Acid Esterification | Forum profile

DD Thanks for confirming my gut. So if using a water absorbing material maintain temp/pressure, continue to mix until T stops dropping. If "NOT" using a water absorbing material, mix, maintain temp/pressure... then stop mixing ...hopefully, water will not kill the reaction so quickly. I have 600lbs of 1/4" to 3/4" SB (They call that size "Hole Plug"). Now lets see if it works! l8tr dennis

Or about .075% H20 by volume, a bit much for low methonal AE

Dennis -yes that would be the reason, the deadicated ae tank will have residual acid much like the processor has residual caustic after the base process. This acidic condition should not affect the ae process! Tom

Im wondering if we are headin the wrong...

dkenny, I'd give you some oil if you weren't 250miles away. Running a 3rd stage may result in any gains being negated when you loose bio during the draining. Dennis, The water is created as the FFA are esterified, so water is created until the reaction stops not just in the beginning. Morphologies? Did I say that?

Danny Not really, if it's working for ya. Should I acid treat the the tank after the finished product before my next acid treatment? would I even need to with my current process?

Buckeye, what is the BDC method, maybe i am familiar with it but not by that acronym? If water is my problem, and 95% methanol is the culprit, will adding more methanol help? I tried Double D's formula which called for more methanol and more acid but came up with the same results. So possibly I should be adding more methanol and less acid (than Double D's formula)(use the T-3x.025) and that might cure things?

True but lets not forget its not just FFA that get converted to biodiesel.. tri's are also converted.. but to determine the % converted..this would be next to impossible without something like a GC. so if we just guessed.. what would happen..could be reduce the total methanol needed?? worst case it would need a 3rd base stage instead of just 2. I'm just thinking outloud here..so this might not work at all.. If I some oil..I could...
