Yes. Actually these are 1 or 2l test batches. For agitation I use a small water pump originally designed for larger aquaria and also recently used in water cooling systems for PCs. Manufacturer says it's capacity is 700 liters per hour. Even considering higher viscosity of oil it should be enough for 5l testing container. Do you think it is ? I can provide some pictures if it helps (I've done a bit of documentation). > Do you know the purity of the KOH you are using? Yes, it's 99% pure from chemical supplier, though I've noticed it's a little bit calcinated (some flakes are too white, in my opinion). I have also tried NaOH (same purity) before with the same result. > I have heard of virgin oil containing some FFA. I have no experience > with such oil. It's probably normal, as it sounds impossible to make fresh oil with absolutely no FFAs. The question is - what amount is 'normal' and what is definately not ? -- cheers, Rafal Szczesniak **mir[at]diament.iit.pwr.wroc.pl Samba Team member mi***[at]samba.org +---------------------------------------------------------+ *BSD, GNU/Linux and Samba http://www.samba.org +---------------------------------------------------------+ _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
