

I did not take it is criticism, no problems.

Since the OP has said this is something planned for today or tomorrow I hardly thought it worth 'effort' of finding out whether or not the sludge is or would be homogeneous. I presumed they had already mixed a load and were about to try and burn it, you know? I do not really understand why they asked the question if they had gotten so far as to plan a burn test in two days, it seems is going ahead, whether or not anyone on CR4 says it is a good idea? Whatever, it is 'small beer' in the scheme of things. It seemed a few of his posts were repeated without too much extra detail added, so we do not know, as I understand it, whether this is a full scale burn or not?

Be interesting to see what happens though?

Take care my friend.

Hello Guest,

No problems my friend.

I was writing a whole lot of posts and could not always think of the correct term. I used "solid" not to denote a solid like iron or stone, but something which still have carbon solids in the form of leaves and other detritus.

I hope it works for you. As I said in a post to someone else, it may be a whole lot of trail and error, and mistakes on mistakes are made, before you are able to achieve your goal?

Take care and sincere good luck.

Hello dieseldiwaqker,

If your intent is to blend the slurry with a fuel source SWO "straight vegetable oil" is that which will be most homogeneous to the soya meal pulp slurry.

What benefit do perceive in the added cost of producing bio-diesel from SVO when SVO will suffice as the necessary fuel?

Sure...my initial response is accurate too.

I would have to agree.

I would certainly do some bench tests & see which composition stayed in suspension the longest. A small amount of detergent will probably help.

The op finally revealed that he is dealing with the crud from purifying the oil [I think].

It would still be nice to know extraction/purification process is being used solvent or steam.

There are certainly regulatory implications, assuming the processor is actually following the law

The op finally revealed that he is dealing with the crud from purifying the oil [I think].

I don't think it's from purifying oil, I think the slurry is residual from extracting oil from the seed and the resultant of filtering feed cake from the oil.

It's like pulling teeth sometimes

It's a joke

Many times people make up statistics to prove their point

What process is being used to extract the oil from the soybeans?

How is it you think we can help you?

So all waste is the same, regardless of the extraction process?

If you are trying to bury the question & obscure the meaning, how is it you think you can expect a solution?

You could dry & pelletize the waste & burn it as you would wood? The feasibility of this would depend on the extraction process...

The waste could be the whey or could be the gunk left over after deoderizing & bleaching of the oil.

I have no way of knowing with out more information.

[ this is completely on topic, contrary to what you might believe ]

I'm with Garthh. Seems like soy pulp would have more value as animal feed. Maybe you don't have animals? I suspect the pulp would separate and settle out. It would clog fuel lines and nozzels. It would also clog fuel filters.

Or are you talking about the crude glycerin waste from biodiesel production? That is quite different from soy pulp. It is a poor fuel. If you generate the soya waste and have biodiesel on hand, you can do the experiment to answer your own question. Mix them at 5 to 10 %, shake them up and see what happens. If they separate, perhaps a few drops of Dawn dish detergent(or similar) will make them compatible. This might make your fire burn a little cooler, but you could get rid of some waste.
