I would like to pose 2 questions to all biodiesel experts: 1-What is the maximum capacity of a transesterification(biodiesel) reactor? In other words can I react vegetable(or cooking oils) in a 2,000 gals reactor? What about 5,000 gallons? Is there a maximum capacity? What about ratio of Height to Diameter? RPM? Any publication on the subject?
2- We are thinking (our local group) on hiring a Biodiesel expert from any country of the Americas (who have had a few years experience in making biodiesel form spent oils) to come down to our place and assist us in the design, start up and training of a small biodiesel plant (from cooking oils). Capacity initially would be of less than 1,000 GPD. State your qualifications, fees etc. Thanks!
