Hi Vakin; Thanks for your input. When you say 200 ml RO do you mean you wash a 1 liter test batch with 200 ml of reverse osmosis water? BTW 95 deg. C is pretty warm it may dry the fuel quicker but there are some notes on J2F that indicate biodiesel can oxidize. It may be accelerated at that temperature unless you use CO2 or N2 blanket to keep air away. Also it takes more energy to heat the fuel that much. Just a thought. Also I heard one can use an automotive air conditioner compressor as a vacuum pump. Don't know what level of vacuum it can produce but it is worth a try if the price is right.

Bit better mileage with the same power.Return line for diesel engines has a enough quantity of fuel to do "stir washing" of your BD. Important is to not get fresh water into the pump! This can be done with some modernization of your fuel tank. BTW my test batches (200 ml RO) with NaOH as catalyst every time looks bit "waterized" after third stir wash and this stay at least three days. Maybe more but I have gave the batch for physical analysis. With KOH water goes out more rapidly. In both processes esterification is 92-93%. In monday I'll know how much water has in the batch after third wash and after 95 degrees Celsius for one hour. Will inform about results, but I think the quantity will be in ppm's.
