Thanks for looking into it. Will try and rebuild it again having the nozzle back further as you suggested. Also, the oil temp was about 40 degrees. Does it need to be heated to about 120 for the venturi to work better. The design we are trying to use is a GL Eco-processor. The venturi is supposed to introduce methanol vapor back into the reaction to help dry the oil. The methoxide itself will be induced before the pump.
Do think that there are too many elbows? We did that so that the pump would be closer to the reactor and the wash / settling tanks could be close by, but if I re-plumbed again, I might be able to get rid of as many as 3. Also thinking of replacing as much 3/4" pipe on the output side as I can with 1" to reduce restriction.

thanks again.
