Acid turns oil to dark color

I noticed in one of your last posts you said you were using 3ml H2SO4 per litre WVO and mixing for 3 hours. So you have dropped that down to an hour or so of mixing.


selective reading hmmm. I posted the results of using more acid as a possible way to process oil to take some of the unreliability out of the results for those who wanted to try the process. I don't use that much acid as a rule. I don't use the formula base on m weights either.

I know the information is in the ae thread, I posted it for buckeye.

"With an endpoint titration of 0.75- 1, it shows that most of the H2SO4 has settled to the bottom of your reactor overnight."

yes , most of the acid slowly sinks to the bottom overnight, you failed to mention the ffa, nice result from oil titrating at 16 without continuous mixing eh! so much for your theory, Confused For those who do ae, mixing throughout the process is only required if you are doing high temp (165f) AE. In this situation mixing is required to keep the evaporated and condensed methanol mixed in otherwise it just floats on top of the oil this process only takes a couple hours.

wow, looks like I shook a hornet nest with a simple question/ problem. Oops that was not my intention. So.......... my original problem persists, I have taken high titrating oil and made it titrate higher by adding methanol and acid. Where do I go from here ??? Still curious about venting.

Now all lets play nice Smile

Mixing is very important in my process. But than again i am using 30-40 times more methanol than what most folks uses. In my method if its not agitated right the FFA wont get reduced. The acid and methanol stays on top of my FFA if not mixed. In some cases it will take 100 times longer to process without agitation.

I believe when using high temperature like around 464F it is no loner necessary to use agitation.

BB when tilley or one of his clone chirp it is never nice. I will be happy to give you advice based on my experience, but not on this thread, I don't have the patients for -holes! Feel free to email me. Tom

Samuel I agree you would have to mix continuously with that amount of methanol. You can email me as well, I would like to test your process on lad scale batches. Did you know you can lower titration by simply washing the uvo with methanol? Tom

I am working with a company that uses glycerin to dry oil and reduce the FFA. If I understood him right, he gets the titration down from 14 to 5 using only waste glycerin.
