Anyone doing the glycerol remix?
I have read previously about the remix of prior batch glycerol that seemed to lower the gel point of processed bio. Girlmark's blog makes passing reference to it, but no real explanation, that I found.
It seems reasonable that there are some unutilized chemicals in the waste that could be used to pretreat the oil and lower titration by knocking some of the FFA out. I am going to try it and wondered if anyone had some pointers as far as temps and mixing times. I use KOH as a caustic, so there is no issue with gettting it mixed back in.
My plan of attack, unless diverted would be to heat to 130-140, mix for a half hour or so and let it settle out. Titrate and process. I will titrate before the remix just to see if there is an appreciable drop in value.
Thoughts on the process or first hand experiences appreciated.
